Following a continuous intake of tritium (T) by laying hens' over a 55 day period, an increase of НТО concentration both in eggs and meat was observed over the first 2 weeks for intakes via inhalation and ingestion of water and grass meal. After this time, equilibrium of the T in these products occurred. It was found that when the intake of HTO is from water, air and grass meal, the ratio of its activity concentration in muscular tissue to that in eggs does not exceed 1, 4, and 6 respectively. The ratio of ОBТ concentration to that of НТО in the meat of hens (ОBТ/HTO) when intakes were from water, air and grass meal were 0.08, 0.09 and 0.7, respectively.
