ABSTRACT
Rats were ingested in drinking water 600mg/L of cadmium chloride solution during 3 months, then the distribution of Cd in major organs and hair were determined by neutron activation analysis. The results were as followings. 1. After administration for 24 hours using $^{115m}Cd$ as tracer, the distribution of blood was 0.03%, kidney 2.99% and liver 3.50% to determine with whole body counter. 2. Cd metal was rapidly excreted with kidney through blood and their accumulation appeared in liver and hair. 3. The comparative data to determine using neutron activation analysis. the content of cadmium of major organs in rats ingested of $CdCl_2$ during 3 month were shown to increase significantly both hair and liver. Above facts, hair samples were able to use as the diagnostic index to evaluate the accumulation of cadmium in liver.
