Leptogenesis is a class of scenarios in which the cosmic baryon asymmetry originates from an initial lepton asymmetry generated in the decays of heavy sterile neutrinos in the early Universe. (hindawi.com)
We review its motivations and the basic ingredients and describe subclasses of effects, like those of lepton flavours, spectator processes, scatterings, finite temperature corrections, the role of the heavier sterile neutrinos, and quantum corrections. (hindawi.com)
Some physicists speculate that dark matter is made of "sterile neutrinos," for example, theoretical ghostly particles that barely interact with matter. (space.com)
It will be part of the Short Baseline Neutrino (SBN) programme at Fermilab, dedicated to the study of sterile neutrinos. (caburnuhv.com)
In this work we assume the existence of heavy (mainly sterile) neutrinos, n h , with a small mixing with the muon neutrino. (arxiv-vanity.com)
Called sterile neutrino1
But the analysis of the beta decay spectrum of tritium also allows to search for the trace of a hypothetical fourth neutrino, called sterile neutrino. (cea.fr)
Neutrino1
The Neutrino Platform pulls together a community that is scattered across the world," says Marzio Nessi, CERN Neutrino Programme project leader. (caburnuhv.com)
Drapes3
The drapes are developed to reduce scatter radiation at the source, creating a scatter-free zone, thereby reducing harmful ionizing radiation exposure. (imgsol.com)
However, in operating theatres, for example, physicians, nurses and technologists who are near the patient must be protected using the appropriate ant-scatter radiation drapes. (imgsol.com)
Z&Z Medical carries a wide variety of High Pressure Disposable Syringes , Skin Markers , Sterile Drapes and Covers , Cassette Covers , Labels and Stickers to just name a few. (zzmedical.com)
MAVIG3
Sterile protective gloves from MAVIG for the use against scattered X-ray radiation allow optimization of the X-ray protective measured for medical staff. (advanced-hc.com)
With the the X-ray absorbing, sterile gloves HS100 MAVIG offers personal protection equipment, which serves the purpose of protecting from secondary X-ray radiation. (meditron.ch)
Often some sensitive parts of the body are not yet protected, MAVIG offers a broad range of PPE products to guarantee optimal protection against radiation. (mavig.com)
Gloves6
We also have Sterile Radiation Gloves that protect hands from scatter radiation during interventional radiology or surgical procedures. (zzmedical.com)
Worthy to note is that a protective factor of 2 is achieved when using the gloves in the scattered radiation area (X-ray tube voltage of 60 - 80 kV). (meditron.ch)
Great elasticity in combination with an excellent anatomical fit allows for optimal working conditions, bringing it in the same category of high quality surgical gloves, while additionally offering efficient protection against secondary X-ray radiation (scattered radiation). (meditron.ch)
This regulation recommends the usage of surgical gloves with radiation protective properties as part of protective clothing for medical staff participating in Angiography, cardiac catheter, neurological, urological, and intra surgical X-ray examinations, as well as CT interventions. (meditron.ch)
One option are X-ray absorbing, sterile gloves. (mavig.com)
Nowadays, the characteristics of these gloves are so similar to conventional surgical gloves that they can be integrated into the radiation protection concept without any problems. (mavig.com)
Interventional2
Radiation safety is a common concern for patients, physicians, and clinical healthcare workers in many departments, including interventional cardiology, radiology, and surgery. (imgsol.com)
As the number of interventional procedures increases due to advancements in both technology and clinical efficacy, medical staff are subjected to potential exposure from these sources of radiation. (imgsol.com)
Latex Free1
Lead, powder and latex-free Radiation Attenuating Glove designed to provide increased protection from direct x-ray beam and scattered radiation. (newmarsgroup.com)
Exposure10
During most imaging procedures, the patient's body is the object that deflects the radiation and causes it to scatter around the room, potentially risking clinical healthcare workers and the patient to unnecessary radiation exposure. (imgsol.com)
In some cases, as with dental offices, the technologist is able to step out of the room during the examination, thus lessening the chance of an accidental exposure from scatter radiation. (imgsol.com)
This radiation exposure is dependent on the duration of time, distance from the radiation source, and the physical shielding being implemented. (imgsol.com)
Radiation exposure over a prolonged time period can produce biological effects that can potentially cause short and long-term health issues. (imgsol.com)
Drastically lowering the equivalent radiation exposure for medical personal is a must, and not just to the permissible levels of the effective dose. (meditron.ch)
The concept of optimization in radiation protection specifies that every possible measure must be taken to minimize the dosage from radiation exposure. (meditron.ch)
Without effective on-site ceiling mounted scatter radiation protection, the skull can be exposed to a high amount of radiation depending on the procedure and exposure time. (mavig.com)
This means that any possible measure to minimize exposure to radiation must be taken. (mavig.com)
Bruns and his colleagues have made one that changes color when exposed to gamma radiation - envisioning it might someday work as a built-in exposure meter. (lehighuniversity.org)
Disposable1
During the VLOK procedures are used sterile disposable fibers KIVL-01 with a needle, which are connected to a special terminal emitter. (lavky.com)
Secondary radiation4
Scatter radiation is defined as a type of secondary radiation that occurs when the beam intercepts an object, causing the beam of X-rays to be scattered in different directions. (imgsol.com)
The product is intended for the shielding against secondary radiation and provides efficient protection. (meditron.ch)
The reason for this is that the secondary radiation emitted from a lying patient does not only hit the front of the eye lenses but rather comes from below or from the sides at different angles. (mavig.com)
Gamma radiation1
Bruns and his colleagues have made one which modifications colour when uncovered to gamma radiation - envisioning it would sometime work as a built-in publicity meter. (labornewswire.com)
Apron4
Most importantly, this means the user isn't breaking the sterile field when removing the apron. (aadcomed.com)
Regardless of the on-site radiation protection, a radiation protective apron should always be supplemented with some form of thyroid / sternum protection, as the thyroid is an organ which is particularly sensitive to radiation. (mavig.com)
2 It is important to make sure that the thyroid protection and the protective apron completely overlap on the front so that there are no gaps in the radiation protection. (mavig.com)
3 In workplaces where you usually stand with your side towards the radiation source (e.g. in cardiac catheter laboratories), the radiation protective apron should at least have one sleeve. (mavig.com)
Interacts1
The scattering of the radiation beams occurs when a direct radiation beam interacts with body tissue, causing the ionising radiation to be scattered indirectly throughout the surrounding clinical operating environment. (imgsol.com)
During a diagnostic imaging procedure, as the x-ray beam is passed through the patient's body, a doctor or nurse may come in contact with the direct beam if they enter the direct path of the radiation beam. (imgsol.com)
We are participating in a Consultative Committee for Ionizing Radiation (CCRI) comparison of thermal neutron fluence rate measurements, characterizing four different beam qualities at the NCNR, and carrying out comparisons of NIST standard neutron sources. (nist.gov)
Protection6
These independent test results are certified by the National Physical Laboratory, and as a result, this protection meets the BS EN 6133-1:2002 standard. (aadcomed.com)
The product is classified as a powder-free sterile glove, which features the additional benefit of X-ray protection properties on top of its core material characteristics of impermeability and protection against chemicals and microorganisms. (meditron.ch)
As a first step, you should always use on-site radiation protection, such as table-mounted lower body protection and ceiling-mounted protective shields. (mavig.com)
The extra radiation protection material ensures that the particularly delicate breast tissue is no longer exposed. (mavig.com)
