Authorizes the Department of Health to establish environmental radiation standards for buildings and to conduct programs designed to reduce human exposure to harmful environmental radiation. Requires persons who perform radon measurement and mitigation to be certified by the department and to report radon test results to the department. Requires the department to administer a public information program. Requires radon testing of all public and private schools, 24-hour care facilities owned or regulated by the state, and state-licensed day care centers located in designated counties. Requires that a specified radon warning statement be provided prior to the sale or lease of residential real estate. Regulations adopted under the law establish certification requirements (Fla. Admin. Code r. 64E-5.1201--1208). Regulations also establish that radiation exposure to the public from naturally occurring radioactive materials shall be maintained as low as reasonably achievable and that the annual average radon decay product concentration in a building shall not exceed 0.02 WL (4.0 pCi/L) (Fla. Admin. Code. R. 64E-5.1001).

Requires the Department of Health to conduct environmental health surveillance, including an IAQ testing and monitoring program to assess health risks from exposure to chemical, physical, and biological agents in the indoor environment.

Provides funds to the Department of Business and Professional Regulation for activities incidental to the development and implementation of building codes for radon-resistant buildings. Regulations implementing the law (Fla. Admin. Code r. 61-38.002--.003) adopt a voluntary, model Standard for Passive Radon-Resistant New Residential Building Construction and Standard for Radon-Resistant New Commercial Building Construction. Requires that local jurisdictions that choose to adopt requirements for radon-resistant new construction use the model standard adopted by the state.

Authorizes the board of a housing cooperative to take certain actions in response to damage caused by an event for which a state of emergency is declared. Authorized actions to mitigate further damage include contracting to remove debris and to prevent or mitigate the spread of fungus (including mold or mildew) by removing and disposing of wet drywall, insulation, carpet, cabinetry, or other fixtures on or within the cooperative property. (Separate law, Fla. Stat. § 720.316, authorizes neighborhood associations to take similar actions on or within the association property.)
