Abstract

The microclimate in the hospital cave of Tapolca has medical benefit in the cases of respiratory diseases. But, as it is known, high radon levels are expected in underground places such as caves. The radon concentration was measured continuously in the cave mentioned above for three years. The equilibrium factor between the radon and its daughters was also determined in different seasons and the dose contributions for the patients and staff were assessed. The radon level showed significant change with seasons; in wintertime it was low (average: 0.7 kBq/m3) and in summertime it reached relatively high values (average: 11.5 kBq/m3). The determined equilibrium factor (0.6) was 50% higher than the theoretically expected value, consequently this means higher dose contribution. The patients get 0.18-4.22 mSv dose during a treating period depending on the season of the cure. A member of the staff can get 22 mSv in a year that exceeds the dose limit for workers. The conventional methods to mitigate the radon level are not acceptable in this case, so for the reducing of the dose contribution other ways should be found (for example to reduce the effective working time of staff).
