Types of Radon Test
Passive Devices
Passive radon testing devices do not need power to function. These include charcoal canisters, alpha-track detectors, charcoal liquid scintillation devices, and electret ion chamber detectors which are available in hardware, drug, and other stores; they can also be ordered by mail or phone. These devices are exposed to the air in the home for a specified period of time and then sent to a laboratory for analysis. Both short-term and long-term passive devices are generally inexpensive. Some of these devices may have features that offer more resistance to test interference or disturbance than other passive devices. Qualified radon testers may use any of these devices to measure the home's radon level.
Active Devices
Active radon testing devices require power to function. These include continuous radon monitors and continuous working level monitors. They continuously measure and record the amount of radon or its decay products in the air. Many of these devices provide a report of this information which can reveal any unusual or abnormal swings in the radon level during the test period. A qualified tester can explain this report to you. In addition, some of these devices are specifically designed to deter and detect test interference. Some technically advanced active devices offer anti-interference features. Although these tests may cost more, they may ensure a more reliable result.
General Information for All Devices
MuscleRide LLC. Radon Mitigation Systems can explain the differences between devices and recommend the ones which are most appropriate for your needs and expected testing conditions. Please contact us for more information.
MuscleRide uses a radon measurement devices from a qualified laboratory as well as continuous monitoring equipment that is nationally certified and calibrated anually to make sure your test results are as accurate as possible.
There Are Two General Ways To Test Your Home for Radon:
Because radon levels vary from day to day and season to season, a short-term test is less likely than a long-term test to tell you your year-round average radon level. However, if you need results quickly, a short-term test may be used to decide whether to fix the home.
Short-Term Testing
Whether you test for radon yourself or hire a state-certified tester or a privately
certified tester, all radon tests should be taken for a minimum of 48 hours.
A longer period of testing is required for some devices.
The quickest way to test is with short-term tests. Short-term tests remain in
your home from two days to 90 days, depending on the device. There are two groups
of devices which are more commonly used for short-term testing. The passive
device group includes alpha track detectors, charcoal canisters, charcoal liquid
scintillation detectors, and electret ion chambers. The active device group
consists of different types of continuous monitors.
Long-Term Testing
Long-term tests remain in your home for more than 90 days. Alpha track, and electret ion chamber detectors are commonly used for this type of testing. A long-term test will give you a reading that is more likely to tell you your home's year-round average radon level than a short-term test. If time permits (more than 90 days) long-term tests can be used to confirm initial short-term results. When long-term test results are 4 pCi/L or higher, EPA recommends fixing the home.
