Use of Whole-Body Counters in Radiological Protection

Radiological protection of patients

An approach for the efficiency calibration of whole body counters.

An approach is outlined for the evaluation of the efficiency of whole body counters using experimental data for a point source and Monte Carlo simulation of the efficiency of photon arrival at a large volume NaI(Tl) detector. The approach was applied to the measurement of an experimental whole body phantom. The experimental and the predicted efficiencies were found to differ from -2.5% to 8.4%....

Radiation protection properties of Myrtus communis against oxidation caused by whole-body exposure of mice

Introduction: Exposure to ionizing radiation can be through direct hit or water radiolysis lead to oxidation in biological systems. In this study, the protective effect of Myrtus Communis aqueous extract on structural changes and oxidative stress in red blood cells and plasma proteins was examined after receipt of ionizing radiation. Materials and Methods: wis...

Individual Calibration of Whole-body and Partial-body Counters by Means of Voxel Phantoms

accuracy of activity determination by means of whole-body and partial-body counters is no longer determined by errors in counting statistics, but by the bias caused by calibration. This is true in particular of low-energy photon emitters, such as Pb-210, U-235, Th-234 (daughter product of U-238), and Am-241. In addition, these nuclides in general show a very inhomogeneous distribution in the bo...
