- Testing Procedure
- 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.
