ABSTRACT: Feasibility of TS-16N solid state nuclear track detectors for an imaging medium of rapid autoradiography of alpha-emitters is described. Though a little longer etching time was required, the contrast of autoradiographic image on this detector proved to be superior to CR-39 detectors whose property for macroautoradiography was previously reported by the authors. The resolutions of these two different type detectors were almost equivalent to each other. The autoradiography taken by way of trial proved that this detector could be used to study metabolism and dosimetry of internally deposited alpha-emitters. With further study, the inherent properties of this detector such as low background or high sensitivity should extend the field of track etch imaging technique such as fast neutron radiography.

ABSTRACT: The characteristics for alpha-particle recording of CR-39 plastics was studied for practical use. Sample detectors were irradiated with alpha-particles at normal incident angle. The energy was varied from 1.29 to 5.48 MeV. Tracks of alpha-particles could sufficiently be recognized through the etch pit observation with 1 hour etching in 30% solution of NaOH at a temperature of 70 degrees C. The etch pit diameter decreased almost linearly with the energy of alpha-particles at the early stage of etching, which suggested the possibility of the estimation of alpha-particle energy. The energy resolution was evaluated from the FWHM of the measured distribution of etch pit diameters and found to be about 1.8 MeV for 1, 2 and 3 hour etching.
