UNSCEAR 2001 Report

Hereditary Effects of Radiation

United Nations Scientific Committee on the Effects of Atomic Radiation
UNSCEAR 2001 Report to the General Assembly, with Scientific Annex

In this 2001 Report, the United Nations Scientific Committee on the Effects of Atomic Radiation has completed a comprehensive review of the hereditary risks to offspring following parental exposure to radiation. This report includes an evaluation of those diseases that have both hereditary and environmental components, the so-called multifactorial diseases. The new information presented in this report suggests that radiation is less likely to have adverse genetic effects than had been assumed. This report provides a unique scientific basis for estimating radiation risk, establishing radiation protection and safety standards and regulating radiation sources for governments and organizations throughout the world.
