THE EFFECT OF RADIATION ON SOME PHYSICAL PROPERTIES FOR CN-85 NUCLEAR TRACK DETECTOR

Abstract

In this research, some properties of the nuclear tracks detectors were studied, samples of CN-85 were irradiated with an alpha particle that emitted from americium (Am241) for (3, 5, 10) minutes then etched by using chemical sodium hydroxide (NaOH), the effect of radiation on the thickness of the detectors (CN-85) and on the diameters of the tracks were described in addition to the physical properties in terms of the color of the detector and its transparency for detector, then a comparison study was conducted between the tracts for each the time of irradiation duration for samples of detectors then it was proved The nuclear track detector CN-85, lost its chemical properties when scraped at a temperature of 60°C for half an hour. The radii of the tracks produced by the irradiation were measure foe samples of CN-85 detectors, and it was found that the diameter of the trace increases with the increase of the etching time and the duration of the irradiation. It was also found that the thickness of the detector does not change with the change of the irradiation duration, but it does change with the change of the etching time.
