Electret Ion Chambers are used for short-term radon tests (2-10 days). Short-term radon tests can be useful to get a preliminary idea of radon levels present in a home, or to provide short-term confirmation of the efficacy of a new radon mitigation system. Health Canada recommends following up the results of any short-term radon test with a long-term measurement to make informed decisions about mitigation. Only a long-term test should be used to determine the average level of radon gas exposure within a residence.
When conducting a short-term radon test, it is necessary to establish closed-house conditions to allow the radon levels to stabilize. When a radon measurement is less than 4 days in duration, closed-house conditions are to be established for the 12 hours immediately prior to starting the test and maintained for the duration of the test. If a radon test is 4 days or more in length, closed-house conditions are to be set up at the time of the start of the test and should be maintained for the duration of the test. If closed-house conditions are not established prior to the start of a short-term radon test, the results are considered invalid.
Closed-house conditions include:
Included in the purchase of a kit:
If the results of a short-term test exceed 600Bq/m³, the report will present the average radon concentration as >600Bq/m³ due to the measurement constraints of a single E-Perm®. If a more exact radon concentration measurement is desired, then additional testing may be required.
