Theoretical calculation of SSNTD response for radon measurements and optimum diffusion chambers dimensions

The response of some SSNTDs was calculated theoretically taking into consideration the major parameters that affect them. These parameters are related to the behavior of alpha emitters, the detectors types and the used diffusion chambers. The obtained results showed that the response of the filtered CR-39 detector is about 5 times higher than that of the LR-115 detector and more than 6 times higher in case of bare track detectors. This calculation was used to determine the optimum diffusion chamber dimensions with experimental verification for different diffusion chambers. The cup of 3 cm radius and 5 cm height gives a good agreement with the theoretical value.
