Dependence of concentration of radon on environmental parameters

Radon (222Ra) is a colourless and odourless natural radioactive element in gaseous state. The concentration of radon the air usually low, but it can be very high inside living space, because its possibility to penetrate from foundation soil over basement into building itself. People are daily exposed certain that found soil, water, food. This paper shows correlation analysis environmental parameters by using model multiple regressions. It defines statistical relations between such as temperature, humidity, atmospheric pressure with measured values concentrations. Measurements were carried out at several locations various residential buildings north-western Croatia. results indicated individual connected. For example, one location was decreasing if increasing. another increasing humidity Due large number different affecting buildings, satisfactory predict not easy achieve since observed variability concentrations within local sites. necessary consider longer period determine certainty mathematical would give most accurate prediction dependence on which affect human health quality life.
