Abstract

In the present study, the radioactivity levels of water samples collected from the main water supply network in Trabzon province and districts and soil samples taken from the vicinity of the water network were measured. An Alphaguard-PQ2000 radon gas detector was used to determine the seasonal radon gas level in the water samples. An HPGe detector was used to determine the level of radioactivity in soil and water samples. The average concentration of 222Rn in drinking water ranges from 0.56 ± 0.51 to 13.3 ± 5 Bq L-1. In water samples, average gross alpha and gross beta values were measured as 8 ± 1 and 43 ± 1 mBq L-1, respectively. The average concentrations of 238U, 232Th, 137Cs, 40K radionuclides in soil were measured as 51 ± 2, 21 ± 2, 16 ± 1, 28 ± 7 Bq m-3, respectively. The average concentrations of 238U, 232Th, 137Cs, 40K radionuclides in drinking water were measured as 147 ± 5, 25 ± 2, 77 ± 2, 12 ± 2 mBq L-1, respectively. When the radon concentrations for drinking water were examined, it was found that the radon concentration of the three samples was above the limit value (11 Bq L-1) allowed by the US-EPA for drinking water. All other results are below the limit values.

土耳其特拉布宗省供水管网放射性水平测定。
在本研究中,测量了从特拉布宗省和地区的主要供水管网采集的水样和从水网附近采集的土壤样品的放射性水平。采用Alphaguard-PQ2000型氡气检测仪测定水样中的季节性氡气水平。用HPGe探测器测定土壤和水样中的放射性水平。饮用水中222Rn的平均浓度为0.56±0.51 ~ 13.3±5 Bq L-1。在水样中,平均总α和总β值分别为8±1和43±1 mBq L-1。土壤中238U、232Th、137Cs、40K放射性核素平均浓度分别为51±2、21±2、16±1、28±7 Bq m-3。饮用水中238U、232Th、137Cs、40K放射性核素平均浓度分别为147±5、25±2、77±2、12±2 mBq L-1。在对饮用水氡浓度进行检测时,发现三个样品的氡浓度均超过了美国环保局规定的饮用水氡限量(11 Bq L-1)。所有其他结果都低于极限值。

期刊介绍: Isotopes in Environmental and Health Studies provides a unique platform for stable isotope studies in geological and life sciences, with emphasis on ecology. The international journal publishes original research papers, review articles, short communications, and book reviews relating to the following topics: -variations in natural isotope abundance (isotope ecology, isotope biochemistry, isotope hydrology, isotope geology) -stable isotope tracer techniques to follow the fate of certain substances in soil, water, plants, animals and in the human body -isotope effects and tracer theory linked with mathematical modelling -isotope measurement methods and equipment with respect to environmental and health research -diagnostic stable isotope application in medicine and in health studies -environmental sources of ionizing radiation and its effects on all living matter
