There are several different types of radon tests available to measure the levels of radon gas in a home or building. The most common types of radon tests are short-term tests, long-term tests, and continuous radon monitoring.
- Short-term tests: Short-term radon tests typically measure radon levels for a period of two to seven days. These tests are designed to provide a quick snapshot of radon levels in a home or building. Short-term tests are often used to determine if further testing is needed or if immediate mitigation measures are required.
Short-term tests can be conducted using a variety of testing devices, including activated charcoal, electret ion chambers, and alpha track detectors. Activated charcoal tests involve placing a small container filled with activated charcoal in a room of the home or building to absorb radon gas. The charcoal is then analyzed in a lab to determine the level of radon exposure.
- Long-term tests: Long-term radon tests measure radon levels for a period of three months to a year. These tests provide a more accurate and reliable measure of radon exposure over time. Long-term tests are often used to determine the average radon level in a home or building and to monitor changes in radon levels over time.
Long-term tests can be conducted using similar devices as short-term tests, including alpha track detectors, electret ion chambers, and continuous radon monitors.
- Continuous radon monitoring: Continuous radon monitors are electronic devices that provide real-time measurements of radon levels in a home or building. These monitors are often used for short-term or long-term testing, as they can provide a continuous measurement of radon levels over time.
Continuous radon monitors can be set up in a home or building and left to monitor radon levels over a period of time. Some devices can also provide hourly or daily readings of radon levels.
It is important to note that regardless of the type of test used, proper testing protocols must be followed to ensure accurate results. This includes placing the testing device in the correct location, avoiding interference from external factors such as humidity or temperature, and following manufacturer’s instructions for device placement and analysis. It is also important to ensure that the testing device is calibrated correctly and that the lab used for analysis is certified to perform radon testing.
