Measurements of cesium-137 internal decontamination

In the accident with Cs 137 which took place in Goiania, it could be verified that the majority of the victims presented internal and external contamination. In order to minimize deposits in internal organs and tissues and to enhance the excretion of Cs 137 we started treating the patients with: (1) Prussian Blue, oral administration, in about 46 patients, (2) Diuretics, oral administration, in 17 patients, and (3) Increasing the Cs 137 elimination by the sweat. Those proceedings were done under rigourous clinical evaluation and with data from radiochemical assay of excreta and afterwards with data obtained through the ''in vivo'' analysis though Whole Body Counting (Body Burden).
