There's no need for that simply because it still has no biological effect on the residents. People have been living there with this radiation for thousands of years. There is *some* scientific evidence that background radiation actually has beneficial effect on human body (which would be logical because we evolved with it). In some countries people actually do "radon bathes", one of them Germany which is rather ironic.
