Abstract

The present study focused on the monthly or annual 41Ar activity release rate and ground level activity concentration measurement including the estimation of public dose level at the ground and stack positions of the Bangladesh Atomic Energy Commission TRIGA Research. During the experimental work, a Geiger-Muller (G-M) counter was used for the air sample count rate study. The experimental results demonstrated that the obtained maximum monthly or annual 41Ar activity release rate (2.48 × 1010 Bq/month or 6.25 × 1011 Bq/year) and monthly maximum ground level 41Ar activity concentration (6.40 × 101 Bq/m3) were within the permissible limits set by the regulatory body. This report also confirmed that the estimated public dose levels (0.29 mSv/yr and 0.0002 mSv/yr) at the stack and ground positions were far below the IAEA acceptable limit (1.0 mSv/yr) which was significant for the research reactor safety.

孟加拉国原子能委员会TRIGA研究堆41Ar活性释放率的实验研究

本研究的重点是每月或每年41Ar放射性释放率和地面放射性浓度测量，包括孟加拉国原子能委员会TRIGA研究所地面和烟囱位置的公共剂量水平估计。在实验工作中，使用盖革-穆勒（G-M）计数器进行空气样本计数率研究。实验结果表明，所获得的最大月或年41Ar活度释放率（2.48×1010Bq/月或6.25×1011Bq/年）和月最大地面41Ar活性浓度（6.40×101Bq/m3）均在监管机构设定的允许范围内。该报告还证实，堆和地面位置的公共剂量水平估计值（0.29 mSv/yr和0.0002 mSv/yr）远低于原子能机构可接受的限值（1.0 mSv/yr），这对研究反应堆安全意义重大。

期刊介绍： Today, nuclear reactors generate nearly one quarter of the electricity in nations representing two thirds of humanity, and other nuclear applications are integral to many aspects of the world economy. Nuclear fission remains an important option for meeting energy requirements and maintaining a balanced worldwide energy policy; with major countries expanding nuclear energy"s role and new countries poised to introduce it, the key issue is not whether the use of nuclear technology will grow worldwide, even if public opinion concerning safety, the economics of nuclear power, and waste disposal issues adversely affect the general acceptance of nuclear power, but whether it will grow fast enough to make a decisive contribution to the global imperative of sustainable development.
