Abstract

Radon develops from the radioactive decay of radium and has a half-life of 3.8 days. This gas seeps through soil into buildings, and if it is not evacuated, there can be much higher exposure levels indoors than outdoors, which is where human exposure occurs. In this way, radon affects occupants through the indoor climate.

The World Health Organization recommends states to introduce requirements for the maximum concentration of radiation from natural sources in the indoor air. These recommendations are the result of the World Health Organization's evaluation of radon as being responsible for 3-14% of lung cancer incidents, depending on the average radon exposure in different countries. Results show radon to be the second-largest cause of lung cancer (tobacco smoking is still the primary cause). Radon exposure must be taken seriously in the struggle against radon-induced lung cancer due to the large number of people who are exposed daily in buildings and especially in residential buildings. In this study, radon levels in rented accommodation located in multi-occupant houses and single-family terraced houses were measured in two following winter periods. Homes are located in buildings recorded as being constructed before 2010 and after the year 1850. The paper shows how well 221 of these homes perform, with respect to the recommendations given by the World Health Organization regard to radon, and to identifying the association between indoor radon levels and floor level, multi-occupant houses, single-family terraced houses, and basements. The mean year value and the number of homes with radon levels exceeding 100 and 200 Bq/m3 will be determined.
