| Summary: | Monte Carlo simulations and dose measurements were performed for
radionuclides in the whole body and trunks of different sizes in order to
estimate external radiation whole body doses from patients administered with
radiopharmaceuticals. Calculations were performed on cylindrical water
phantoms whose height was 176 cm and for three body diameters: of 24 cm, 30
cm, and 36 cm. The investigated radionuclides were: 99mTc, 131I, 23I, 67Ga,
201Tl, and 111In. Measured and MCNP-calculated values were 2-6 times lower
than the values calculated by the point source method. Additionaly, the total
dose received by the public until a radionuclide is completely disintegrated
was calculated. The other purpose of this work is to provide data on whole
body and finger occupational doses received by technologists working in
nuclear medicine. Data showed a wide variation in doses that depended on the
individual technologist and the position of the dosimeter.
