There are indeed two different types for the structure and for water. The testing for water is to capture a specific volume of water completely void of any air bubbles. The sample is then provided to a certified lab for analysis and the resulting radon level is determined.
For testing radon concentrations in air there are several capture methods. The first is standard charcoal canisters. While these are the most economical they bring with it a potential for inaccurate results. Another method is an ion capture chamber, most often recognized by a trade name such as EPERM. These will be more expensive to deploy/test with as they are not available for use by the consumer, however, they are extremely accurate and can be deployed for a longer timespan than charcoal which further improves the accuracy of the test. Another method is a continuous monitoring system. These are even more expensive to deploy than the previous two methods but are not any more accurate than the ion capture chamber type of test.
There are other methods of testing available yet the three methods I have described comprise about 98% of the testing performed for air concentrations, especially for real estate transactions/sales.
