List of Approved Alpha Track Manufacturer and Labs:

Alpha track detectors use a small piece of special plastic or film inside a container to provide an average of radon levels over the full duration of the testing period. The package is opened to start the test and when the test is completed it is sent to the laboratory for analysis. The radon exposure duration can be from 10 days to 12 months. Verify with the manufacturer the suggested duration for each device.

The detectors need to be analyzed by the lab which provides them to you.

List of Approved Electret Ion detectors

Electret Ion Chambers consist of a special plastic canister (ion chamber) containing an electrostatically charged disk detector (electret). This type of detector may be deployed for 48 hrs to 12 months.

List of Approved Continuous Radon Monitor Manufacturers:

Professional-grade Electronic Radon Monitors record real-time continuous measurements of radon gas over a series of minutes and reports the results, generally in hourly increments. These devices will have methods for storing, displaying, and retrieving the data logged by the device and may also have the ability to measure and track additional environmental parameters above and beyond the radon concentration such as temperature, barometric pressure, and relative humidity, and they often have onboard motion sensors.
These professional grade devices need to be annually calibrated by the manufacturer.
