The analytical calculation of the detection response and optimum dimensions of the conical diffusion chambers with a CR-39 detector

The solid state nuclear track detectors (SSNTDs) have been used in diffusion chambers for long time measurements of radon gas concentration. There is a direct proportion between the number of traces on SSNTDs and the activity concentration of radon with proportion coefficient that is called calibration coefficient (detection response). In this paper, partial and total detection responses of a CR-39 solid state detector in a conical chamber have been measured analytically and experimentally. Using these solutions, calibration coefficients have been drawn in terms of different dimensions of conical chambers. The results are compared with the experimental results of this work and the others.
