Accidents at reactors, including the Chernobyl accident, resulted in far more stringent criteria of protection from the effects of ionising radiation, but, as was later found, those effects proved to be much less significant than had been predicted.
Accidentele la reactoare, inclusiv accidentul de la Cernobîl, au condus la înăsprirea criteriilor de protecție împotriva efectelor radiațiilor ionizante, dar, după cum s-a descoperit ulterior, aceste efecte s-au dovedit a fi mai puțin semnificative decât se prevăzuse.
