Proton beam dosimetry by CR-39 track-etched detector
Background: High and intermediate energy protons are not able to form a track in a solid state nuclear track detector (SSNTD) directly. However, such tracks can be formed through secondary particles created during primary radiation nuclear reactions in a SSNTD. Materials and Methods: The protons with primary energies of 9.6 and 30 MeV available at the cyclotron accelerator with corresponding lo...
متن کاملUranium concentration in blood samples of Southern Iraqi leukemia patients using CR-39 track detector
The simple and effective technique of fission track etch has been applied to determine trace concentration of uranium in human blood samples taken from two groups of male and female participants: leukemia patients and healthy subjects group. The blood samples of leukemia patients and healthy subjects were collected from three key southern governorates namely, Basrah, Muthanna and Dhi-Qar. These...
متن کاملInvestigating Indoor Radon Concentration Using CR-39 Detector; a Case Study of Gachin Dwellings in Hormozgan
Introduction: Radon is a colorless inert gas which decay products are the main component of natural radioactive elements that are naturally produced in under layers of earth crust by decay of radium and uranium. It enters through buildings via gaps and cracks. Radon gas decay products like alpha particle can increase the incidence of lung cancer in human. Since every person sp...
متن کاملA parameterization of nuclear track profiles in CR-39 detector
In this work, the empirical parameterization describing the alpha particles’ track depth in CR-39 detectors is extended to describe longitudinal track profiles against etching time for protons and alpha particles. MATLAB based software is developed for this purpose. The software calculates and plots the depth, diameter, range, residual range, saturation time, and etch rate versus etching time. ...
