The Radon Remediation Act mandates testing for dangerous levels of radon in school buildings, residential buildings, residential homes, and commercial buildings in Pennsylvania. The act defines key terms such as "dangerous level of radon," which is set at levels above four picocuries per liter, and outlines the responsibilities of various stakeholders, including school directors, landlords, residential home sellers, and commercial building owners. Each entity is required to conduct radon tests by specific deadlines, provide notifications regarding test results, and implement remediation measures if dangerous levels are detected. Additionally, ongoing testing every five years is required to ensure continued safety.

The act also establishes penalties for non-compliance and empowers the Department of Environmental Protection to create rules and regulations for enforcement. Key provisions include the requirement for school directors to notify parents about radon test results, landlords to inform prospective tenants, and sellers to disclose radon levels to buyers. The act aims to protect public health by ensuring that buildings are tested and remediated for radon exposure, thereby reducing the risk of health issues associated with high radon levels.
