Study on advancement of counting using mathematical simulation, in Japanese

Kinase, Sakae

A calibration technique for in vivo counting application using Monte Carlo simulation was developed. To validate the calibration technique by calculations, the response functions and counting efficiencies of a whole-body counter installed in JAERI were evaluated using the simulation and measurements. Consequently, the calculations are in good agreement with the measurements. The uncertainties in body burdens of 137Cs estimated with the whole-body counter were also investigated using the Monte Carlo simulation and measurements. It was found that the uncertainties of body burdens estimated with the whole-body counter are strongly dependent on various sources of uncertainty such as radioactivity distribution within the body and counting statistics.
