Calibration coefficient for radon measurements with LR-115-II track detector in different types of diffusion chambers

Theoretical calculation on CR-39 response for radon measurements and optimum diffusion chambers dimensions

“…The value of the fraction of radon progeny f i is not known and it depends on the chamber dimensions, shape and probably on the conditions existing during exposure. Determination of f i requires a measurement of the radial track density distribution on the detectors, which implies a readout by an optical microscope which is difficult and time consuming [17,18].…”
