Abstract

The distribution of 82Br-bromide in 15 different organs and tissues of rats has been determined by high-resolution gamma-ray spectrometry and by the scintillation counting technique at different times after the application of Na 82Br, either by subcutaneous injection or by continuous administration in the drinking water. The amount of 82Br-bromide in the various tissues reached its largest uptake within a few hours, and the concentration ratio of 82Br in the tissues to blood remained practically constant between 8 and 396 h after the application. The whole stomach of rats was the only organ of those investigated that had a larger uptake of 82Br than blood. Contrary to some previous findings, the concentration of radiobromide in the thyroid was found not to exceed that in the blood. A remarkably high concentration of 82Br was found in the skin, which represented, because of its large mass, the most abundant depot of bromide in the body of rats. The demonstrated excretion of bromide was mainly renal, at a rate of approximately 5% of the administered dose per 24 h.
