As a service for helping our clients, DrHomeAir is providing the following guideline for accurate testing, adapted from Environmental Protection Agency (EPA) information.

DO:

	Follow the instructions that come with your Radon test kit.
	For short-term tests, close your windows and outside doors at least 12 hours before you begin your test. Keep them closed as much as possible during the test. Do not operate fans or other devices that bring air in from outside.
	For long-term tests, use the rooms, windows and doors as you normally would, without disturbing the test kit.
	Operate the home's heating and cooling systems normally during the test. For short-term tests, operate only air-conditioning units that recirculate interior air.
	Place your test kit in a frequently used room like a bedroom or den on the lowest living area in your home.
	Place the testing device at least 20 inches from the floor where it will not be disturbed.
	Leave the test kit in place for the full length of time that the package instructs.
	Completely fill in the information form on the back of your text kit.
	Send your test kit to the lab specified on the package immediately after the test period is complete.

DON'T:

	Conduct your test during periods of severe storms or high winds.
	Place your test kit in a bathroom or kitchen.
	Disturb the test kit once it has been placed.
	Place near heat, humidity or exterior walls.

If your home has been tested and found to contain high levels of radon (greater than 4.0 pCi/L), it is highly recommended that you seek help from a professional radon reduction contractor. A radon reduction contractor is a contractor who is trained to fix radon problems in homes, schools, and office buildings. When selecting a radon reduction contractor, keep in mind that choosing someone to fix your radon problem is much like choosing a contractor for other home repairs; you may want to get references and more than one estimate. Call your state radon office for a list of the names of state-certified radon reduction contractors in your area. Your state radon office may also have information about certification requirements for these contractors. These radon reduction contractors will be able to:

	Review testing guidelines and measurement results and determine if additional measurements are needed.
	Evaluate the radon problem and provide you with a detailed, written proposal on how radon levels will be lowered.
	Design a radon reduction system.
	Install the system according to EPA Standards and State or local codes.
	Make sure the finished system effectively reduces radon levels to acceptable levels.

	An EPA listed activated charcoal radon test kit, shipped directly to your door.
	Postage-paid, pre addressed envelope for mailing your test kit in for laboratory analysis.
	Fully national and state certified laboratory analysis.
	A complete written report describing your home's current radon levels, with suggestions for any future steps required.
