This is the simpler of the two questions. A safe level of radon gas is no radon gas. Radon gas is a carcinogen which causes lung cancer. The US EPA has put it plainly, stating, Any radon exposure has some risk of causing lung cancer.The lower the radon level in your home, the lower your family's risk of lung cancer..hile no level of radon gas is completely safe, as with most things in life we must balance the benefits and costs to find our own acceptable levels. We walk outside and work in the sun, exposing ourselves to ultraviolet radiation and increasing our risk of developing skin cancer.
