Abstract

Humans are daily exposed to natural background radiations. These are from terrestrial, extra-terrestrial, and anthropogenic radiation sources. Soil is one of the largest contributors to terrestrial radioactivity. The aim of this research was to assess the concentrations of the primordial radionuclides uranium (²³⁸U), thorium (²³²Th) and potassium (⁴⁰K) as well as radiological hazard parameters in soil samples selected from Al-Salam playground in Al-Najaf governorate of Iraq. Gamma ray spectroscopy and a CR-39 detector were used to evaluate both external exposure and internal exposures arising from radon concentrations, respectively. The average activity concentration (Bq kg^-1) for ²³⁸U, ²³²Th, and ⁴⁰K were 17.48 ± 1.89, 8.59 ± 0.77, and 298.31 ± 18.40, respectively. Quantified radiological risk factors were 116.23 ± 5.76 µR h^-1 (exposure), 0.142 ± 0.007 (external hazard (H_ex), 25.71 ± 1.28 nGy h^-1 (absorbed dose rate (D_r), 0.031 ± 0.001 (annual effective dose outdoor (AED_outdoor), and 0.110 ± 0.005 (cancer risk (ELCR × 10^-3), respectively. It was concluded that all values of the activity concentration for natural radionuclides and radiological hazard parameters in study area were within safe limits based on standards set by UNSCEAR, ICRP, and OECD.

对伊拉克纳杰夫省Al-Salam游乐场土壤样本的天然放射性进行评估。

人类每天都暴露在自然本底辐射中。这些辐射来自地球、地外和人为辐射源。土壤是陆地放射性的最大贡献者之一。本研究的目的是评估从伊拉克Al-Najaf省Al-Salam游乐场选取的土壤样品中原始放射性核素铀（238U）、钍（232Th）和钾（40K）的浓度以及放射性危害参数。伽马射线光谱学和CR-39探测器分别用于评估氡浓度引起的外部照射和内部照射。238U、232Th和40K的平均活性浓度（Bq kg-1）分别为17.48±1.89、8.59±0.77和298.31±18.40。量化的放射危险因素分别为116.23±5.76µR h-1（暴露）、0.142±0.007µR h-1（外部危害）、25.71±1.28µR h-1（吸收剂量率）、0.031±0.001（室外年有效剂量）和0.110±0.005（癌症危险）（ELCR × 10-3）。研究区的天然放射性核素活度浓度和辐射危害参数均在联合国核科委、ICRP和经合组织制定的安全限值范围内。

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
