Radonova, at the forefront of intercomparison tests
Radonova is an ISO 17025 accredited laboratory. This means that the laboratory must participate regularly in intercomparison tests organized by national authorities such as PHE in the UK, BfS in Germany, and SUPSI in Switzerland
What is an intercomparison test?
These are tests that expose detectors to a reference level set up by the calibration laboratory. Then, results are compared against the reference level and statistical analysis is conducted. The test covers both precision and accuracy.
How does it work?
The test organization brings together detectors from participating laboratories. We always send dozens of detectors from Radonova, which we randomly select from our stock. This guarantees our impartiality.
The detectors are then placed in a sealed room/rooms where the radon level is known beforehand and maintained at the same level for the duration of the test. The process is repeated in different chambers with different levels of radon. Most of the time, measurements are made in three different environments with radon levels:
- between 200 and 1600 kBqh / m³
- greater than 1600 kBqh / m³
- less than 200 kBqh / m³
