If your home has a basement, open and place the canister anywhere in the basement. Do not place the canister in a garage, root cellar, crawl space or sump pump pit. If your house does not have a basement, place the open canister in the lowest livable level of your home in any room except the bathroom, kitchen, laundry room or porch. If testing more than one area of your home, place the other canister in a frequently used living area.
Do not expose the canister to noticeable drafts such as near a window, fireplace or open door. Canister should be placed at least 2 feet above the floor, at least 1 foot away from exterior walls, at least 4 inches away from other objects and at least 3 feet away from windows, doors or other openings. Do not place in cupboard, closet, drawer, etc. Canister should be exposed to the air people breathe.
Remove the cap of the test device and expose to room air for a period of 48 to 96 hours (2-4 days). Do not touch or disturb the test canister during the test period. Do not expose the device to the air for longer than 4 days as over exposure will invalidate the results. When exposure time is complete, securely seal the canister with the cap. Complete the information form and place it with the sample test canister in the U.S. postage prepaid package and mail it immediately. The lab must receive the test within 8 calendar days to have a valid test.
- For 12 hours prior to the test and during the testing period, the doors and windows must remain closed to the test area.
- During the test period, turn off all fans that bring outside air into the house or vent large amounts of air from the house such as whole house fans.
- Do not operate fireplaces, wood or coal stoves unless a primary source of heating.
- Devices that re-circulate indoor air such as humidifiers or air conditioners that are set to re-circulate can be used normally.
- Avoid blowing air directly over the test device.
- Tests should not be conducted under severe weather conditions (heavy rains, high winds, extreme heat, cold or humidity, etc.).
- Mail the canister sample within one day of completing the test.
Information Form Recording
- Name and Address.
- Serial number of the test.
- Start and end dates and times of the test.
- Record the type of room where the canister was exposed (basement, living room, etc.).
- Record the level of the house where the canister was exposed (basement, 1st floor, etc.).
- Indoor conditions - temperature and humidity ranges.
Analyzing the Results
The canister is a 6 cm. high by 2.5 cm. diameter high-density polyethylene liquid scintillation vial. The 22-ml capacity vial is designed to hold a small canister near the opening above the scintillating fluid. The canister, made of high-density polyethylene, contains a patented pharmaceutical-grade charcoal-silica adsorption material.
This patented device configuration produces minimum attenuation of the scintillation signal. Perforated end caps allow air to circulate through the mixture and retain any charcoal dust. A polyethylene cap, capable of sealing tightly, prevents the loss of Radon gas from the vial.
After exposure, the vial is returned to the laboratory for analysis. Scintillation cocktail is added and the Radon allowed an elution period of several hours. The vial is then placed in a shielded chamber for counting.
Alpha particles emitted by the breakdown products of Radon create scintillations, or flashes of light, in the cocktail. A photo-multiplier tube detects these scintillation's, the signal is electronically enhanced and the effect of the alpha particles are counted. Background counts are subtracted and the net counts are entered into a formula with other relevant data yielding quantitative results stated in picoCuries per Liter (pCi/L).

NOTE: The lab must receive your sample within 8 calendar days. All test kits have return U.S. postage prepaid for first class US Mail and are to be delivered to Massachusetts. Generally, there is no problem in meeting this delivery timeframe, however if there are holiday weekends and you live on the west coast, Canada, Alaska, Hawaii, etc. or there are winter storms that may cause a delay in the US Postal Service, please consider sending the sample with US Priority Mail, which is a 2-3 day service.
