THE INFLUENCE OF A SINGLE DOSE OF I131 ON THE RETENTION AND DISTRIBUTION OF I131 IN THE RAT

摘要

This report describes a detailed investigation of the distribution and re¬tention of a single massive dose of r131, 50 pc/g body weight, in the young adult female rat. These studies were undertaken to (a) determine the influence of the intense beta-particle radiation on the time-course of distribution of r131 in the tissues, (b) to estimate more precisely the amount of radiation absorbed in the tissues that exhibited acute and(or) chronic pathological changes, and (c) to shed some light on the modes of acute lethal action of I131.
