Radon monitoring in a historical building in Košice city, Slovakia – a case study

It is known that the highest contribution to the yearly radiation dose for the population derives from natural radioactivity. About 50% of that is estimated to be caused by exposure to radon (Rn) and its products. Human exposure to indoor Rn is currently considered a relevant research topic, because...

Description
Summary:It is known that the highest contribution to the yearly radiation dose for the population derives from natural radioactivity. About 50% of that is estimated to be caused by exposure to radon (Rn) and its products. Human exposure to indoor Rn is currently considered a relevant research topic, because of the associated epidemiological aspects. This paper aimed at Rn concentration measurement in a selected building in Košice city, Slovakia. The continuous monitoring of indoor radon levels was performed over a period of 40 days. The measured concentrations ranged in a wide interval up to 92 Bq/m 3 . The WHO limit value of 100 Bq/m 3 wasn´t exceeded. Analysing the possible sources, both contributions of radon from the building materials and radon from the soil was observed.
