Description
There are currently three ongoing efforts to use Silicon PIN diodes as the beta detectors in beta-gamma systems used for radioxenon measurements [1,2,3]. The high resolution that these detectors have demonstrated for conversion electron have shown that they can significantly reduce the minimum-detectable-concentrations for the two meta-stable isotopes 131mXe and 133mXe. Additional physics signatures can be elucidated as triple and greater coincidence between, beta-particles, CE, gamma-rays and X-rays, that were summed in the past using standard beta-gamma detectors [4]. This poster will discuss the impacts to fielded systems and lab operations and the potential reduction in the MDC’s for the four radioxenon isotopes that these new detectors can achieve. 1.
