The Indoor Radon Concentration Measurement and Analysis in a University and its Adjacent Areas

摘要

Radon is a radioactive gas, high concentrations of radon in the environment can cause lung cancer, leukemia and other diseases. In this paper, indoor radon concentration in different places were measured and analyzed by using the RAD-7 radon monitor in a university and its adjacent areas. On-site measurements show that within 24 hours the indoor radon concentration versus time has certain regularity, different interior architectural decoration materials has a certain influence on the radon concentration, the radon concentrations in long confined spaces are significantly higher than those places frequently ventilated, floor height and ventilation conditions have a greater impact on the radon concentration. This research can provide a reference for future prevention and control of radon hazards.
