Abstract
Under normal dietary conditions, but with varying levels of calcium, radiocalcium was preferentially used over radiostrontium as shown by double tracer studies with growing cockerels (ORbone-diet = 0.6). With laying hens the bone, egg shell and egg yolk showed the expected OR value of 0.5–0.6; the plasma and egg white, however, showed OR values greater than 1, about 1.5. Studies with Cs137 and K42 indicated a nonuniformity of accumulation among tissues. The high Cs*/K* ratios in kidney appeared to result from a comparatively lowered capacity for potassium accumulation.
