In order to address inquiries pertaining to nuclear forensics, our research endeavors involve the formulation of novel methodologies and strategies aimed at enhancing the dependability and precision of this analytical process.<br/>At now, the analysis of microscope pictures is limited to individuals who have received formal training in research methodologies. Given that this analysis relies on the researcher's own aptitudes and competencies, it is evident that several researchers will yield slightly divergent outcomes.<br/>At now, the analysis of microscope pictures is limited to individuals who have received formal training in research methodologies. Given that this analysis relies on the researcher's own aptitudes and competencies, it is evident that several researchers will yield slightly divergent outcomes.<br/><br/>The simulation of fission tracks was conducted using the Monte-Carlo software, GEANT4. This software incorporates various aspects of nuclear fission tracks, including thermal neutron flux, fission cross-section, radiation time, particle size, enrichment, and other relevant physics. The present investigation involves the utilization of Trainer2.0 software to compute the trajectories on our Lexan detector, as well as their corresponding projections. These calculations are based on many physical parameters, including neutron flux, particle size, isotope, and radiation duration. The outcome manifests as a "star" that is positioned at the center of the simulated particle. The entirety of our software is implemented using MatLab programming language.<br/><br/>The simulation of harsh conditions allows for the exploration of novel aspects inside the fission track technique. The simulation provides insights into determining the appropriate sample size for the FTA procedure.<br/>The simulation has the capability to make predictions and may be compared to both the mini-bulk and micro-bulk analyses.<br/>The novel concept of employing penetrating fluorescent colors provides the capability to perform three-dimensional (3D) scanning with our detector, as opposed to the conventional two-dimensional (2D) scanning. In this particular instance, the Dapi marker was employed as an initial approach. It is widely recognized in the field of biomedical research.<br/><br/>This new idea to investigate the FT Star more than just by his projection.<br/>The determination of the source isotope in a given element can be achieved by analyzing the length and distribution of its tracks. This analysis involves examining the shape of the "fission products distribution" as well as the density of impurities present in the source.
