Did You Know ...
Each year about 21,000 people die from
radori-induced lung cancer.
Nearly one in 15 homes in the U.S. is
estimated to have elevated levels of
radon. Elevated levels of radon have
been found in homes in every state. No
area of the country is free from risk.

RADON MANAGEMENT IN SCHOOLS: WHAT
YOU NEED TO KNOW TO KEEP STUDENTS AND
STAFF SAFE
What is radon, and why is it dangerous?
Radon—a colorless, odorless, radioactive gas—is one of the
most hazardous indoor pollutants. Radon is the leading cause
of lung cancer among non-smokers. In the U.S., an estimated
21,000 people die from radon-induced lung cancer annually.
Thousands of classrooms nationwide have elevated radon
levels, needlessly exposing thousands of students and staff to
this serious health risk. Testing all frequently occupied rooms
that have contact with the ground, we can identify and fix
schoolrooms with elevated radon levels.
How does radon get into the school?
Radon gas is present in the soil and enters buildings from
underground, through cracks and openings in the foundation.
Air pressure inside a building is sometimes lower than pressure
in the soil under the foundation. Because of this difference in pressure, a building acts like a vacuum, drawing
radon inside from the soil. Typical entry points include joints where the floor meets the wall, expansion joints in
the floor, openings in the floor for pipes and wires, and hollow masonry walls that penetrate the floor.
What can I do to protect my students and staff from radon?
Follow EPA's guidance on radon testing, results interpretation and mitigation in schools. Test your school for
radon. It's easy and inexpensive. Fix your school if you have a radon level of 4 pCi/L or more, http://www.epa.
gov/iaq/schools/tfs/guideg.html
HOW TO INCLUDE RADON IN YOUR IAQ
MANAGEMENT PROGRAM
The IAQ Tools for Schools Key Drivers are useful for learning how to
incorporate radon in your current IAQ management program. Some tips
include: http://www.epa.gov/iaq/schools/pdfs/kit/managing_radon.pdf.
• Organize: Use the IAQ Tools for Schools Action Kit to tie your goals for radon
testing to your overarching IAQ, health and environmental program goals.
Coordinate this effort with existing IAQ management program activities.
Frequently Asked Questions
I've tested for radon and the results
are over 4 pCi/L, what do I do next?
Start with your state radon contact.
You need to determine what best course
of action to take for your mitigation. Some
states "regulate" or "qualify" providers
of radon measurement and mitigation
services by requiring registration,
certification, or licensing; some issue
identification cards. Your state can
provide you with more information. To
date, the following states have some form
of radon requirements for radon service
providers (CA, DE, FL, IL, IN, IA, KY, ME,
NE, NJ, OH, PA, Rl, VA and WV). Visit
http://www.epa.gov/radon/
whereyoulive.html to find radon
professional resources in your state.

•	Communicate: Include radon awareness as part of your overall IAQ management training and education
efforts. Encourage parents and staff to test their homes, as the home can be a significant source of radon
exposure.
•	Assess: Perform radon assessment in conjunction with your regular IAQ walkthroughs.
•	Act: Test according to your IAQ management plan. EPA suggests initial short-term testing in all frequently-
occupied, ground contact rooms.
•	Plan: Working with your IAQ team, identify your action steps and set a schedule for your awareness raising,
testing and mitigation plan.
•	Evaluate: Determine additional testing needs and follow-up. Retest according to plan to ensure radon
mitigation systems are functioning properly.
RADON MEASUREMENT AND MITIGATION STANDARDS OF PRACTICE FOR SCHOOLS
By Jani Palmer, U.S. EPA
in the last two years, industry, government and states have been working
hard to produce the first consensus-based industry standards of practice
to address radon measurement and mitigation in schools. We are excited
to share that these standards will be available soon. The two standards
being developed: Radon Measurement in Schools and Large Buildings and
Radon Mitigation in Schools and Large Buildings.
Background
A standard is an agreed way of doing something. More specifically, it is a
published specification that establishes a common language, and contains
a technical specification or other precise criteria and is designed to be used
consistently, as a rule, a guideline, or a definition. Standards are written
by professionals and experts, drawn from the latest scientific data and
developed through a consensus process.
Whether we are hiring a plumber to fix our sink or a mechanic to change
the oil in our car, we expect them to follow a certain set of best practices. When the standard is not met, quality
often suffers. School facility professionals are aware of and commonly follow standards such as ASHRAE
(American Society of Heating, Refrigerating and Air Conditioning Engineers) Standard 62.1-2010, Ventilation
for Acceptable Indoor Air Quality, and many of the standard test methods put forth by the American Society of
Testing and Materials (ASTM).
Standards are designed for voluntary use and do not impose any regulations. However, laws and regulations
may refer to certain Standards making compliance with them compulsory.
The Process
State and federal agencies, industry and the public have identified the critical need to establish standards of
practice and codes for a range of technical components related to radon measurement, mitigation, and new
construction. Current radon standards include American National Standards Institute (ANSI) N42.50, ASTM
2121, E1465.
The American Association of Radon Scientists and Technologists (AARST) Consortium on National Radon
Standards produces many of today's radon standards according to the ANSI accredited process. In any given

week, groups of dedicated radon professionals meet to edit, vet and prepare draft radon standards for public
review and comment for promulgation as national standards of practice. Typically, standards can take as
many as two to five years from start to finish; however, the committees for the two schools standards under
development have remained committed to addressing the critical need for radon standards in schools and
are on track to complete these standards in less than two years. The committees expect to have a completed
document for public review within the next few months. Visit AARST http://www.aarst.org/consortium_radon_
standard.shtml to learn more about the radon standards for measurement and mitigation in schools and how
you can participate in setting or using these new radon standards.
Current Guidance Offered by EPA
We know that school districts pay special attention to ensuring that the professionals they hire are committed
to quality and the safety of students and staff. When it comes to IAQ, schools are faced with the challenge of
saving money and protecting health. Standards of practice can help meet this challenge by providing the basis
for quality work.
A practical first step for schools to take to protect occupants from radon is to refer to the IAQ Tools for Schools
Framework in EPA's Managing Radon in Schools document found here. This document is a good primer to get
you ready for addressing radon in your school or school district. You will see that radon testing and mitigation
can be a straightforward and organized process. Now that you are primed and ready to take action on radon,
you may want to hire a professional to test your school. Logically, you may wonder if there is a standard of
practice to which your professional should adhere.
Currently, radon and school building professionals rely upon documents produced by EPA, such as Radon
Measurement in Schools, published in 1993 and Reducing Radon in Schools: A Team Approach, published
in 1994.
Soon, school facility managers and radon professionals will have two consensus-based standards to help them
increase the reliability and the effectiveness of radon measurement in schools and radon mitigation in schools.
