A chamber to test the response of radon detectors to changing environmental conditions

Research output: Contribution to conferenceOtherpeer-review

Abstract

Radon risk assessment is carried out with accurate measurements withactive or passive instrumentation. All radon detectors must be calibratedand tested using a radon chamber containing a known concentration of radon produced by specific sources of 226Ra. Some of the chambers can alsobe used to test the response of detectors as a function of environmental conditions. In this case, it can be inferred a calibration curve with respect to changing of the parameter considered. For this aim, a new chamber radon was designed and realized to perform both calibration of instruments and to study the detector response in a large range of variation of the environmentalparameters (pressure, 700 - 1100 mbar; temperature, 5-50 ◦C; humidity, 10-90%). The experiments conducted to study the influence of environmental parameters on the detector response, in terms of variation of radon concentration and equilibrium factor, have shown flexibility and easeof use of the chamber.
