Radiation safety analysis of a generic 2 MCi multipurpose gamma irradiator.
This study presents a three-dimensional model of a generic 2 MCi multipurpose gamma irradiator, developed to perform a comprehensive radiation safety analysis based on an existing reference design. Using MCNP and QAD-CGGP codes, the gamma dose rate distribution within the irradiation room was calculated for a 3 MCi Co-60 source board. The objective was to assess the effectiveness of the shielding system in meeting regulatory dose limits for occupational and public exposure. The dose rates in the irradiation room (1011 μSv/h within a 270 cm radius), the very low dose rates above the pool (10-6 μSv/h), and the dose rates in the personnel access lanes (maximum 6.55 μSv/h) all remain below the regulatory limit of 10 μSv/h. The results demonstrate that the facility's design ensures full compliance with regulatory requirements across all zones, including areas routinely accessed by personnel, thereby confirming its adequacy in protecting both workers and the surrounding environment.
期刊介绍：
Applied Radiation and Isotopes provides a high quality medium for the publication of substantial, original and scientific and technological papers on the development and peaceful application of nuclear, radiation and radionuclide techniques in chemistry, physics, biochemistry, biology, medicine, security, engineering and in the earth, planetary and environmental sciences, all including dosimetry. Nuclear techniques are defined in the broadest sense and both experimental and theoretical papers are welcome. They include the development and use of α- and β-particles, X-rays and γ-rays, neutrons and other nuclear particles and radiations from all sources, including radionuclides, synchrotron sources, cyclotrons and reactors and from the natural environment.
The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria.
Papers dealing with radiation processing, i.e., where radiation is used to bring about a biological, chemical or physical change in a material, should be directed to our sister journal Radiation Physics and Chemistry.
