Resumo
In the attempt of a quality life improvement, the use of the nuclear technology is increasing
everywhere, fact observed in the increasing use of radioisotopes and radiopharmaceuticals in nuclear medicine
diagnosis and therapy. In the radiopharmaceutical facility of “Instituto de Pesquisas Energéticas e Nucleares,
IPEN,” the productions have had an increase of about 10% per year since the decade of 80. Actually about 20
radiopharmaceuticals are produced and in 2007 approximately 43441 bulks had been distributed that totalized an
activity of 723.16 TBq. The main radioisotope produced is the metastable technetium (99mTc) generated from the
molybdenum (99Mo) in a portable generating system. This radioisotope has contributed with 88.54% of the
activity produced in 2007 and is important in the nuclear medicine diagnosis because the little gamma rays
energy present a small dose to be detectable by external detector. The relatively short physical and effective halflife, become it easy to be transported and can obtained at relatively low price. The 99mTc generator is produced
weekly. Initially the 99Mo is received and inserted in processing cells, after that it is chemical processed, divided
and placed in columns. After these the columns containing the 99Mo are inserted in lead containers and these are
placed in packages for delivery. The assembly procedures for 99mTc generator are the major source of radiation
exposure to Radiopharmaceutical Facility personnel. This paper has the purpose to analyze the effective doses of
workers in the phases of production of 99mTc generators. Will be presented the annual effective doses of workers
involved with the facility. The obtained results provide valuable information about radiation protection.
