Filter for on-line air monitor unaffected by radon progeny and method of using same
Patent
·
OSTI ID:20013231
This invention relates to an apparatus for testing air having contaminants and radon progeny. The method includes providing a testing apparatus that has a sampling box with an inlet for receiving the air and an outlet for discharging the air. The box has a sintered stainless steel filter. Air is drawn from a source into the sampling box using a vacuum pump, passing the air through the filter. The contaminants trapped by the filter are monitored. The apparatus provides an alarm when a selected level of contaminants is reached. The filter traps the contaminants, yet allows at least a portion of the radon progeny to pass through.
