Radiation-induced cancer. Exposure to ionizing radiation is known to increase the future incidence of cancer, particularly leukemia. The mechanism by which this occurs is well understood, but quantitative models predicting the level of risk remain controversial. The most widely accepted model posits that the incidence of cancers due to ionizing ...
Cancer slope factors (CSF) are used to estimate the risk of cancer associated with exposure to a carcinogenic or potentially carcinogenic substance. A slope factor is an upper bound, approximating a 95% confidence limit , on the increased cancer risk from a lifetime exposure to an agent by ingestion or inhalation .
Environment portal. Ecology portal. v. t. e. Electromagnetic radiation can be classified into two types: ionizing radiation and non-ionizing radiation, based on the capability of a single photon with more than 10 eV energy to ionize atoms or break chemical bonds. [1] Extreme ultraviolet and higher frequencies, such as X-rays or gamma rays are ...
The result is a lifetime risk and a five-year risk based on factors that have been tied to a higher risk of breast cancer. For comparison, it also gives an average risk for U.S. women of the same ...
Radiation hormesis. Alternative assumptions for the extrapolation of the cancer risk vs. radiation dose to low-dose levels, given a known risk at a high dose: supra-linearity (A), linear (B), linear-quadratic (C) and hormesis (D). Radiation hormesis is the hypothesis that low doses of ionizing radiation (within the region of and just above ...
5. 40% of all cancers are preventable. Here’s what you can do to keep yourself safe. Seven modifiable risk factors are responsible for 40% of cancers, according to the AACR: smoking, excess body ...
Your Disease Risk is a publicly available health risk assessment tool on the Internet. [1] Launched in early 2000 and continually updated, the site offers risk assessments for twelve different cancers and four other important chronic diseases: heart disease, stroke, diabetes, and osteoporosis. The site began in 1998 as a pen and paper ...
The linear no-threshold model (LNT) is a dose-response model used in radiation protection to estimate stochastic health effects such as radiation-induced cancer, genetic mutations and teratogenic effects on the human body due to exposure to ionizing radiation. The model assumes a linear relationship between dose and health effects, even for ...
