ABSTRACT

This study portrays the relationship between Radon activity concentration and physicochemical parameters in groundwater in Erbil city, Iraq. Primary data of groundwater samples were collected from five different zones in Erbil, during February 2019. Water samples were collected for both Radon measurement and physicochemical analysis. Water samples were taken from 24 different wells as a reference, then directly measured their radioactivity at the laboratory of Erbil Environment Office. Dissolved Radon ${\hspace{0.17em}}_{\hspace{0.17em}}^{222}Rn$ in a sampled groundwater has been measured using an electronic Radon detector RAD 7. Determination of various parameters such as $pH$, total dissolved solids, total hardness, Sulfate, and Magnesium in groundwater has also been measured. Moreover, regression analysis illustrated that there is no significant relationship observed between $pH$, $TDS$, and hardness, Sulfate, and Magnesium with Radon activity concentration because these are no significant at the 95% confidence level. Otherwise, the correlation of determinate ($R^2$) values show the relationship between Sulfate and Magnesium with Radon concentration because these are significant at the 95% confidence level. All measurements were done in almost identical environmental conditions to avoid the minor differences in meteorological parameters.

抽象的

这项研究描绘了伊拉克埃尔比勒市地下水中Rad活度浓度与理化参数之间的关系。2019年2月，从Erbil的五个不同区域收集了地下水样品的主要数据。收集了水样品以进行Rad测量和理化分析。从24个不同的井中取水作为参考，然后直接在Erbil环境办公室的实验室中测量其放射性。溶解Rad${\hspace{0.17em}}_{\hspace{0.17em}}^{222}\mathrm{[R}ñ$ 已使用电子Radon探测器RAD 7测量了采样地下水中的水。 $pH$，还测量了地下水中的总溶解固体，总硬度，硫酸盐和镁。此外，回归分析表明，没有观察到明显的相关性。$pH$， $Ťd\mathrm{小号}$，以及具有S活度浓度的硬度，硫酸盐和镁，因为它们在95％置信水平下均不显着。否则，确定的相关性（${\mathrm{[R}}^2$）值显示了硫酸盐和镁与Rad浓度之间的关系，因为它们在95％的置信水平下很显着。所有测量均在几乎相同的环境条件下进行，以避免气象参数的微小差异。
