CYTOGENETIC BIODOSIMETRY OF ACCIDENTAL EXPOSURES IN THE LONG TERMS AFTER IRRADIATION.

abstract：:The theoretical basis for comparing risks from short- and long-term exposures is developed aiming at implementing long-term exposures into a unique and consistent system of radiation protection. Based on system-analytical considerations, the equivalence of population-averaged risk rates due to prolonged exposures and ...
