基于换气量和氡析出率计算的排氡风量在某水电地下工程通风设计中的比较研究

Abstract

Abstract: Taking a hydropower underground engineering project as an example, the air volume of radon reduction had been calculated according to the ventilation volume and radon emanation quantity. The result showed that the air flow could be reviewed according to the radon emanation quantity when the increment of underground radon concentration was greater than 200 Bq/(m³·h). Otherwise, the air flow could be reviewed on the basis of the ventilation volume. This method provided technical supports for the design of underground hydropower engineering.

Key words: hydropower underground engineering, radon emanation quantity, dehumidification and hypothermia, ventilation rate
