Overview of EPA's State & Tribal Indoor Radon Grants Program:

A Focus on Activities Conducted During 2022

Radon is the second-leading cause of lung cancer after smoking. Effective, affordable measures to
reduce radon in homes and buildings are available and when employed, can prevent radon-induced lung
cancer and save lives. For more than 30 years, the U.S. Environmental Protection Agency (EPA) has
provided critical funding to support state, territory, and tribal efforts to reduce radon-related lung
cancer through the State & Tribal Indoor Radon Grants (SIRG) program. This collaborative partnership
between the states, territories, tribes, and EPA is critical in reducing radon risk and saving lives.

Despite notable progress, radon continues to be a serious public health concern in the United States.
Millions of homes with elevated radon levels remain, and it is estimated that approximately 20,000
Americans die annually from radon-induced lung cancer, including people who have quit smoking or
never smoked. In fact, radon-induced lung cancer ranks among the top 10 causes of all cancer deaths in
the United States among adults who have never smoked.1 This reinforces the need for expanded radon
testing for all homes and buildings, public health-focused policy adoption, and risk reduction measures
such as mitigation of elevated radon levels and radon-resistant new construction practices. State,
territory, and tribal radon programs are vital to implementing successful programs aimed at reducing
radon risk.

Reflecting on the past year:

Indoor air quality (IAQ) has increased as a public health priority for many families and communities, in
part, due to the pandemic. State and tribal radon programs, advocates, industry professionals, National
Radon Action Plan (NRAP) member organizations, and public health agencies continue to address radon
as a critical IAQ issue by building partnerships aimed at addressing emerging challenges and advancing
risk reduction. The most impactful radon risk reduction strategies and policies directly result in
expanded testing of homes and buildings, mitigation of high radon levels, and the construction of new
homes and buildings that are radon resistant.

EPA has developed this annual report to highlight successful state and tribal grantee approaches in six
key areas of focus. The report primarily covers activities conducted during the 2022 SIRG reporting cycle
(October 1, 2021 - September 30, 2022).

48 states and 13 tribes requested and received SIRG funding to support their radon programs in 2022.
Of note, since 2021, four additional tribes received funding to help establish radon programs: the Forest
County Potawatomi Community, the Saint Regis Mohawk Tribe, the Seneca Nation of Indians, and the
Shinnecock Indian Tribe.

In addition to the overall national progress supported by SIRG funding, EPA continues to look for
opportunities to assist underserved communities through state and tribal radon grants. Some state and
tribal radon programs pair SIRG funding with other healthy housing, housing finance, and/or low-income
mitigation assistance program funding to expand opportunities for residents to access testing and

mitigating resources. Several success stories demonstrate a commitment to assisting underserved
communities, including North Carolina's radon professional scholarship program, Alabama's Healthy
Homes Initiative, and Rhode Island's partnership with the Lead Safe Providence Program. These stories
highlight the important work SIRG recipients are doing to support vulnerable and often underserved
communities. This summary report and the variety of program activities and approaches shared by
states and tribes highlight the importance of partnership, community-tailored programs, and lasting
approaches to radon risk reduction.

Key Take-Aways and Significant Progress:

•	47 of the 48 states (including Washington, DC) and eight of the 13 tribes that received FY22 SIRG
funding submitted information on planned and conducted radon activities.

•	Recently, EPA has focused on expanding the number of tribes receiving SIRG funds. In 2022, 13
tribes received funding which is nearly double the number of tribes funded just a few years ago.

2 To ensure broad representation, this map also shows non-funded states and territories, as well as currently and recently funded tribes (within the
last 10 years). Several recently funded tribal grantees appear on the map even if they didn't receive funding during the most recent reporting cycle
because they may still have active radon programs and/or carry-over funds from a previous year. Depending on regional allocations tribal funding
may rotate among tribes from year to year, and sometimes risk reduction work continues even in the absence of funding or through carry-over
funds.

•	Grantees continue to make progress adopting radon-resistant new construction requirements at the
state and local level. Montana and Washington, DC adopted the International Residential Code
Appendix F: Radon Control Methods (IRC Appendix F) as a voluntary part of the construction code.
In Montana, local jurisdictions can adopt construction requirements outlined in IRC Appendix F, and
several counties in Virginia and West Virginia recently adopted IRC Appendix F requirements.

•	Iowa and Wisconsin recently passed comprehensive radon testing and mitigation policies in schools
and childcare facilities, respectively.

Spotlight; Successful Approaches for Reducing Radon Risk

This section showcases examples of state and tribal projects and activities under key risk reduction

strategies funded in part by EPA's SIRG program.

Adoption of radon-reduction strategies including state policies/regulations or building codes:

•	The Montana Building and Commercial Measurements Bureau adopted and incorporated by
reference the IRC Appendix F as a voluntary part of the state construction code. Within the state,
local jurisdictions can elect to adopt the radon construction requirements.

•	Florida has regulations in place regarding mandatory testing in early education centers, schools, and
some 24-hour care facilities (including nursing homes, assisted living facilities and hospitals). During
this reporting cycle, the Florida Radon Program sent reminder emails to these facilities about testing
requirements, which resulted in a significant increase in testing for facilities, with nearly 390
facilities reporting test results. Through these outreach efforts, Florida has seen an increase in
buildings tested and has encouraged more people to become state-certified radon measurement
professionals. The state certified 50 new measurement professionals last year.

•	In Colorado, a new radon measurement and mitigation licensure law took effect in July 2022. The
law indicates that, "an individual is prohibited from practicing as a radon measurement professional
or radon mitigation professional unless the individual is licensed by the director of the division of
professions and occupations in the department of regulatory agencies."

•	In June 2022, the New Jersey Department of Environmental Protection adopted new radon
certification regulations outlining the requirements for any person or business that wishes to
perform radon testing or mitigation service in the state. These replace existing regulations and
represent a culmination of several years of work aimed at ensuring stronger public health
protections for state residents. Through the new regulations, New Jersey residents will have
increased confidence in the radon services provided by certified individuals and businesses.

•	In Indiana, licensed primary testers, laboratories, and mitigators are required to report all radon
activity to the Indiana Department of Health (IDOH). As a way of streamlining reporting and
improving IDOH's ability to characterize measurement and mitigation results, the state developed a
web-based reporting tool designed to allow licensees to report more frequently, eliminate duplicate
test data, and reduce the number of incomplete data submissions.

•	In Virginia, Louisa County adopted IRC Appendix F into the local building code, requiring radon
resistant new construction.

•	In July 2022, the Michigan Radon Program collaborated with a radon-resistant new construction
(RRNC) stakeholder group to submit proposed updates to the state's Residental Building Code. The
proposed changes would expand RRNC requirements to all 83 Michigan Counties. (Nine counties
currently have RRNC requirements in place.) The rulemaking process on Michigan's Residental
Building Code is expected to take approximately 12 months.

•	In West Virginia, nine new municipalities or counties adopted IRC Appendix F into building codes.
Testing and remediation of schools and childcare facilities:

•	In Iowa, the Gail Orcutt School Radon Safety Bill (HF 2412) was signed into law and took effect in
July 2022. It requires all public schools to test for radon by July 2027, and every 5 years thereafter.
Schools must follow recognized national standards for radon testing. School districts are also
required to mitigate buildings if testing shows elevated radon levels, and all new school construction
is required to incorporate radon resistant construction techniques. The comprehensive law also
requires that testing is completed by an Iowa Certified Measurement Specialist or by district staff
that have completed an approved training course.

•	Beginning in March 2023, the Wisconsin Department of Children and Families (DCF) will require
radon testing in all licensed childcare centers, and remediation when necessary. This is the first
piece of legislation passed in Wisconsin that is directly focused on radon testing and mitigation. The
Wisconsin Radon Program (operated by the Wisconsin Department of Health Services) is working
closely with the state's DCF and Kansas State University to develop trainings for licensing specialists,
childcare providers, and measurement and mitigation professionals.

•	The Maine Department of Education requires schools to be built using radon resistant new
construction. The state is continuing a multi-year project of testing all schools by 2025. During this
reporting cycle, the state tested more than 15 additional schools.

•	The Oregon Radon Awareness Program (ORAP) partnered with the Choose Safe Places Program (a
non-regulatory program that helps childcare providers make safe decisions regarding childcare
locations) to create radon educational materials for childcare providers. The materials include a
one-pager about radon and children's health impacts, simplified short-term test kit instructions, and
ORAP's "Have You Tested Your Home for Radon" brochure translated in six additional languages.
Childcare facilities will also be able to request free radon test kits if they operate out of homes
located in high-radon risk or undetermined-radon risk zip codes or express an interest in testing.

•	The Navajo Nation Environmental Protection Agency is partnering with the Health Education and
Human Services Committee to develop a radon testing policy for schools on the Navajo Nation. If
the policy is approved, schools may be tested every two to three years in the future.

Addressing radon in homes and residential real estate transactions:

•	The Bad River Band of Lake Superior Chippewa Indians Radon Program partnered with the Bad
River Band Housing Authority to test 35 homes during this reporting cycle.

•	In Idaho, Blaine County requires radon mitigation systems to be installed on all new residential
structures. During this reporting cycle, the county received approximately 90 building permits for
new residential construction projects.

•	Washington Radon Program developed a free radon test kit program for homeowners and renters
to promote and increase testing in homes. State residents (including homeowners, renters, and
landlords) may complete a form and provide address information to request a free test kit. To make
this test kit program more accessible, the request form was recently translated into several non-
English languages (Russian, Spanish and Vietnamese).

•	The Pueblo of Pojoaque Environment Department provided technical assistance and construction-
phase radon system guidance to the Pueblo of Pojoaque Housing Corporation which is currently
working on a 25-home single-family tribal housing construction project.

•	The St. Croix Chippewa Indians of Wisconsin are partnering with their Tribal Housing authority to
encourage and educate homeowners about testing for radon while homes are undergoing repairs or
as a normal part of home maintenance.

Inclusion of radon in cancer control plans:

•	The Connecticut Cancer Control Plan 2021 - 2026 includes a radon objective aimed at increasing the
percentage of households that test for radon from 48.2% to 53%. The plan includes strategies based
on promoting public awareness regarding radon exposure and encouraging radon testing and
reduction in homes, schools, and workplaces.

•	The District of Columbia (DC) submitted a document called "Radon in the District of Columbia" for
inclusion in the Department of Health's upcoming 2022-2027 DC Cancer Control Plan. Previous
versions of the District of Columbia's plan did not include radon awareness or strategies. The
inclusion of radon strategies in the upcoming cancer control plan would represent an increased
focus on radon risk reduction and preventing radon-induced lung cancer for District residents.

Education and outreach to the medical community:

•	The Massachusetts Department of Public Health's (MDPH) Comprehensive Cancer Control Program,
Environmental Public Health Tracking Program and IAQ Program collaborated with the
Massachusetts Medical Society to develop and record a Continuing Medical Education (CME) course
entitled, "Radon Exposure and Health Risks." Physicians can obtain CME credits for attending the
course. During this reporting cycle, the course received more than 800 views and 200 course
completions.

•	The Spokane Tribe is partnering with the Washington State Department of Health to develop a
process for sharing radon test laboratory data with the CDC Environmental Health Tracking
Network. The Spokane Tribal Air Quality Program is also working with the Spokane Indian Housing
Authority (SIHA) to distribute radon tests to homes and develop a streamlined process for collecting
laboratory test results from tribal homes.

•	In addition to developing and distributing radon risk information with tribal members and tribal
housing and government construction representatives, the Nez Perce Tribe initiated a partnership
with the Northwest Tribal Epidemiology Center as part of an effort to collect lung cancer data for
counties that intersect with the reservation. Tribal Epidemiology Centers work in partnership with
the local or area tribes to improve the health and well-being of tribal community members by
offering culturally competent approaches that work toward eliminating health disparities.

•	The Utah Radon Program works closely with the Huntsman Cancer Institute to explain the risks of
radon exposure and to distribute test kits to residents, especially to low-income and lung cancer
patients that are current smokers.

•	The New Hampshire Radon Program developed a partnership with the New Hampshire Tracking
Program to collected radon testing and mitigation data. In Spring 2023, the state plans to submit
data collected to the CDC Environmental Public Health Tracking Network for the first time.

Continuing education, outreach, and technical support:

•	The Minnesota Department of Health (MDH) created several online continuing education training
courses for stakeholders. This web-based virtual training has many benefits including increased
accessibility for individuals in rural areas, an advantage in a large state like Minnesota. Recently,
MDH developed a Learning Center website to host these courses and includes on-demand recorded
courses and associated tests. Adding the radon licensee course to the MDH Learning Center website
has greatly improved the state's ability to track and record learning for individuals seeking radon
licenses, and individuals may receive a certificate and submit licensing continuing education
requirements directly through the website.

•	The North Carolina Radon Program has been expanding its work with minority and underserved
communities through strategic partnerships across the state, including with the North Carolina
Department of Health and Human Services Historically Marginalized Populations Workgroup, Latin
19, Wake Forest University Health Disparities Program, and the Duke Cancer Institute Health
Disparities program. Through these partnerships, the state is developing new educational and
research efforts to reach renters and people of color, as well as offering scholarships for minority
contractors to become certified radon professionals.

•	The Tennessee Radon Program received over 6,000 radon test kit requests following a news story
about the state test kit program aired on nightly news in Eastern Tennessee. This provided the
program with an opportunity to raise radon awareness to a wide audience throughout Eastern
Tennessee, an area that typically has higher radon levels than other parts of the state.

•	The Kansas Department of Health and Environment (KDHE) developed a map designed to help state
residents locate radon professionals in their area. KDHE surveyed professionals to better understand
where they are located and where they are willing to travel. This geographical information was
incorporated into a new map providing state residents a clearer picture of service coverage and an
easier way to locate radon professionals.

•	The Nevada Radon Education Program partnered with Emmy Award-winning Three Sticks
Productions and the Nevada Broadcasting Association to develop several videos educating Nevadans
about the dangers of radon exposure and the importance of testing their homes. The videos are
available on the state program's radon website and the University of Nevada Reno Extension's
YouTube channel.

•	The Alabama Radon Program partnered with the state Department of Public Health and the
University of Alabama to advance work on the Alabama Healthy Homes Initiative. The state's radon
program provided radon information and test kits to residents while the project leveraged funding
from a Department of Housing and Urban Development (HUD) Healthy Homes Production Grants
designed to remove environmental and safety hazards from some of Alabama's vulnerable and
underserved communities.

•	The Central New York Coalition for Healthy Indoor Air, Inc. collaborated with the New York Radon
Program to develop two Model Radon Demonstration Houses. These models show how radon can
enter and exit a home through various natural and mechanical pathways. In addition, the Central
New York Coalition for Healthy Indoor Air has partnered with local housing agencies to test homes
during weatherization improvements and leverage grant funds to assist with mitigations, when
necessary.

•	The Rhode Island Radon Program partnered with the HUD-funded Lead Safe Providence Program to
provide radon testing and mitigation services in 40 income-qualified homes as well as outreach and
education to tenants. In addition, the program provided technical assistance to the Pawtucket
Housing Authority, which tested three public housing facilities (totaling more than 350 units) under
a HUD Housing-related Hazards Capital Fund Program.

•	The Pennsylvania Department of Environmental Protection published an article titled: "Residential
Homes with Extremely High Indoor Radon Concentrations in Southern Lehigh County, Pennsylvania"
in the Health Physics Journal. The paper focuses on pre- and post-mitigation testing in single family
homes in a geologic unit known as the Epler Formation, in the southern Lehigh County area.
