| Abstract | ||
| The study aim determine the energy response of nuclear track detector cellulose nitrate CN-85 with thickness (100µm) for alpha particles emanated from Americium source 241Am of (1µCi) at irradiation time (5 min). The process of the irradiated detectors has been done by using the etchant (NaOH) with normality (5N) and etching temperature (50°C) for different times(0.5-4.5hr). The results led to determine the energy spectrum of alpha particles which the detector responded to with energy range (0.2-4.5 MeV). It has also been found that there was an increment in average of radii tracks with Etching time for all the used energies , it has also been observed that track density change with etching time for the above energies. In addition , we reached at determining the optimum etching times to reveal all formed tracks and also all the used energies and the maximum absorption energy occurs at 1.5 MeV. | ||
