title: Changes in the recovery ability of colony-forming units after continuous irradiation.
abstract: The recovery ability of colony-forming units from mice continuously irradiated for 30 and 100 days at an exposure rate of 25 and 50R/day was investigated. The rate of recovery depended not only on the daily exposure but also on the total dose accumulated. The course of the recovery process was assumed as follows: B(t) = Bs + (Bo--Bs). (formula:see text) was characterized by calculating the estimate(s) of the recovery coefficient tau.
