[Comparative study of chromosome aberration formation in lymphocytes culture under pulsed and continuous neutron irradiation].
Frequencies of chromosome aberration induced by prolong (continuous) neutron radiation (dose-rate 0.17 Gy/min) and pulsed neutron radiation with ultra-high dose-rate (1-4) x 10(5) Gy/s have been studied in human blood lymphocytes at G0-stage. It was demonstrated that cytogenetic efficiency of pulsed neutrons (after the substraction of approximately 50% gamma-component from the total dose) was 2 times higher than that of continuous neutron radiation.
