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.
描述了TS-16N固态核径迹探测器作为α发射体快速放射自显影片成像介质的可行性。尽管需要稍长的蚀刻时间，但该探测器上放射自显影图像的对比度被证明优于CR-39探测器，作者之前曾报道过CR-39探测器在宏观放射自显影方面的性能。这两种不同类型探测器的分辨率几乎彼此相当。通过试验进行的放射自显影证明，该探测器可用于研究体内沉积的α发射体的代谢和剂量测定。随着进一步研究，该探测器的固有特性，如低本底或高灵敏度，应能扩展径迹蚀刻成像技术的应用领域，如快中子射线照相术。
