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

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

“…The (1.5, 9.5) chamber was made of aluminum to prevent the entrance of radon through the chamber body and the (4, 6) chamber doped with carbon that absorbs some radon atoms from the effective volume around the detector. It is clear that the obtained values from our work have a good agreement with the experimental values [10].…”

“…The calculated CR-39 responses were listed in Table 3 and compared with the corresponding theoretical and experimental values [10]. The (1.5, 9.5) chamber was made of aluminum to prevent the entrance of radon through the chamber body and the (4, 6) chamber doped with carbon that absorbs some radon atoms from the effective volume around the detector.…”

“…[9,10], the critical angle was considered the same for all particles resulted from radon and its progeny, but the critical angle based on relation (14) for various nuclei is different. …”

“…where K T is the total detection response of the filtered track detector and can be obtained using the following equation: (V/S)e S i is the volume to the internal surface area ratio of the diffusion chamber which is valid for all geometries and K i p is given as follows [3,7,9,10]:…”

“…The given detector is CR-39, because it has a wide energy window for alpha particle's registration (up to 40 MeV) [10]. 2.…”
