"Breeding stock of the CFW strain of mouse was obtained from

the Coronet Laboratories of Shawnee Mission, Kansas. Virgin females were permitted

to mate when 35-45 days of age in the ratio of four females per male per breeding

cage. Time of conception, given later confirmation of gravidity, was assumed to be

the night preceding early-morning verification of a vaginal plug of sperm, according

to the rationale of Kalter ( 1968 l . Environment.) All radiation treatments were administered between 7 AM andIO AM. Ambient temperature in the colony and in the laboratory averaged 23 C. Relative

humidity ranged between 50 and 75%. Forced air at the ambient temperature flowed

through the cavity at an averaged lineal velocity of 0.1 m/sec. While in their living

cages, dams and their offspring had continuous access to water and to Purina Lab

Chow."
