| 要約: | In order to address concern about radon exhalation in building material,
radon exhalation rate was determined for different granites available on
Serbian market. Radon exhalation rate, along with mass exhalation rate and
effective radium content were determined by closed chamber method and active
continuous radon measurement technique. For this research, special chambers
were made and tested for back diffusion and leakage, and the radon
concentrations measured were included in the calculation of radon exhalation.
The radon exhalation rate ranged from 0.161 Bq/m2h to 0.576 Bq/m2h, the mass
exhalation rate from 0.167 Bq/kgh to 0.678 Bq/kgh, while the effective radium
content was found to be from 12.37 Bq/kg to 50.23 Bq/kg. The results indicate
that the granites used in Serbia have a low level of radon exhalation. |
