According to the executive decree of the Atomic law (1996) the action level in workplaces is 1000 B/m3 yearly average radon level in the air. The radon concentration in underground workplaces can be especially high. The difficulties of determination of radon concentration were investigated in the hospital cave of Tapolca where the monthly average was between 0,51 and 12,4 kBq/m3. Considering the dose contribution of the workers it can cause 50% miscalculation that the equilibration factor differs ±50% from the assumed 0,4 value in underground places (caves, mines, etc.).
