An overview of time integrated measurements of indoor radon and thoron concentrations in Republic of Macedonia PO-25

Radon, thoron and their decay products are the main sources of public exposure to ionizing radiation in indoor environment in most countries worldwide. Taking into account the health effects and their large scale variability, the investigation of radon and thoron concentrations in living and working environments still affords scientific attention. During last several years, a number of studies related to indoor radon and thoron concentrations in different indoor environments of Republic of Macedonia appeared as well in international literature. This presentation summarized published data and discussed radon and thoron temporal and spatial variability. The analysis of the factors which in uence the concentrations variation is also reported. Apart from discussing this results, this presentation give an overview on the radon and thoron concentrations measured in the neighboring countries, ongoing and plans for further activities
