Investigation the radiation effects of natural-enriched uanium hexafluoride (UF6) gas leakage by RASCAL software simulation

Abstract

Background: Radioactive release materials in nuclear facilities causes environmental pollution, and absorption of radiations by respiration by people and staff in the area of the accident is a vital problem. The aim of this study was to stimulate the event using Radiological assessment system for consequence analysis (RASCAL) software and compare the results with those of Gaussian experimental model. Methods: In this study, the accident included Uanium hexafluoride (UF6) gas leakage in the environment from the storage areas of the Sooreh Company, Isfahan, Iran. The geographical distribution of radioactive material and the received amount of staff and people around the site were estimated at a radius of ten kilometers. Findings: Uranium hexafluoride gas leakage event had the highest amount of radioactivity release that caused absorbed dose to people and staff in the company fence line. Conclusion: Findings showed that Uranium hexafluoride would not threaten any deterministic effects on staff and people. Also, it is recommended to use software codes to calculate event and radiation risk. © 2021 Isfahan University of Medical Sciences(IUMS). All rights reserved.
