Description

The experiment feeding 90Sr(NO3)2 in the range of 1.85 x 102 to 1.85 x 105 Bq/chicken was carried out with 45 Beijing-white layers to observe the regular pattern of absorption and distribution of 90Sr in organs and tissues. The results are summarized as follows: the uptake rate of 90Sr by layer through oral feeding is very low. Most part of 90Sr drains away from body with daily excreta and egg. The accumulation of 90Sr in the body is low and about 70% is in the bone. About 99% of 90Sr in egg is concentrated in the eggshell. The order of absorptivity of 90Sr in tissues is bone>feather>muscle>blood>viscera. The absorption coefficient of 90Sr in organs and tissues in different stages with different feeding volumes has been calculated
