This research investigated the health risk to workers from radon in selected B.C. workplaces. The information gained will be used to develop a full research proposal aimed to formulate guidance for new policy and regulatory requirements in relation to radon entry prevention, and limited radon exposure, in the workplace

The researchers assessed the extent to which radon, a naturally occurring radioactive gas, is a health risk in B.C. workplaces. Radon monitoring data was used to estimate the annual radiation doses that would result from radon in a variety of workplaces. The estimated doses were then compared with the Action Level and maximum Annual Effective Dose specified for ionizing radiation in BC Occupational Health and Safety Regulation. The project also obtained new radon monitoring data from a small selection of workplaces such as show caves and facilities located in radon-prone areas of B.C., and examined the available literature on radon in the workplace

Based on the findings, recommendations are provided for workplace radon prevention, protection, monitoring, and regulatory issues in B.C
