ABSTRACT
Radon is a naturally occurring radioactive gas, and is classified as a Group 1 carcinogen which can cause lung cancer if it enters our body through inhalation. It is found in concrete and building materials, and its danger is increasing as it leaks indoors through cracks in old buildings. Thus, this study analyzed the strength properties of a vermiculite matrix in order to manufacture a radon adsorption board capable of absorbing and reducing radon. As a result of the experiment, the vermiculite matrix showed low strength because of expansion and delamination by heat. The strength also decreased by the porous nature of vermiculite.
