| 内容記述 | A preliminary study of radon concentration and air-quality parameters in Hungarian workplaces revealed that using the same dose conversion factor (7.9 nSv m3 Bq-1 h-1 recommended by ICRP) – e.g. in case of a deep mine and a medicinal bath – may considerably reduce the reliability of the estimated dose. In order to gain more information related to this dose estimation problem, it was necessary to measure radon and its short-lived progenies concentrations; the unattached fraction of radon short-lived progenies; the equilibrium factor; along with temperature and the relative humidity not only in a medicinal bath (14 days) but also in a tourist cave (7 days), in a medicinal cave (7 days), in a manganese deep mine (9 days) and in a deep geological radioactive waste depository under construction (7 days) in Hungary. With the above data obtained, new specific dose conversion factors were determined taking respiration through the nose and through the mouth into consideration. Calculating with the annual labour hours related to each workplace, the effective dose of the workers was estimated. For the radon medicinal bath, the calculated dose conversion factors, distinguished nose and mouth respiration, were lower than the recommended 7.9 nSv m3 Bq-1 h-1, respectively. For the tourist cave, the medicinal cave, the manganese deep mine and the deep geological radioactive waste depository, the dose conversion factors were higher than the recommended one causing significant differences in dose estimation. |
