  • Determination of Phoswich detector response using MCNP analysis to enhance Radioxenon measurement

    Creator:
    Lopez, Alejandro Uriel
    Abstract:
    As mandated by the Comprehensive Nuclear Test Ban Treaty (CTBT), the United States (US) is involved in the development and deployment of an International Monitoring System (IMS) for monitoring nuclear explosions. The US system, developed at Pacific Northwest National Laboratory, is known as the Automated Radioxenon Sampler/Analyzer (ARSA). The US...

    system are necessary. Ely et al. (2003) explored the idea of using a phoswich detector for the ARSA

  • Prototyping a triple-layer phoswich detection system

    Creator:
    Duncan, Christopher L.
    Abstract:
    Multi-layer optically coupled scintillation based radiation detectors, known as phoswich detectors, have rapidly evolved in recent years. During the same time, digital signal processing has improved radiation discrimination accuracy and enhanced reliability, while reducing complexity and size of traditional analog signal processing methods. A new generation of high-speed radiation detectors...

  • Progress in the development of a portable phoswich-style skin contamination dosimeter

    Creator:
    Tang, Matthew M.
    Abstract:
    The Code of Federal Regulations (10CFR20.1201) mandates occupational dose limits to the shallow, lens and deep tissue layers. The NRC-accepted procedure of estimating dose to these layers from contamination events is laborious. The current work aims to further the development of a portable phoswich-style skin dosimeter that will operate in...
