REVIEW AND SUMMARY OF STANDARDS
A.
The International Commission on Radiological Protection (ICRP)
The ICRP originated in the Second International Congress of Radiology
in 1928.
It has been looked to as the appropriate body to give general
guidance on widespread use vf radiation sources caused by rapid developments in the field of nuclear energy.
ICRP recommendations deal
with the basic principles of radiation protection.
To the various
bid ies
national protection,cownctts is left the responsibility for introducing the detailed technical regulations, recommendations, or codes
of practice best suited to their countries.
Recommendations are in-
tended to guide the experts responsible for radiation protection
practice.
ICRP states that the objectives of radiation protection are to prevent acute radiation effects and to limit the risks of late effects
to an acceptable level.
It holds that it is unknown whether a threshold
exists, and it is assumalthat even the smallesc doses involve a proportionately small risk.
No practical alternative was found to assuming
a linear relationship between dose and effect.
This implies that there
is no wholly "safe" dose of radiation.
Exposure to natural background radiation carries a probability of
causing some somatic or hereditary injury.
However,
the Commission
believes that the risk resulting from exposures received from natural
background should not affect the justification of an additional risk
