RESUMO
In a laboratory in a company manufacturing radiopharmaceuticals, a laboratory technician was contaminated with I. The employee was preparing I capsules for thyroid carcinoma treatment. The employee was wearing two pairs of protective gloves and, when changing gloves, noticed a rupture in the right inner glove but no visible rupture in the outer glove. Only 3-4 h later, routine monitoring revealed heavy contamination of the back of the right hand. Immediate actions to decontaminate the hand were taken on-site. Stable iodine was not administered. On the next day, besides persisting heavy contamination of the hand, I was also detected in the thyroid gland. Based on original measurements on-site and later follow-up at STUK, including surface contamination measurements and whole body counting, the original I activity on the hand was estimated at 12 MBq and the superficial skin dose at 33 Gy, affecting a skin area of about 10 cm. The thyroid dose was estimated at 430 mGy. Eleven days after the incident, the skin was dry and slightly desquamated. After 15 d, the skin was intact with no desquamation left. No further signs of skin damage have occurred. Cytogenetic analysis of circulating lymphocytes indicated a slight elevation of chromosomal aberrations.

A short guidebook for medical professionals has been published in Finland, summarizing essential knowledge of radiation accidents, including diagnosis and treatment of radiation injuries. The work was undertaken by the Finnish Radiation and Nuclear Safety Authority (STUK), which is a liaison institution of the World Health Organization Radiation Emergency Medical Preparedness and Assistance Network. The booklet is available in all hospital emergency departments and health care centers throughout the country.
