One thing to be very clear about is the point of the measures done by weatherization, and potentially other programs. These are not radon mitigation programs and budgets are limited. They need to look at issues from a "do no harm" perspective, which is consistent with EPA's Healthy Indoor Environment Protocols. Would we like to be able to mitigate every home? Sure, and if there was a program that provided additional funds when homes were identified as high I am sure that weatherization programs would be fine being a vehicle. But internally the focus is to not worsen health in the process of saving energy. I think that is reasonable.
