Abstract
Radon and its short lived decay products accumulated in indoor environment are the main source of public exposure to natural radiations. The health effects as well as a great number of natural and artificial factors affecting the radon accumulation in indoor environments are some of the motives for the scientific interest in radon issue. Following this global trend, many studies of indoor radon in the Balkan region, including the Republic of Macedonia have been conducted in the last decade. This paper is an overview of the published papers regarding indoor radon concentration measurements with nuclear track detectors in the Republic of Macedonia. It gives basic information about the spatial and temporal variability of indoor radon over the territory of the country, following by a description of the some factors which affect its variations. This review attempts: to organize available indoor radon results in order to show clear picture of the so far conducted surveys; to highlight the need for continuation of more extensive radon investigation in workplaces; to motivate the building professionals to create as much as possible mitigation methods for indoor radon reduction, to motivate the health professionals for epidemiological studies etc.
Highlights
Radon (222Rn) is a radioactive, noble gas produced by the decay of 226Ra contained in all terrestrial materials
This study summarized the results of indoor radon concentrations (CRn) in the Republic of Macedonia published in the literature
The maximum value of 720 Bq/m3 reported for S1 survey was measured in Pelagonia statistical region (Stojanovska et al, 2011a;)
Summary
Radon (222Rn) is a radioactive, noble gas produced by the decay of 226Ra contained in all terrestrial materials. Both of them originate from 238U decay chain. Radon and its decay products accumulated in indoor environment are the main natural source of total public exposure to ionizing radiation (UNSCEAR, 2000). Some epidemiological studies have proven the association between the chronic exposure to high indoor radon concentrations (CRn) and the incidence of lung cancer (Darby et al, 2005). Its preparation requires a multidisciplinary approach conditioned by the understanding of the radon processes in indoor environment
