Before You Begin Your Short-Term Radon Test

1. Go to accustarlabs.com/ls to register device and fill out online data form (or scan QR code on your printed instruction) 
2. Ensure that testing guidelines are followed
3. DO NOT open test device until you are ready to start your test
4. Record your device number(s) and Keep for your records

Start the test before the expiration date on the device. The test duration is 2-4 days (48-96 hours). Unusual weather conditions affect test results. Do not perform the test during sustained high winds, heavy rain or extreme indoor conditions of heat, cold or humidity. Short term tests should not be placed in areas of high humidity. If humidity is unavoidable, tests placed in humid areas should not be exposed for more than 48 hours (2 days). A longer test duration may invalidate results.

Failure to follow the testing instructions or protocols may result in an invalid test. These instructions cannot anticipate or address every condition that arises when performing a radon test. Some states have regulations regarding radon testing. If you have questions about your state’s requirements please contact your State Radon Office.

Closed Building Conditions

• Close all exterior doors and windows in the house and keep them closed except for normal entry and exit, as if it is winter
• Air conditioners should be set to auto or recirculate
• These conditions must be maintained 12 hours before and during the entire test
• The temperature of the area being tested should be between 50-85°F
