radon crawl space 13

A heavy metal badge a friend gave me for luck sits on my desk, but now I wonder if it's adding to the radon crawl space. I bought a test kit last week after hearing that uranium decay can seep up from the ground, especially in basements and crawl spaces. The air down there is stagnant, and the soil underneath might be releasing this odorless, radioactive gas. I placed the monitor near the sump pump, hoping it's just a precaution and not a health hazard waiting under the house.
