Abstract

The main objective of this study was to determine the levels of radon concentrations in different metro lines in Istanbul. Measurements were conducted in underground stations of five distinct metro lines: M1A, M1B, M3, M4 and M6. Radon activity concentration (RAC) values were determined by means of measurements. The annual effective dose values were calculated for employees on the metro line and for passengers using these lines. The lowest radon concentration was found to be 15 Bq/m³, while the highest was 80 Bq/m³. It has been shown that the effective dose received by individuals from radon irradiation in underground stations does not appear to contribute significantly to the annual average effective dose. The city of Istanbul is characterised by a rugged topography, with some metro stations reaching depths of up to 40 m below ground level. Despite this, the increasing depth of the metro stations did not result in a significant increase in radon concentration.

土耳其伊斯坦布尔地铁站氡浓度测量。

本研究的主要目的是确定伊斯坦布尔不同地铁线路的氡浓度水平。测量是在M1A， M1B, M3， M4和M6五条不同的地铁线路的地铁站进行的。采用测量法测定氡活度浓度（RAC）值。计算了地铁线路上的雇员和使用这些线路的乘客的年有效剂量值。氡浓度最低为15 Bq/m3，最高为80 Bq/m3。已经表明，个人从地下站氡辐照中接受的有效剂量似乎对年平均有效剂量没有显著贡献。伊斯坦布尔市的特点是崎岖的地形，一些地铁站的深度可达地下40米。尽管如此，地铁站深度的增加并没有导致氡浓度的显著增加。

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.
