“…There is a similar concern that mass distribution of spontaneous fission fragments from samples of lime was observed [11]. It should also be noted that nuclear track detectors (NTDs) of polymer, pristine or thermally treated, or glass and mica have already been applied to many studies of the detection of the nuclear fission products and the registration properties of these fission products or lighter particles, e.g., alpha particles in those detectors, as reported by several research groups [12][13][14][15][16][17][18][19][20].…”

“…, of thermally annealed CR-39 polymeric detectors, where V B and V T are the bulk and track etch rates, respectively, is enhanced significantly for fission fragments, whereas it is decreased greatly for alpha particles [12,14,20,23]. Additionally, fission tracks formed at an angle less than the critical angle are not revealed because the normal surface advances faster than the etch rate along the track.…”

Abstract:One of main requirements in applied nuclear physics is the need of a detector capable of detecting and differentiating different particles. Thus, the fission products from a 252 Cf radioactive source, after about 12 half-life periods of alpha decay, are registered using virgin and annealed CR-39 polyallyldiglycol carbonate (PADC) films. In the case of virgin CR-39, a single peak appears corresponding to the heavy group of these products, while the other peak related to the light group is obscured. The annealed CR-39 detectors, on the other hand, were demonstrated to be highly sensitive to the fission fragments, and as a result we have observed the characteristic twin peaks of fission fragments from that radioactive source.

The present paper describes the development and applications of nuclear track detection technique in Pakistan. Pakistan entered in the field of nuclear tracks in early 1970s when it was still quite new. Highlights of successes of different Pakistani laboratories, working on nuclear tracks, achieved on their own or in collaboration with similar centers in the world are described briefly. The robust features of this investigation are the comprehensive investigation of the addressed research, analysis and review of results, and discussions with the perspectives of applications and new research directions. Further analysis of the published results by the present author and some new results are also presented. This paper portrays a comprehensive picture of the nuclear track detection research and technology in Pakistan and can be useful for a similar development in any country around the globe

In this paper, the previous modeling of protons and alpha particles tracks depth in CR-39 nuclear track detectors was extensively extended to describe tracks of heavier ions. These ions include deuteron, lithium, boron, carbon, nitrogen and oxygen. Based on a compilation of published experimental results related to these ions, a set of empirical fitted model parameters is obtained for each type of ion. The A dependence of these model parameters is obtained.
