Abstract: Radon can accumulate in underground areas, such as in show caves. Therefore, workers, tourist guides may be exposed to significant radiation dose in most of the show caves. It is necessary to measure the radon concentration in order to estimate the exact radiation dose caused by radon. Usually the radon concentration of the caves shows significant seasonal fluctuation, therefore, in order to determine it, this study work involved nine show caves visitable for the public in Hungary, where monthly changes of radon concentration had been studied for one year. Despite the fact that all of the caves formed in karst rocks, the annual average radon concentration levels were rather differing (541-8287 Bq•m-3). We measured the monthly average radon concentration in working hours with personal radon detector too and estimated the dose of the tourist guides. The committed effective dose of workers calculated from the yearly average radon concentration of cave, supposing 2000 hour/year working time and 0,4 equilibrium factor, is 3.4 – 52.2 mSv/year, the real yearly effective dose of tourist guides in the studied show caves which was calculated based on personal dosimetry is 0.3 – 31.2 mSv/year. Keywords: radon, show cave, radiation dose, dose estimation |
