| Abstract: | The radon activity concentration was measured in 67 rooms in kindergartens in Visegrad countries over a period of 1 year using the SSNTD method within the framework of the standard V4 project. In 7.5% of rooms radon activity concentration exceeded 300 Bq m?3, the reference value recommended by the Council Directive 2013/59/EURATOM. The annual effective doses due to radon inhalation ranged from 0.5 to 13.3 mSv for children and from 0.3 to 8.3 mSv for staff. |
