Sažetak
The effective protection of the public against radon requires that the buildings should be safe from the point of view of the radon gas. Radon maps serve as valuable tools in designing effective strategies in the program of protection against indoor radon both for existing and future houses. The goal of our paper is to propose a method for radon mapping which is easy and commonly applicable. The method use mathematical model for calculation of Rn concentration in buildings. The model takes into consideration the physical parameters of the soil and the basement and structures of the buildings. The calculated results were compared to the experimental results measured in the buildings with CR-39. The model was verified through results of the measurements of the radon concentration of the soil gas, the exhalation from the soil and accumulation in the building. The experimental results show that radon content of soil gas, radon exhalation of soil surfaces may vary significantly even in a small area. Therefore sufficiently large number of sampling points should be investigated to obtain representative result for a given geological area. The radon measurements in this study were accompanied with integral gamma dose measurements in environment with four different thermoluminescence (TL) detectors and one radiophotoluminescence (RPL) dosimeter (SC-1). There was no difference between the doses measured within and outside the buildings i.e. the building materials did not influenced the background doses. The measured dose values (0.14-0.16 mGy) corresponded to the natural integral background in the environment for the monitoring period (41 days) on all locations. This study was supported partly by the Hungarian Academy of Sciences (project number 2008/B/20/cs).
