- Easy testing - simply remove testing device from sealed pouch and expose to the air for 3 months to 1 year. Place completed test device in shipping pouch and mail to the lab.
- AccuStar Labs remains the only laboratory in the United States to use electrochemical etching to process its alpha track foils which are subsequently counted with computer-aided image analysis equipment. This kind of system was found superior to chemically etched alpha track radon detectors.
- Complete testing instructions and information reporting sheet.
- Test results available 24 hrs. a day online and via automated phone the next business day afternoon after the lab receives the sample.
- Test results also mailed out the next business day after receiving the sample.
- Price includes laboratory analysis.
- First Class U.S. postage prepaid return packaging.No return shipping costs to the lab.
- AccuStar is a certified National Radon Proficiency Program laboratory registered with the National Environmental Health Association and is registered with every US state that requires registration for Radon testing.
- Note: Not available in New Jersey.
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.
Cut or tear the pouch open and remove the Alpha track detector. Do not remove the cover of the test device. Expose to room air for a period of 3 months to 1 year. Three months should be the minimum for this type of test. When exposure time is complete, place the testing device into the U.S. postage prepaid mailing envelope along with the information sheet and mail it.
Information Form Recording
- Name and address.
- Serial number of the test device.
- Start and end dates and times of the test.
- Record the location of where the canister was exposed (basement, living room, etc.).
Analyzing the Results
The Alpha Track radon monitor is a diffusion-based track detector. The current improved design filters out dust and radon progeny through a structural filter that is an integral part of the housing, resulting in increased sturdiness. The housing is injection molded from electrically conducting plastic in order to minimize electrical charge effects from the positively charged radon progeny generated inside the detector. The hemispherical base is designed to maximize sensitivity and create a more uniform track distribution for better counting statistics.
The track detector foil inside the housing is from dosimetry-grade CR-39 cast specifically for AccuStar Labs. The sheets of CR-39 are laser cut and engraved with a unique batch number. Each batch is calibrated and receives its own calibration factor. All sheets are also checked for background tracks.
AccuStar Labs remains the only laboratory in the United States to use electrochemical etching to process its alpha track foils which are subsequently counted with computer-aided image analysis equipment. This kind of system was found superior to chemically etched alpha track radon detectors in an article comparing radon detection methods by John Matuszek of the New York State Department of Health (J.M. Matuszek, et al., "Standardization of Radon Measurements", Environmental International, December 1988).
All detector foils are counted using a computer-aided image analysis system. The automated equipment is quite reproducible; rereads of the same group of foils have a mean within 2% of the original mean and coefficient of variation of 5%. The detector has an uncertainty of only 12% with a three-month 4 pCi/l exposure. The lower limit of detection is 0.8 pCi/1-month.
