Alpha particle registration with SSNTDs

Solid state nuclear track detectors (SSNRDs) are frequently used as integrating detectors for alpha particles, e.g. in Radon dosimetry, Uranium prospection, and in nuclear and solid state physics. Further, alpha particles from radioactive sources or accelerators are especially suitable for fundamental investigations on nuclear track detection characteristics of polymer materials. In view of this widespread interest, the Organizing Committee of the 9th International Conference in Solid State Nuclear Track Detectors (9th ICNTD) taking place from Sept. 30 to Oct. 6, 1976, at the Gesellschaft fuer Strahlen- und Umweltforschung (GSF), Neuherberg, asked the GSF-Institut fuer Strahlenschutz to organize under the sponsorship of the 9th ICNTD for its participants an International Alpha Particle Registration Intercomparison with Solid State Nuclear Track Detectors (ALRIT). In this report the full results of all ALRIT-participants are reproduced, who returned their data before the conference. A discussion of these results and more details of the actual irradiation conditions are presented in the proceedings of the 9th ICNTD (to be published). (orig./ORU)
