EPA Factsheet: What is Indoor Air Quality?

July 2025: This Environment Protection Agency (EPA) factsheet (also available in Spanish) discusses what is indoor air quality, common sources and factors that can impact indoor air quality, and best practices for improving and maintaining good indoor air quality.

EPA Indoor Air Quality Tools for Schools Action Kit (Reference Guides, Checklists, Fact Sheets)

The EPA’s IAQ Tools for Schools Action Kit provides practical, low- or no-cost strategies to help schools and child care programs improve indoor air quality using simple, in-house approaches. This resource includes best practices, industry guidelines, sample policies, and a model IAQ management plan to support implementation. The page also offers a variety of supporting materials such as reference guides, checklists, and fact sheets, making it easy to find actionable tools for day-to-day use.

EPA: Coordinator's Guide for Indoor Air Quality

The EPA’s Coordinator’s Guide for Indoor Air Quality is a comprehensive resource designed to help schools and child care programs establish and manage an effective IAQ program. It walks users through key steps such as developing an IAQ plan, implementing the EPA’s Tools for Schools framework, and using model policies and forms to support ongoing efforts. With practical guidance, templates, and policy examples included in the appendices, this guide serves as a step-by-step resource for building and sustaining healthy indoor environments.

Health Effects of Radon

Radon is a colorless, odorless, and tasteless radioactive gas that forms naturally in soil and rocks and can migrate into homes and other buildings through basements, slabs, and foundations. Once inside a building, radon can accumulate to high concentrations, resulting in radiation exposure to occupants. The harmful health effects of radon occur when radioactive particles are inhaled and settle in the lungs, where they can damage lung tissue and increase the risk of lung cancer over time.

Children are especially vulnerable to radon exposure. Because their lungs are still developing and they breathe more rapidly than adults, children can inhale higher doses of radiation relative to their body size. In addition, children in ECE programs may spend many hours each day in the same classroom or indoor space, increasing the duration of exposure if radon levels are elevated. Long-term exposure during these critical periods of growth can increase a child’s lifetime risk of developing lung cancer.

Pennsylvania Consumer's Guide to Radon Reduction

Revised in April 2024 this Radon Reduction guide (PDF) from the PA Department of Environmental Protection Bureau of Radiation Protection explains radon, remedies, and much more from their PA Radon Information Center.

Recommended Action Checklists for Improving Indoor Air Quality in Schools

The EPA’s Recommended Action Checklists for Improving Indoor Air Quality in Schools provide practical, role-specific strategies to help create and maintain healthy indoor environments. The page offers a high-level summary of key actions, organized by responsibility (e.g., administrators, design teams, construction supervisors, and facility managers), with links to more detailed guidance for each item. Users can quickly identify relevant responsibilities and access deeper explanations, making it a useful starting point for improving air quality practices in school and child care settings.
