The National Academies' National Research Council has produced a series of reports on BEIR, and the seventh report of this series has been released.
7) Although in the past it has been argued that the biological damage and health risks from ionizing radiation may not have a linear relationship with dose, the BEIR committee concluded that the biological and biophysical data supports a linear no-threshold (LNT) risk estimate model that indicates that even the smallest dose of low-level ionizing radiation has the potential to cause an increase in health risks to humans.
Most Americans aren't exposed to plutonium, but according to the National Academy's BEIR V report, here's what a typical American receives each year in other types of radiation, expressed in millirems:
The National Academy of Sciences BEIR V estimates that a typical person who receives a single, 10,000 mrem dose of gamma radiation to all organs increases his lifetime risk of cancer by 0.
Berrington de Gonzalez relied on BEIR VII to derive her estimate of 29,000 additional cancers resulting from CT scans performed in 2007.
Every parameter in the BEIR VII model has a distribution of possible values," he says.
EPA currently uses a risk projection model developed by the National Academy of Science (NAS); this model is published in the BEIR IV report (23).
Using the modified BEIR IV model, EPA estimates that the number of annual U.
In 1999, the BEIR committee reanalyzed these data and derived two models for lung cancer risk from radon exposure (BEIR 1999).
In 1999, the BEIR committee conducted such an analysis of the five cohorts of miners with adequate smoking data and found that lung cancer risk due to radon exposure differs according to smoking status (BEIR 1999).
For the purpose of the BEIR
VII report, the authoring committee defined low-LET radiation as levels up to about 100 mSv.
Authors Jean-Claude Van Rijckechem and Pat van Beirs won a screenwriting award at the Cannes Film Festival for their screenplay Moscow-Belgium; here they have teamed with translator John Nieuwenhuizen to create an engaging, well-paced story that also gives a vivid picture of life in the Middle Ages.
