Abstract:
The paper deals with the results of 2200 measurements of microclimatic parameters (temperature, relative
humidity, air velocity) and 40 measurements of indoor radon concentrations performed within the working area
of the reactor RA of the VINČA Institute of Nuclear Sciences, Belgrade, during a one-year period (1996–1997).
The minimum and maximum values of the effective temperature (ET), relative humidity and air velocity were 11.6
and 21.9°C, 30% and 75%, 0.04 and 0.17 m/s, respectively. The measured annual average indoor radon gas
concentrations at eight sites within the reactor working area were in the range of 84 to 334 Bq/m3.
The estimated annual effective dose record of individual workers absorbed from exposure to radon progeny at
work ranged from 0.40 up to 1.64 mSv with a mean value of 0.97 mSv. The annual collective dose of
the radon-exposed 71 workers amounted up to 0.069 manSv.
