Regulation of exposure for the twenty-first century

Last ICRP recommendations of the regulation of the people radiation exposure is the subject of well founded criticism. Use of the linear no-threshold dose functions by restriction of stochastic effects is in centre of attention. Theoretical and empirical basis of that hypothesis is examined and is shown to be not flawless. New knowledge indicatives: more than one half of all human radiation cancers at low dose rate are following the functions with the thresholds from 0.3 to tens of sievert. So long as linear no-threshold model is no more right, the whole today regulation system of the radiation exposure falls in. It is unnecessary to be afraid of low dose irradiations. It is unnecessary to optimize their. One should not use collective and effective doses. None of hereditary effects of human irradiation was revealed in half a century. Therefore it should take into account. Regulation system of the radiation exposure must be better submitted with other risks in human life. It is reasonable to base it on the principle not to exceed the limit lifespan individual dose taking into account dose thresholds. This limits must be equal 2.5 Sv for personal and 0.5 Sv for population. New quantities are proposed gamma-dose and weighted dose. Parallel with the committed equivalent dose it must regulate the content in organism of radioactive substances
