-95- ing (see Table 1), AECD-3446 The counts found in bone samples werethe highest of trated by the three specimens from Engebi, Rat 1 was collected in an area h registered 37,000 c/m on a Victoreen #263 survey meter and had a bone t of 1780 d/m/g. Rat, and Rat, were collected at another site only 650 feet hat of Rat, 1n an area which registered 600 c/m on the same meter, Their ‘counts were respectively 163 d/m/g and 153 d/m/g. The counts found in the liver samples of the rats were relatively low in parison to those of the alimentary tract and the bone samples, The amount Fadioactivity in the digestive tract was variable although in all cases the animals dnot eaten contaminated food for at least twelve hours before being killed. In lung and kidney samples, counts were found only in Rat, from Engebi These were 25 d/m/g and 312 d/m/g, respectively. * The determination of d/m/g of total body weight (see Table 1) was computed “the percent of total body weight for each organ. The amount of radioactivity ram of total animal was correlated somewhat with the amount of radioactivity area of trapping. Rat, from Engebi had 116 d/m/g of total animal and was in an area which registered 37,000 c/m on a Victoreen-type #263 meter. ' ;and Rat, from the sameisland, had 15. 2 and 10.7 d/m /g respectively of al animal and were trapped in an area which registered 600 c /m on the survey The rat from Biijiri had .6 d/m/g of total animal and was caught in an which registered 140 c/m on the meter, .The organs selected make up 33 per cent of the total body weight since e, nervous tissue, blood, spleen, pancreas, heart, and connective tissue than bone was not sampled. r The non-sampled tissues were considered to be ctivity and hence the d/m/g of total body weight is a minimum value. rte Teves an fa rwiy, BE _
