Abstract

Protection against ionizing radiations is important in laboratories with radioactive materials and high energy cyclotron beams. The Cyclotron and Radioisotope Center (CYRIC) located in Tohoku University in Miyagi prefecture, Japan and is a well-known nuclear science laboratory with cyclotron beams and substantial number of high activity radioactive materials. Considering this, it is important to perform complete radiation transport computations to ensure the safety of non-occupational and occupational workers. In the present work, we have developed a complete 3-dimensional model of the main cyclotron building and radiation labs using Monte Carlo method. We have found that the dispersed photons and neutrons inside and in the surrounding of the CYRIC building pose no significant risk to occupational and non-occupational workers. The present work and the developed models would be useful in the field of radiation protection.

东北大学回旋加速器和放射性同位素中心(CYRIC)的蒙特卡罗建模:辐射防护研究。
在使用放射性材料和高能回旋加速器束的实验室中,电离辐射防护非常重要。位于日本宫城县东北大学的回旋加速器和放射性同位素中心(CYRIC)是一个著名的核科学实验室,拥有回旋加速器束和大量高活性放射性物质。有鉴于此,进行完整的辐射输运计算对确保非职业和职业工作人员的安全非常重要。在本研究中,我们采用蒙特卡洛方法建立了回旋加速器主楼和辐射实验室的完整三维模型。我们发现,CYRIC 大楼内部和周围分散的光子和中子不会对职业和非职业工作人员造成重大风险。目前的工作和开发的模型将对辐射防护领域有所帮助。

期刊介绍: Journal of Radiological Protection publishes articles on all aspects of radiological protection, including non-ionising as well as ionising radiations. Fields of interest range from research, development and theory to operational matters, education and training. The very wide spectrum of its topics includes: dosimetry, instrument development, specialized measuring techniques, epidemiology, biological effects (in vivo and in vitro) and risk and environmental impact assessments. The journal encourages publication of data and code as well as results.
