Alpha Track FAQs
You may want to do more than one test if:
- Your home’s foundation is over 2,000 square feet
- You have a basement and a crawl space – test in the basement and in the room above the crawl space
- Your home is a 4 level split – test each floor that is in contact with the ground
The US EPA recommends you test the lowest level of the house that is regularly used for 8-10 hours per week. If you are making a follow-up measurement, the US EPA recommends placing a device on each level that is used for living space in your home. Do not test in the kitchen, laundry area, bathroom, crawl space, furnace room or closet. Hang or place each device at least three feet away from exterior doors or windows and at least two feet off the floor. If you want to do a duplicate test, place the two devices side by side, 4″ apart.
When you are ready to start the test, cut or tear open the sealed plastic bag that contains the black device. As soon as you open this plastic bag the device is “on” and the test has begun. Do not remove the VOID sticker or open the black plastic housing or the results will be invalid.
The Alpha Track device may be placed face up or face down. It does not matter. You can also choose to hang the device from a string using the small cut out in the black housing of the detector. Once you place the device, it should remain undisturbed for 91 to 365 days.
Leave each device in place and undisturbed for at least 91 to 365 days.
You must expose an Alpha Track for at least one month. You cannot get a result for your Alpha Track device if you have left it out for less than 30 days. The maximum exposure time for the Alpha Track is 2 years. If you expose it longer than 2 years you cannot get a result.
Yes. Alpha Track devices should be stored in conditioned space. Do not keep your alpha track devices in your vehicle because extreme temperatures could affect their sensitivity.
Test results can be expected within two weeks of the lab receiving your test kit.
