Aluminum-covered and cadmium-covered Solid-State Track Recorders (SSTR) consisting of pre-etched mica and asymptotically thick 235U foils have been used to monitor the fast-neutron dose received by personnel at the Zero-Power Reactor (ZPR) facilities

The half-life of $^{230}\mathrm{Th}$ was measured by the specific activity method. Alpha counting was done in a low geometry counter whose geometry factor was calculated from its dimensions. Sample weights were determined by isotopic dilution. Measur

Solid-state track recorders (SSTR) of muscovite mica have provided absolute fission rates and fission ratios for 235U and 238U in ZPR-6, Assembly 5. The results agree well with diffusion theory and...

Rapid determination of track densities in dielectric plastics is desirable for many experiments. A fast counting system similar to that described by Cross and Tommasino has been built for use with thin polycarbonates exposed to fission fragments. Exp

Measurements of σf(238U)σf(235U) were primarily carried out in the “plateau”-range at 2·5 MeV. Gas scintillation counters and the time-of-flight technique were used. Four different methods were employed for mass assignment. The measured values
