Accustar Alpha Track AT-100 Long Term Radon Gas Test Kit (91 day to 12 month test period)

LAB FEES INCLUDED - According to the EPA, a long-term test is the best way to determine your exposure to Radon during different seasons and living conditions in your home. Closed house conditions are not necessary during a long term test. EPA recommends using 2 units per 1200 square foot dwelling. Lab results are available online within 12 to 14 days of receiving them back in our lab - click here for results. OUR LABS ARE EPA CERTIFIED Click here for NJ test kits

Our long term detector is a diffusion-based track detector originally designed in 1986. 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 by American Techniplastics. 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.

Each detector is given a unique bar coded number and sealed inside a radon-tight pouch. The unique REM Nu-Clear pouch is transparent, which prevents any labeling errors from occurring.

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%. Large numbers of tracks can be counted, up to 10,000 tracks per foil, thus improving range and precision. 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.

  • Rugged structural filter for both indoor and outdoor use
  • Twin removable serial labels, human and bar code readable
  • Electrochemical etching for better track resolution
  • Clear direct read pouch reduces serial errors
  • Large foil area counted for better statistics (over 40 square mm)
  • Hemispherical housing base for better track distribution
  • Electrically conducting housing reduces charge effects and clustering
