WebThis study has been therefore performed to investigate a detailed response of a gas proportional counter to alpha and beta particles in the health-related context of detecting them in water (Semkow and Parekh, 2000). ... The alpha-to-beta crosstalk is much smaller in 239-Pu (4.9-6.5%) and nearly negligible in 210-Po (1.2-1.6%). Web15 Mar 2024 · When selecting a preamp, the most important criterion is to match the detector capacitance to the preamp. E.g. Ortec 142PC, Tennelec TC170 and Canberra 2006 are designed for proportional counters with capacitance under 100 pF. Using a preamp designed for higher-capacitance detectors with a low-capacitance counter will result in a … i\u0027m pleased to support you
