- The development of improved dosimetry techniques, as well as patient selection and positioning during delivery of radiation therapy, were crucial to decrease the harmful effects of radiation on the intestines. (medscape.com)
Cancer5
- The risk for developing radiation-induced cancer at some point in life is greater when exposing a fetus than an adult, both because the cells are more vulnerable when they are growing, and because there is much longer lifespan after the dose to develop cancer. (wikipedia.org)
- The Japanese government argues that apart from children who contracted thyroid cancer from drinking contaminated milk, there have been no health effects among ordinary citizens as a result of Chernobyl radiation. (21cir.com)
- Often the foetus of a female patient who was exposed to radiation could experience congenital abnormalities due to the exposure to irradiation may even cause abnormal cellular proliferation which could result in cancer development [5]. (myhealth.gov.my)
- "Radiation Induced Cancer from Low Level Exposure" by J. Gofman - A book in HTML format - chapters 27-37 are yet to be published on this site (six year old promise. (calytrix.biz)
- Radiations and certain chemical agents induce DNA lesions, which may cause genomic instability and activate cancer generation. (biomedcentral.com)
Electromagnetic fields3
- Especially children and adolescents are important in the discussion of adverse health effects because of their possibly higher vulnerability to radio frequency electromagnetic fields. (biomedcentral.com)
- At the same time, there is growing public concern that radio frequency electromagnetic fields could cause adverse health effects even at exposure levels far below the reference levels [ 1 ]. (biomedcentral.com)
- In the discussion of possible adverse health effects caused by mobile phones children and adolescents are relatively important, because they are possibly more sensitive to radio frequency electromagnetic fields. (biomedcentral.com)
Shielding3
- Radiation shielding usually consist of barriers of lead, concrete or water. (radiation-dosimetry.org)
- There are many many materials, which can be used for radiation shielding, but there are many many situations in radiation protection. (radiation-dosimetry.org)
- A4: Engineering controls, such as shielding and controlled access areas, reduce radiation exposure by physically preventing or limiting access to high-risk areas. (steelroofing.us)
Significantly4
- Do cheap sunglasses (with UV protection notice on them) really offer significantly worse protection? (stackexchange.com)
- BC is a potent antioxidant, and studies demonstrate that BC significantly reduces radiation-induced DNA damage including γ-radiation [ 11 ] and UV radiations [ 12 ]. (biomedcentral.com)
- The consequences of endocrine disrupting chemicals (EDCs) on reproduction are popular, whereas their developmental effects are significantly less characterized. (thetechnoant.info)
- We usually do not statement the effects which were present in significantly less than 70% of treated embryos. (thetechnoant.info)
Lethal1
- The commonly consumed antioxidants β-carotene and tea polyphenols were used to assess their protective effects against γ-radiation induced sex-linked recessive lethal (SLRL) mutation and oxidative stress in Drosophila melanogaster . (biomedcentral.com)
Doses below1
- The report states that, if all radiation doses below a half-rad are harmless, then Chernobyl creates "zero risk" for some 500 million people exposed by its fallout. (ratical.org)
Possible adverse health effects1
- In comparison to non-participants, parents and adolescents with a higher level of education who possessed a mobile phone and were interested in the topic of possible adverse health effects caused by mobile telecommunication network frequencies were more willing to participate in the study.

Deterministic2
- Deterministic effects are those that reliably occur above a threshold dose, and their severity increases with dose. (wikipedia.org)
- High radiation dose gives rise to deterministic effects which reliably occur above a threshold, and their severity increases with dose. (wikipedia.org)
Regulatory2
- On this basis, the regulatory authorities take the necessary measures, such as the temporary or permanent exclusion from work as a classified radiation worker. (ensi.ch)
- The focus of ALARA is to keep each worker's occupational radiation exposure as far below the federal and state regulatory dosage limits as possible. (safetystratus.com)
Harm4
- Any decision that alters the radiation exposure situation should do more good than harm. (radiation-dosimetry.org)
- In case hormesis cannot be sold to the public, the next best outcome would be evidence supporting a threshold-dose of radiation below which no harm at all occurs. (ratical.org)
- Even back then the International Commission on Radiation Protection thought that model might not be correct but they adopted it because, on the available evidence it would Not Underestimate the risk of harm. (joannenova.com.au)
- With the intention of reducing the potential harm from the exposure to radiation, several rules were suggested to protect the foetus. (myhealth.gov.my)
Exposure levels1
- When the effect of the mixture can be estimated from the sum of the exposure levels (weighted for potency in dose or concentration additivity) or the probabilities of effect (response additivity) of the individual chemical mixture components. (cdc.gov)
