Annual Effective Dose of Gamma Ray for Radiological Workers in Radiation Measurements Labs

Abstract

Ionizing radiation is harmful to human health so safety has been studied by many researchers. All these efforts are to minimize causes deterministic health effects of radiation. The radiation risks that arise from the use of radioactive sources on workers, in the field of radiation applications, and in the environment have to be assessed. Absorbed dose and Annual effective dose of gamma rays in the body were measured for workers in one of the laboratories dealing with gamma radioactive sources. The six gamma radioactive sources and Portable sodium iodide were used in this study. The average level of accumulated Annual effective dose value received from the used radioactive sources was extended from 0.422 to 5.56 mSv.y-1 In addition to this, using risk factors indicates a very low probability of cancer injury for workers which refers to safe conditions work environment with these kinds of labs.
