Abstract
Whole-body y counting procedure has been used to study the fate, up to 4 years'' post-injection, of Th232 daughters in 4 volunteer subjects who received intravenous injections of 24 ml Thorotrast. Thoron expired in the breath was measured in 2 subjects yielding 9% of thoron formed. A decreasing rate of excretion of the radium daughters was inferred for the time interval of the study. Calculations are made to show that at least 16% of the thoron formed moves out from its site of origin and that the lung dose from expired thoron, depending on time after injection, and Ra228 build up, may vary from 15 to 45 rems/year.
