In view of the international maximum permissible dose of radiations of 0.05 rep psr 24 hr, an appraisal was made of the usual doses of I/sup 131/ used in peirforming thyroid function tests in children (1 mu c per kg of body weight). On the basis of the physical characteristics of I/sup 31/i and of anatomithcal and functional data concenning the thyroid gland in children, it was concluded that tests with radiolodine, as usually performed. are a cause of much greater irradiation of the gland than the permissible degree of irradiation based on the above tolerable dose. In order to avi~d excessive irradiation, the use of an iodine isotope with a shorter half-life (I/sup 132/ was considered. The results of personal studies contact with the techique were presented. Owing to the improvements in measuring apparatus, values for the uptake and urinary excretion of I/sup 131/ were obtained with this technique which were in agreement with previous researches in this field using a total dose of 0.2 to 0.3 mu c in children aged 5 to 11 years.
