The Radiation Protection Register is a central dose register for the surveillance of occupational radiation exposure. It has the task to control continuously the keeping of the body dose limits of all occupationally exposed persons in Germany and the issuing of radiation passbooks for itinerant workers. The Radiation Protection Register contributes to the international development of the occupational radiation protection as to the state of science and technology and to the harmonization of the occupational radiation protection monitoring in Europe.
As a result of the new Radiation Protection Act (Section 170 StrlSchG) there will be important changes of the data that have to be submitted to the Radiation Protection Register. In particular all individuals subject to registration in the Radiation Protection Register (occupationally exposed individuals and radiation passport holders) need a unique identification number: the Radiation Protection Register Number (SSR Number) starting from 31 December 2018. With the SSR Number, it will be easier and better possible to assign and balance the individual dose values from occupational radiation exposure in the BfS Radiation Protection Register. Moreover it substitutes the previous Radiation Passport Number.. Since 31 December 2018 it is possible to apply for the SSR Number at the BfS. The address of the SSR Portal for the application for the SSR Number is: ...

The research, conducted by the Ministry of Education, Culture, Sports, Science and Technology and the Fukushima plants operator, Tokyo Electric Power Co. (TEPCO), assumed that current radiation levels would be unchanged for a year and that exposed individuals would remain outdoors for eight hours a day.. Of 128 locations within the 20-km zone, researchers projected that annual radiation exposure would exceed 100 millisieverts in only 17 places.. According to the International Commission on Radiological Protection (ICRP), annual radiation exposure exceeding 100 millisieverts poses dangers to health. Annual exposure exceeding 500 millisieverts is associated with a drop in lymphocyte cells in the blood.. The worst-contaminated location had a radiation level that might expose individuals to more than 500 millisieverts in a year. But nearly half of the sample locations had radiation levels below the 20 millisieverts standard used by the central government as a guideline for issuing evacuation ...
Radiation protection technicians protect workers, the general public, and the environment from overexposure to radiation. Many of their activities are highly technical: They measure radiation and radioactivity levels in work areas and in the environment by collecting samples of air, water, soil, plants, and other materials; they record test results and inform the appropriate personnel when tests reveal deviations from acceptable levels; they help power plant workers set up equipment that automatically monitors processes within the plant and records deviations from established radiation limits; and they calibrate and maintain such equipment using hand tools.. Radiation protection technicians work efficiently with people of different technical backgrounds. They instruct operations personnel in making the necessary adjustments to correct problems such as excessive radiation levels, discharges of radionuclide materials above acceptable levels, or improper chemical levels. They also prepare reports ...
Ionizing radiation is used extensively in the field of medicine for either diagnosis or treatment. Hence, an understanding of radiation safety principles and how to apply them in practice is critical for nursing practice. The study was performed to assess nurses knowledge of ionizing radiation and radiation protection during mobile radiodiagnostic examination. A quantitative, descriptive cross-sectional survey was employed for this study to provide better means of investigating and assessing the knowledge, misconceptions and perceptions among 43 nurses assigned to clinical rotations in selected wards of the Korle-Bu Teaching Hospital regarding ionizing radiation and its radiation protection. A purposive sampling method using self-administered questionnaires was used to obtain data in respect of the study. The obtained data was analyzed using SPSS version 16.0. Out of the population of 43 nurses, 25.6% (n=11) were of the view that objects in the X-ray room emitted radiation after an x-ray ...

It is sad and discouraging that NCRP-136 seeks to misrepresent the results of such a large number of sound and thorough studies, and fails to consider objectively the huge discrepancy between the observational data and LNT predictions, which clearly shows that LNT fails the test of reality. Treating many other studies in the same manner, it is our opinion that the NCRP committed a severe violation of the scientific method in defense of the obsolete LNT concept, which has now become a health and societal hazard..

Protecting medical workers and those exposed to naturally occurring radiation, such as air crew and miners, is the next frontier in occupational radiation protection, participants of a conference on the subject in Vienna learned last week.
Creating a scientifically semi-valid super-soldier, part 5: Heart and circulatory system. So youve designed a supercreature for those hard tasks in space. Whether its a miner, a soldier or something else, they are going to be prone to damage to themselves and their suit. Or you might have a police force that has to deal with a lunatic carrying a particle beam. "No biggie!" you think, "they are designed to take some damage!" Then after a little while the cancers start popping up all over their bodies and they die horrible deaths, or keel over on the spot from acute radiation poisoning.. Dont let that happen to you! Our scientists have found various ways (I hope) to build in radiation protection regardless of that radiation being from space, the scatter of radiation of a particle beam or just some emergency repairs of your local nuclear reactor.. The solutions would need to be buildable, maintainable and repairable by a biological creature. If you know a way you can build a metallic plastic or ...

Reston, Va. (April 15, 2014) - Image Wisely recently launched its third Image Wisely Radiation Safety Case - CT Brain Perfusion Dose Optimization. This is the latest in a series of free, online and mobile-compatible educational offerings, developed with the assistance of the American College of Radiology, that allow radiologists, imaging technologists and medical physicists to assess their understanding of important radiation safety concepts - including dose monitoring and optimization.. "Several years ago, the U.S. Food and Drug Administration investigated a series of unexpected high exposures associated with CT brain perfusion procedures that resulted in skin injuries and hair loss," said Lifeng Yu, PhD, primary author of the new radiation safety case. "In an appropriate clinical setting where CT perfusion exams are justified and scanning techniques are correctly used, it is unlikely that the radiation dose would reach the threshold level for skin burns to occur. This case presents strategies ...

Following radiation-release incidents, rigorous evaluation of radiation exposure is fundamental for better understanding of the future health risks as well as for effective radiation protection planning. After the Fukushima incident, because of limited scientific evidence and knowledge with regard to dose reconstruction, we have faced inaccuracy in the government dose estimation model.9 ,12 Hence, to ensure as much accuracy as possible, direct dose measurements using individual radiation dosimeters have been adopted by many local authorities as a major component of their radiation protection policies.14 However, evaluations of proper dosimeter use by individuals is greatly lacking; the errors arising from improper use of the dosimeters are also unknown because of lack of information on users daily behaviour and the conditions under which the dosimeters are worn. Here, the external radiation screening programme provided by Minamisoma City offered a unique and valuable opportunity to address ...

A lot of research has been undertaken on the effects of low-level radiation. The findings have failed to support the so-called linear no-threshold (LNT) hypothesis. This theory assumes that the demonstrated relationships between radiation dose and adverse effects at high levels of exposure also applies to low levels and provides the (deliberately conservative) basis of occupational health and other radiation protection standards.. Increasing evidence suggests that there may be a threshold between 100 and 700 mSv below which no harmful effects of radiation occur without effective cellular repair. However, this is not yet accepted by national or international radiation protection bodies as sufficiently well-proven to be taken into official standards. Nevertheless, at low levels of exposure, the bodys natural mechanisms do repair radiation and other damage to cells soon after it occurs, and some adaptive response is stimulated which protects cells and tissues, as with exposure to other external ...

Our results show that 6 of 6 pharmacologic inhibitors with different chemical structures and mode of actions inhibit the canonical pathway of NF-κB activation (consisting of IKKβ/IκB/NF-κBp65) and provide protection against radiation-induced overall lethality and damage to multiple organ systems of the developing zebrafish. By contrast, 3 of 3 proteasome inhibitors did not afford radiation protection, but radiosensitized zebrafish embryos to the lethal effects of ionizing radiation. Taking into account that each of the pharmacologic agents used in this study is likely to affect targets other than NF-κB, it is remarkable that radioprotection cosegregated with interference with activation of the canonical pathway to NF-κB. This observation suggests that NF-κB may be the relevant target for radiation protection by pharmacologic IKK/NF-κB inhibition.. Currently, there is no consensus about the functional contribution of NF-κB activation to the radiation response (44). Abundant reports of ...
In the wake of the Japanese nuclear disaster, radiation has contaminated the food and water supply and the ocean in Japan. Radioactive particles have been carried to distant lands, though no dangerous levels have been detected in other countries. During this time of possible exposure we need to protect ourselves from the toxicity of heavy metals and radiation. Anyone could be exposed to radiation from the nuclear reactors in Japan through contact with contaminated products or travelers, or by ingesting contaminated food, even if the exposure is relatively low in level.. There are three simple principles involved in detoxification. The most important is chelation, or the binding and removal of metals and other toxins from the body. Second, the body has its own methods of detoxification which can be encouraged. And third, antioxidants will scour and remove free radicals that have been created by oxidative damage. Everyone can easily take supplements to produce these results and protect the body ...

Ionizing radiations such as γ-rays and X-rays are radiations that have sufficient energy to displace electrons from molecules. These freed electrons then have the capability of damaging other molecules and, in particular, DNA. Atoms of the DNA target may be directly ionized or indirectly affected by the creation of a free radical that can interact with the DNA molecule. In particular, the hydroxyl radical is predominant in DNA damage. Thus, the potential health effects of low levels of radiation are important to understand in order to be able to quantify their effects. Cancer has been the major adverse health effect of ionizing radiation. National Council on Radiation Protection (NCRP) Report 160 gives a summary breakdown of exposure sources in Figure 25-1. ...

In 1956 the US Department of Defense directed the U.S. Army, Navy & Air Force to investigate the biological effects of exposure to RF and M/W frequency EMF. In 1957 they reported many implications: serious damage to the eye, evidence it can cause cancer, damage major organs and disrupt important biological processes. It harms the immune and nervous systems, behavioral effects, ability to learn, damages the chemical barrier that prevents blood toxins from entering the brain; possibly causes genetic defects, birth defects and general effects on growth and aging processes! They noted that pulsed radiation appeared to be more harmful than non-pulsed radiation. [15] [16]. More evidence can be seen in the 1971 Naval Medical Research Institute bibliography citing more than 2,300 studies, and still more in 1986, by the U.S. National Council on Radiation Protection & Measurements. [17][18][19] Tellingly, in 1976, the US informed its allies (which would have included Canada) not to talk about NON-thermal ...

330.10 Introduction - Ensuring contamination does not exist during and after the use of radioactive materials is a key component of any radiation safety program. All users of unsealed radioactive materials must conduct contamination surveys as required below. Records of the contamination surveys, regardless of whether or not contamination is found, must be kept in a clear and concise format that can be easily understood by the radiation safety officer or other inspector. All records of personnel and area contamination surveys must be retained by the authorized user for 3 years.. 330.20 Frequency of Surveys - Contamination surveys must be conducted of the immediate area, storage areas, and any other area that has a possibility of contacting radioactive material. The frequency of these surveys will be determined initially by the Radiation Safety Committee when a new application is reviewed and approved. After an application is approved, survey frequency will be determined by the radiation safety ...

Lead aprons are traditionally used in orthopedic surgery rooms, cardiac catheterization labs, radiology areas, radiation oncology facilities and beyond, as a protection from radiation. Unfortunately, they do not have a good process to disinfect them daily. Current practice to clean lead aprons involves using chemical wipes once a week/10 days/month, which is ineffective. As a result, these lead aprons have been found to harbor infectious pathogens such as Methicillin Resistant Staphylococcus aureus (MRSA), Clostridium difficile, Carbapenem Resistant Enterococci (CRE), that could be passed on the patients during surgeries and other procedures. Autoclaving cannot be used because it will melt the nylon covering and also heat up the metal lead to a high temperature and cooling takes a very long time as well.. "Nosocom Solutions Inc." has developed a proprietary disinfection tool- "DCab" to provide efficient and quick disinfection of lead aprons and white coats used in healthcare settings. It uses ...
Radioiodine has been used in nuclear medicine for the treatment of thyroid diseases such as Thyroid Cancer and Thyrotoxicosis for many years. The treatment renders the patient radioactive. To minimize the dose to the patients relatives and the general public, restric-tions are imposed on the behaviour of the patient. This project presents the person dose equivalents actually received by family members of radioiodine patients following such restrictions. The family members wore hospital ID-bands on left and right wrists for up to four weeks. Each ID-band contained two LiF: Mg, Ti Thermo Luminescence Dosimeters (TLD) calibrated to measure air kerma. The TLDs were analysed and a total person dose equivalent received by the relative was calculated from the measured air kerma values. The results were compared to the dose constraints imposed by The Swedish Radiation Protection Authority (SSI FS 2000:3) in order to confirm that the new set of restrictions used at Karolinska University Hospital ...
By the way, I have been part of the design and engineering team for a CT scanner, and "measuring emitted radiation" turns out to be a far more difficult problem than it might at first seem, doubly so when we leave the realm of "testing on the factory floor" and enter the realm of "testing at an installation 2000 miles away and 4 years later". We put enormous effort into this, as did every other maker, in our attempts to ensure that the machines were not only safe when they went out the door, but stayed safe when used in the field, even when used outside recommended operating procedures. But its a very hard problem under the best of circumstances, and those are NOT the circumstances we are seeing with the TSAs scanners ...
Power App today introduced GeigerMap 1.0 for iOS, their new Health & Fitness app that provides updated radiation readings from more than 7,500 official and private measuring stations worldwide. GeigerMap consists of a searchable, global Google Map that displays crowd-sourced Geiger counter readings. Each colored pushpin can be tapped to read the name of the town or city and its current radiation level. The map offers an instant visualization of radiation levels, with green pins symbolizing a reading of 180 CPM (Counts Per Minute) or less (normal), violet pins 180 - 600 CPM (high), and red pins 600 CPM or more (dangerous).. With accidents at nuclear power facilities in the news, citizens of many countries have been concerned for their safety. Owning an inexpensive Geiger counter is not a practical solution, since these devices are too inaccurate to be useful. The CPM readings from a reliable Geiger counter measure a broad range of radiation including alpha, beta, gamma, and mixed particles. When ...
The Fukushima disaster caused the largest discharge of radioactivity into the ocean ever seen. At this point after the nuclear disaster however, scientist expected that the radiation levels in the waters surrounding the island would have decreased ever so slightly. Well, it hasnt. In fact, they have stayed "stable" since the SHTF over there. Looks like contaminated sediment in water runoff, hot micro-organism decay in the sand, and "continuing leaks" from the plant are to blame for this steady radiation level. After 18 months, the cesium-137 levels in bottom dwelling fish hasnt changed much either. As such, the radiation is finding itself in the food chain still ...

NRC is moving forward on publication of changes to 10 CFR Part 35. The proposed rule addresses three ongoing rulemaking projects and several other related topics. First, this rule proposes amendments to the reporting and notification requirements for a medical event (ME) for permanent implant brachytherapy. Second, the rule proposes changes: (1) to the training and experience (T&E) requirements for authorized users (AUs), medical physicists, Radiation Safety Officers (RSOs), and nuclear pharmacists; (2) to the requirements for measuring molybdenum contamination and reporting of failed technetium and rubidium generators, and (3) to allow Associate Radiation Safety Officers (ARSOs) to be named on a medical license. Third, the rule proposes changes to address a request filed in a petition for rulemaking (PRM) (PRM-35-20) to exempt certain board-certified individuals from certain T&E requirements (i.e., “grandfather†these individuals) so that they may be identified on a license or permit ...

Radiation can be harmful to living creatures. Radiation can harm living things directly by damaging their cells. The cells might stop functioning, or they might be unable to reproduce. Radiation can also cause cells to reproduce in an out-of-control fashion, causing cancer.. Radiation can also interfere with the reproduction of living things. It can cause sterility, making reproduction impossible. It can also cause mutations in offspring, which are usually detrimental or even fatal.. Animals (including humans) tend to be more susceptible to the harmful effects of radiation than plants. Some types of microbes are tolerant of high doses of radiation that would easily kill multicelled organisms.. Natural sources of radiation play a role in the long-term evolution of species. Some (a very, very tiny fraction) mutations caused by radiation turn out to be beneficial. They give certain organisms a better chance to survive. Sometimes mutations caused by radiation produce a more successful and ...

Radiation protection guidance for dentists using certain new types of scanners is published today by the Health Protection Agency.. In the past few years, specialist dental surgeries all over the UK have been introducing cone beam computed tomography (CBCT) technology to aid treatment.. They are used for specialist examinations and can deliver higher doses of radiation than other X-ray equipment that dentists use.. Because of the rapid uptake of this new technology, and a lack of specific safety guidance on its use, the Health Protection Agencys dental radiation specialists assembled a group of experts to formulate guidance for dentists.. Dr John Cooper, director of the Health Protection Agencys Centre for Radiation, Chemicals and Environmental Hazards, said: Cone beam computed tomography is a new and useful tool for dentists. However, like any X-ray equipment this technology utilises radiation and therefore there are risks.. I am sure that the detailed and thorough work undertaken, and ...

For use in biomedical imaging experiments, the brilliant X-ray beam produced by the MuCLS source is coupled to the Biomedical X-ray Imaging Beamline in the MuCLS-BXIB set-up. All mandated radiation protection measures will be implemented during construction of the beamline. It will also be fitted with the radiological diagnostic systems necessary to ensure long-term beam stability, which is essential for high-resolution computer tomography.. Specifically, monitors will be installed that track the precise position of the X-ray beam, which will make it possible to adjust its trajectory via an online feedback system. In addition, filters, focusing devices and various detection systems will be integrated into the beamline, which together enable the beam to be targeted with an accuracy of between 0.5 μm (for a field of view of 1.0 mm diameter) and 30 μm (at an FOV of approximately 60 mm). For this purpose, high-resolution indirect CCD detectors (equipped with a scintillator layer to convert ...

Labeling of HDs is an extremely important aspect of personnel safety. Without adequate HD labeling, personnel are placed at risk of accidental exposure to HDs. All HDs should be labeled clearly with chemotherapy warning labels. Injectable HD agents should be labeled as "opened" or "reconstituted" on a specific date and the concentration of the reconstituted agent should be indicated. "Look-alike, sound-alike" describes drugs that are spelled and pronounced similarly but are different. The term came about in response to errors involving inadvertent misfills of drugs, for example, vincristine being confused with vinblastine. A simple practice that many pharmacies now follow is arranging their medication stock alphabetically by generic name using a "Tall Man Lettering System." This is a simple way to emphasize spelling and pronunciation differences between drugs (e.g., vincristine is written as vinCRIStine and vinblastine is written as vinBLAStine). Appropriate labeling of mixed chemotherapies can ...

II. PROCEDURES A. General RAM Safety Precautions Safety, personal hygiene, and general operating procedures in a radioisotope research lab are similar to those practiced in any laboratory in which hazardous materials are used for research. Therefore, sections of the VIMS/SMS Chemical Hygiene Plan pertaining to general safety principles, housekeeping, maintenance, and laboratory facilities should be reviewed by all users and where appropriate, integrated into radioisotope safety procedures. Equipment used with RAM shall be kept separate from other equipment and appropriately labeled. Once used with RAM, equipment shall not be used for non-radioactive work unless appropriate safety and protective methods are employed. Furthermore, equipment used in RAM research shall not be disposed of as nonradioactive material until it has been determined to be free of radioactive contamination. Appropriate survey methods and documentation are required and the removal or defacing of all radioactive symbols or ...

I entered the hospital on November 14th 2011 to begin my conditioning regiment. On this first day, I had a small procedure where a surgeon inserted a catheter called a double lumen broviac into a main vein near my heart muscle. The broviac would allow greater amounts of medication to enter my body quickly. The next nine days would be the most grueling days of my life. On November 15th I began three days of total body irradiation with radiation levels so high that if they werent split up, I would have died in about two weeks. After radiation therapy and for the next four days, I received chemotherapy. Before I knew it, it was Tuesday November 22nd which was my day of rest, and my body was allowed to stabilize. I know therapy is associated with recovery and some discomfort can be expected, but what I received was more than I could imagine. One type of medicine required me to shower every two hours because the residue that exuded from my skin could cause irreversible skin damage. During the other ...
I am speaking specifically about the plans your government has to install smart meters in every home and apartment. There are many reasons for concern, but my prime one is the high level of radiation emitted by the meters. Compounded by the close proximity of several within a short distance in a neighbourhood, and the reflective element within a home actual radiation levels are even higher. To substantiate my statement, I refer you to the link at http://sagereports.com/smart-meter-rf/ ...

In this paper we present the comparison of simulations with the numerical codes COREDIV and SOLPS5.0 for JET L-mode discharges with ITER like wall (ILW). The simulations have been performed for L-mode shots with and without nitrogen seeding (#82291 - 9) which are characterised by relatively low auxiliary heating power (P-NBI = 1.1 MW) and low electron density (n(e) = 2.35 x 10(19) m(-3)). Comparisons are made to the experimental measurements (e.g. radiation levels, plasma profiles) and the differences between the results from the two codes (e.g. temperature and density profiles at the outer divertor plate) are shown and discussed.. ...
