It should be emphasised that even though we were, until 50 yeacs ago, unavare of it, that all animals and all men and all other living forme have from even the remotest times been subjected to these low levels of radiation, and ap- parently there is adequate immmity built into these living forms to protect them from injury and to allow them to continue to exist indefinitely although continuously ir- radiated by a few hundred ur/yrthe largest Three successive levels of radiation dose rate have been mentioned, ich, the ore established as safe for vorkers in the radiation indus- try ty the NCRP, produces no observable biological effect. a
