Optical appearance of alpha particle tracks in CR-39 SSNTD
A ray tracing method based on geometrical optics was used to study the tracks from alpha particles with different energies and with an incident angle of 50 . The transmission operation mode of the microscope is simulated. Considering the distribution of light intensities from the tracks, the mean and the 80% percentile gray levels from real experiments are proposed as quantitative variables to ...
متن کاملOptical appearance of alpha-particle tracks in CR-39 SSNTDs
The optical appearance of etched alpha-particle tracks in CR-39 SSNTDs under the transmission mode of the optical microscope were studied. The mean grey levels revealed using a digital camera installed on the microscope, together with the major and minor axes were systematically determined for tracks from alpha particles with different incident energies and angles. The grey level properties for...
متن کاملAlpha-particle radiobiological experiments using thin CR-39 detectors.
The present paper studied the feasibility of applying comet assay to evaluate the DNA damage in individual HeLa cervix cancer cells after alpha-particle irradiation. We prepared thin CR-39 detectors (<20 microm) as cell-culture substrates, with UV irradiation to shorten the track formation time. After irradiation of the HeLa cells by alpha particles, the tracks on the underside of the CR-39 det...
متن کاملA New Method to Determine the Maximum Value of the Track Length of Alpha Particle in CR-39 Detector
The aim of this paper is to determine the maximum values of the track length (Lmax) of alpha particles in Nuclear Track Detector (type CR-39) using a new method by taking the relation between the etching time and the diameter square of alpha particle with different energies at constant bulk etch rate VB (1.45 μm/hr) by using TRACK_TEST program from Brun et al. function and Yu et al. function. U...
متن کاملDetermination of alpha-particle track depths in CR-39 detector from their cross-sections and replica heights
A challenging task in the application of solid-state nuclear track detectors (SSNTDs) is the measurement of depths of the tracks. One approach involves breaking and polishing the side of SSNTDs to reveal the cross-sections of the tracks for direct measurements. Recently, surface profilometry was used to measure the heights of the replicas of alpha-particle tracks to give the track depths. In th...
