Abstract

Radon (222Ra) is a colourless and odourless natural radioactive element in gaseous state. The concentration of radon in the air is usually low, but it can be very high inside of a living space, because of its possibility to penetrate from a foundation soil over a basement into a building itself. People are daily exposed to a certain concentration of radon that is found in soil, water, air and food. This paper shows a correlation analysis of environmental parameters by using the model of multiple regressions. It defines certain statistical relations between environmental parameters such as temperature, humidity, and atmospheric pressure with measured values of radon concentrations. Measurements were carried out at several locations in various residential buildings in north-western Croatia. The results indicated that individual environmental parameters and radon concentration at individual locations were connected. For example, at one location the concentration of radon was decreasing if atmospheric pressure was increasing. Measurements at another location indicated that the concentration of radon was increasing if air humidity was increasing. Due to large number of different parameters affecting the concentration of radon in residential buildings, a satisfactory statistical model to predict the concentration of radon with environmental parameters is not easy to achieve since it was observed variability of radon concentrations with environmental parameters within different local sites. It is necessary to consider a longer period to determine with certainty a mathematical model that would give the most accurate prediction of radon concentration dependence on environmental parameters which can affect human health and quality of life.
氡浓度对环境参数的依赖性
氡(222Ra)是一种无色无味的天然气态放射性元素。氡在空气中的浓度通常很低,但在居住空间内的浓度可能很高,因为它有可能从地下室的地基土壤渗透到建筑物本身。人们每天都接触到一定浓度的氡,这些氡存在于土壤、水、空气和食物中。本文利用多元回归模型对环境参数进行了相关性分析。它确定了温度、湿度和大气压力等环境参数与氡浓度测量值之间的某些统计关系。测量是在克罗地亚西北部不同住宅建筑的几个地点进行的。结果表明,个别环境参数与个别地点氡浓度之间存在一定的联系。例如,在一个地点,如果大气压力增加,氡的浓度就会下降。在另一个地点的测量表明,如果空气湿度增加,氡的浓度也会增加。由于影响居民楼氡浓度的参数众多,不同地点的氡浓度随环境参数的变化存在差异,因此很难建立一个令人满意的统计模型来预测环境参数对氡浓度的影响。有必要考虑较长时期,以确定一种数学模型,以最准确地预测氡浓度对可能影响人类健康和生活质量的环境参数的依赖。
