Alpha Track Radon Detector Instructions
A. Timing Guidelines
This alpha track radon detector can be used for test periods from 8 days to one year. Radon levels, like temperature, vary day-to-day and season-to-season, and in response to weather conditions and ventilation patterns. The longer you test, the more closely your result will represent the true average radon concentration.
B. Placement Guidelines
Radon concentrations can vary with location in a building. Radon usually enters a building from the soil underneath the basement or foundation, and radon concentrations are usually highest in the lowest level of the building.
The U.S. EPA recommends that “the test kit should be placed in the lowest lived-in level of the home (for example, the basement if it is frequently used, otherwise the first floor).” It should be put in a room that is used regularly, a living room, playroom, den, or bedroom, but not a kitchen, bathroom, laundry room, furnace room, closet, stairway, hallway, or crawl space.
Do not test in an enclosed area of high humidity or high air velocity. Avoid placing the detector near drafts, drains, sumps, or sources of heat, such as furnaces, fireplaces, water heaters, and clothes dryers.
Place your detector in the breathing zone, 2–6 feet above the floor, and at least one foot from exterior walls and three feet from windows and exterior doors. Place the detector at least four inches away from other objects and in a location where it will not be disturbed.
C. Starting Your Test
- Open the protective pouch and remove the radon detector. Discard the pouch. If your detector rattles or if the top or bottom label is torn, do not use the detector. Call the RSSI radon laboratory at 800-762-7774 for a replacement.
- Write the start date on the top label.
- If you plan to hang the detector, firmly slide the hook into the groove on the bottom of the detector.
- Save the hook, data form and these instructions.
- Do not disturb the detector during the test period.
D. Ending Your Test
- Write the end date on the top label.
- Fill out the data form.
- Do not attempt to reseal the detector or place anything over the filter opening.
E. Return Detector to RSSI
- If the test is 8-14 days, your detector must be returned to RSSI’s lab by overnight service to minimize exposure during transit.
- Place the data form, detector, and hook in a box.
- If the test was 15 days or longer you may ship ground or via the US Postal Service.
