International Commission on Radiological Protection (ICRP) revised its
1990 Recommendations (1991) in the form of “2007 Recommendations of the ICRP” (2007).
The fundamental principles of radiological protection in the revised System
of Radiological Protection are: Justification, optimization and application of
dose limits are apply to all exposures to ionizing radiation from any source.
The total harm to health experienced by the exposed group of persons and its
descendants as a result of the doses received is termed as detriment. The
detriment takes into account the stochastic quantities.
However, the research over the years also indicates stroke and heart
disease may well be caused by chronic or acute radiation exposure at doses of
the order of 0.5 Gy or less.
Now the acceptance of this non-cancer detriment in the risk assessment by the ICRP may change the protection strategies in the future?
