Recent surveys confirm high levels of U.S. nuclear support
Surveys have consistently indicated that public support in the United States for the use of nuclear energy has been increasing in recent years. Four recent surveys continue to suggest that near-record-high numbers of Americans support nuclear energy. However, the survey results differ—sometimes widely—in the details of their findings.

Low noise silicon avalanche photodiodes (APDs) with ultra thin surface dead layers have been developed for detecting tritium beta particles. Unlike the present windowless proportional counters and liquid scintillation techniques this alternative requires no liquid or flowing gases and has the reliability and compactness of solid-state detector technology. We have carried out detector research to study and optimize the physical and electrical properties of APDs for nuclear spectroscopy. A particular emphasis has been placed on reducing the noise and surface dead layer of large area avalanche photodiodes (1 cm diameter) in order to maximize the quantum efficiency for detecting low energy betas, as well as to investigate the effects of changing temperature, bias, and leakage current on avalanche gain, signal-to-noise and tritium detection quantum efficiency.
