Computation and Measurement of Absorbed Dose in Bone Due to Beta Particles

Abstract

This work deals with measurements of absorbed dose in bone due to beta-rays using thermoluminescent dosimeters. The calibration of the CaSO₄: Dy dosimeters was performed by immersing them in a solution ⁹⁰Sr-⁹⁰Y. The dose rate was then computed from the known concentration of the solution. Theoretical calculations based on the Monte Carlo method were made for beta-emitting radionuclides contained in small polypropylene tubes. Comparison between the results of measurements and calculations shows that the model designed for Monte Carlo calculation is reasonable.
