title: [Chronic irradiation with low doses can be characterized by significant biological efficacy].
abstract: Chromosomal aberrations (ChA) level was analyzed in the onion root meristem after the chronic irradiation with different dose capacities. It was shown that after the chronic irradiation with doses of 0.87 cGy, 2.61 cGy and 4.35 cGy the level of chromosomal aberrations depended on the dose capacity. Its value may also correspond to those which have been induced with accute irradiation. Biological efficacy of chronic irradiation may be from 20 to 1000 time folder in order to compare it with accute irradiation and this value depends on the irradiation regime.
