“…Characteristics of solid state nuclear track detectors were studied by many authers. It is well known that, track size, bulk etch rate and track etch rate are affected by exposing detectors to several types of radiations such as, X-ray, γ-rays, UV and alpha particles [1,2,3,4,5,6]. The two main changes noticed in polymers are [7] : 1) Chain cross linking resulting in an increases of molecular weight because of a large number of free radicals produced in polymer.…”

Studies of CR-39 irradiated with γ-rays, X-rays and alpha particles by FTIR spectroscopy are presented. In this work we make a comparison between the effect of many types of radiation on the sensitivity of CR-39 detector by using the FTIR spectrometer. It was found that,investigated CR-39 is so sensitive for all types of radiation used that was used as a dosimeter for these types of radiation. The determination of alpha particles range in CR-39 plastic recorder is an important parameter in the field of charged particle identification using Solid State Nuclear Track Detectors. In this work the optical denisty of the detector was calculated and then it is used to determine α-range. An over-etched track profile method and a theoretical method derived by Almasi are compared. A good agreement between the three methods used in α-range determination was found.

“…Polyallyl diglycol carbonate, C 12 H 18 O 7 , (CR-39) track detectors is the most sensitive and popular detector for recording alpha particles [1][2][3][4]. Therefore, several studies [5][6][7][8][9][10][11][12][13] have been carried out to determine the main factors which affect the sensitivity and the properties of the CR-39 polymer as a track detector. The passing of alpha particles through CR-39 sample causes ionization for almost all molecules which close to its path.…”

The track etch detector, CR-39, in common use is the most sensitive to recording charged particles. The CR-39 polymer samples were irradiated with alpha particle at different energies (2.17 MeV and 3.95 MeV) and fixed fluence followed by chemical etching with different times (1.50, 3.00 and 6.00 hrs). The formed tracks in CR-39 due to irradiations were visualized by using etching technique. The optical properties of CR-39 polymer after etching processes were studied with ultraviolet-visible (UV-vis) spectroscopy. Moreover, the optical band gap energy was calculated for the different etching times (1.50, 3.00 and 6.00 hrs). The average value of the track diameter of irradiation at 2.17 MeV and etching time 1.5 hr is fairly large compared with its value at 3.95 MeV. This is due to the production of defect levels in the band gap of polymer at the 2.17 MeV. The virgin and 2.17 MeV samples at 3.00 and 6.00 hrs have the same optical behavior resulted in the etching solution at those etching times has reached the end of the alpha particle path and progress in all the directions in the bulk of CR-39 with the same rate.
