Background. Radon is a colourless, odourless, radioactive gas that occurs naturally in the environment. It comes from the natural breakdown of uranium, and can be found in high concentrations where soils and rocks contain uranium, granite, shale, or phosphate.t should also be mentioned that homes that experience readings of high levels of radon gas, can be rectified. There are numerous remedial actions that offer excellent solutions to sealing homes to radon gas as well as diverting or venting solutions. Costs may vary but generally range from $2500 - $5000 for remediation.
