  • Predicting instrument detection efficiency when scanning small area radiation sources

    Creator:
    Hart, Kevin G.
    Abstract:
    Accurate quantification of radionuclides detected during a scanning survey relies on an appropriately determined scan efficiency calibration factor (SECF). Traditionally, instrument efficiency was determined from a fixed instrument to source geometry. However, as is often the case, the instrument is used in a scanning mode where the source to instrument...

  • Calculation of scanning efficiencies for portable instruments used to detect particulate contamination

    Creator:
    Moss, Stephen Craig
    Abstract:
    Efforts are continually being made in remediation surveys to reduce the time and manpower required to perform work while maintaining the ability to detect low levels of contamination. To this end, organizations are utilizing portable instrumentation in conjunction with global positioning systems (GPS). This combination of technologies allows a surveyor...

  • An exploratory study of an intranet dashboard in a multi-state healthcare system

    Creator:
    Wolpin, Seth E.
    Abstract:
    Introduction: Management of complex systems is facilitated through effective information systems that provide real-time data to decision makers. For example, instrument panels in airplanes ensure that pilots have well-designed feedback concerning the status of mission-critical variables. Problem: While pilots have dashboards for feedback and communication, healthcare executives may be unaware...
