[Dosimetric measurements and early complications in patients with differentiated thyroid carcinomas treated with...

The aim of the study was to determine the exposure dose rate during the application of radioiodine therapy (ablative or tumoral dose) given in order to treat the differentiated thyroid carcinoma, during the medical visit and examinations of those patients, to establish the safety distance from patients both for population and for medical staff and to perceive early complications after the therapy. The dosimetric measurements were performed in 10 patients. The exposure dose rate during the application of the therapy ranged from 2000 to 10000 pC/kg.s, during the visit from 528 to 15 pC/kg.s and during the examinations of patients from 5500 to 200 pC/kg.s. The average safety distance from patients for population was about 8.5 m on the day O (the very day of the therapy) and 2.0 m on the day 4, while for the medical staff it amounted to 5.0 m on the day 0 and 0.5 m on the day 4. The early complications perceived were as follows: radiation thyroiditis in 5/10 patients, stomach problems in 1/10 patients and transitorial leucopeny, forty days after the therapy, in 2/10 patients.
