Measurement and Evaluation of Indoor Radon Concentration in a Campus in Shenbei District

摘要

The radon concerchitntration in the classroom, dormitory, laboratory and recording room of a campus in Shenbei was measured and calculated by the FT648 radon measuring instrument. The results show that the levels of radon concentration in a student dormitory and classroom were lower than national limitation of radon concentration. However, radon concentration levels of student laboratory and studio are generally higher than 200 Bq/m~3, the measurement value of radon concentration in laboratory would be higher than national dose limit. It will adversely affect the health of students. In this regard, a proposal to monitor the radon concentration in the laboratory in a long-term is given and the suggestions about precaution and decrease it is taken.
