EVOLUTION OF THE ICRP SYSTEM
Dr Hylton SMITH
Biochemist, Former Scientific Secretary of ICRP
The biological bases of radiological protection have evolved
over the past hundred years from the view that ionising radiations were
harmless to the point where it is generally accepted that health detriment,
expressed as radiation-induced cancers and serious hereditary effects,
is proportional to the dose received without a threshold. The primary aim
is to provide an appropriate standard of protection for man without unduly
limiting the beneficial practices giving rise to radiation exposure.
2. A skin tolerance dose for acute effects
3. From tolerance dose to maximum permissible
4. From maximum permissible dose to acceptable
5. A system of dose limitation for practices.
6. A system of protection for practices
and for intervention.
7. Concluding remarks.
