Abstract:
|
The average radon level in Ireland is approximately 89 Bq/m3 placing Ireland as a country with one of the highest radon levels in Europe. It has been estimated that 13% of lung cancer deaths in Ireland are caused by exposure to high levels of radon gas in dwellings. Previous studies of indoor radon levels in the UK have shown that measurements of residential radon are subject to seasonal variation. The standard measurement technique used by the RPII is to place detectors in homes for a three month period. Due to the substantial seasonal variation that occurs in indoor radon levels, it is necessary to seasonally adjust all three-month measurements to allow for accurate estimations of annual radon levels in a given locality. This paper reports on the development of new methodologies to produce, for the first time, seasonal correction factors calculated specifically for Ireland.
