EVOLUTION OF THE ICRP SYSTEM OF PROTECTION
Dr Hylton SMITH
Biochemist, Former Scientific Secretary of ICRP

Summary
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.
