Test Bed Installation for Performance Evaluation of Radon Mitigating Materials

Abstract

Radon is a naturally occurring radioactive gas. It originates from the decay of uranium, which is present in small quantities in all rocks and soils. It is colorless, odorless and tasteless and can only be measured using special equipment. Because it is a gas, radon can move freely through the soil enabling it to enter the atmosphere. In this paper, we install the test bed for performance evaluation of radon reduction of a SGM and an ARM. The test bed was set in a concrete structure which consists of eight partition rooms. The bottom side of each room is covered by radon gas soil sampled at nearby open fields. Then, we install SGMs and ARMs on top of the soil to protect the indoor air.
