Sensitivity determination and optimisation of a cylindrical diffusion chamber, for radon measurements, with a CR39 detector

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

“…In Ref. [16] for the (1,4) and (4, 4) chambers, f 2 and f 3 are unknown, therefore it seems comparison between these values with Refs. [19,20] is incorrect.…”

A Monte Carlo study of radon detection in cylindrical diffusion chambers

“…Many different monitor geometries have been proposed, but the most common is a cylinder of dimensions around 100 mm, with the detector at the base; the range in air (at standard atmospheric pressure) of the highest energy alpha particles considered here is about 85 mm. For NTDs it is common to refer to an ''effective volume'' within the cylinder [Nikezic et al, 1996;Sima, 2001]; only the alpha particles from this volume will be detected.…”

Radon Monitoring Devices Based on Etched Track Detectors

“…Since the mathematical formulas are complicated, this is beyond the scope of the present book. Most recently (Nikezic et a/., 1996), the Monte Carlo method was applied for the determination of the response of diffusion sampler type radon dosimeters. It should be mentioned that plate-out considerations are invalid in practice, because accurate values of the diffusion coefficients are unknown without elaborate measurements of the size and activity distributions of the aerosols (Fleischer et a/., 1984).…”
