Theoretical analytical calculations of the radon registration have been performed for the solid state nuclear track detectors (SSNTD) LR-115 Type II (peliculable) produced by Kodak-Pathé (France). Known and measured properties of LR-115 together with the well established etching theory using “Huygens principle” were used to carry out these detailed calculations for different types of exposure devices for indoor room and outdoor soil measurements.

The results of these modeling calculations are compared with experimental calibration measurements and show good agreement.
