Interventions

Federal: Toxic Substances Control Act (1988)

• EPA provide educational material

• no monitoring or abatement

• EPA recommend & encourage testing/mitigation

• State Indoor Radon Grant (SIRG)cost of mitigation: schools & non-consumer

Radon Legal Environment

Some states

• requiring disclosure in home purchase (CT) rental agreements (IL)

• Radon testing every X years (ME)

• Tax credits for radon-free buildings (NY)

Radon Legal Environment

SchoolsZone 1 landlords and follow up every 2years (1 & 3)

Pyramid Level 2

• Free radon testing kits to Zone 1 areas • tax credit for RRNC• interest free loans• Media campaigns and radon information pamphlets• radon resistant/ radon under control certifications (2 & 5)

Pyramid Level 3

• RRNC–$250-$750 • Radon mitigation $800-$2500 under home insurance/ renters insurance plans • Mandatory follow up testing (1 & 3)• HCW - door-to-door radon services

Pyramid Level 4

Professional training $125-$600 per person

Health check-up under insurance plans

Pyramid Level 5
