title: Calibration of diffusion barrier charcoal detectors using a semi-empirical expression.
abstract: Several calibration settings of diffusion barrier charcoal canister (DBCC) detectors for measuring radon concentration in air were studied. A set of functions and graphs were developed for relations between radon concentration in air and adsorbed activity in DBCC, when calibrated in small chambers. Both the integration time for 10% of DBCC of a batch, and the radon adsorption coefficient for the activated charcoal used in these detectors, were determined. Thus, a semi-empirical expression for detector calibration was applied.
