Potential for highly variable/unknown source

terms

Harsh operational environments complicated by

instruments that are:

  • Hard to use, often proprietary
  • Difficult to maintain
  • Competing with other inspector responsibilities

Application of radiation detection to OSI is likely to be challenged by a number of issues including:

Flexibility, and scalability for highly-variable

environments

  • Operating
  • Activity ranges

Ease-of-use

  • Multi-mode acquisition/data display
  • Open for international use, non-proprietary control and
  • utput
  • Supportability
  • Data recording and/or transmission/retrieval including

location

OSI needs mobile gamma detection capability with some key attributes….

As a leveraging opportunity, we are evaluating technology developed for mobile search

  • Our regional security pilot in San

Francisco Bay is field testing detection technologies, advanced communications and reach back

  • Partnership between LLNL, Naval

Post Graduate School and a SF Bay Regional Coalition

Fielded with multiple organizations, the LLNL-developed detection systems have been operational for a number of years

Windows-based (7+) C-Sharp code operating Ortec-

based acquisition hardware (digiBase)

Provides for simple operation

  • Starts/Stops acquisition
  • Reports relative scalar rates and an alarm threshold
  • Tracks GPS location
  • Provides spectral display

— Continuous or limited duration acquisition, clearable to the user,

and can be enabled or disabled

  • Data saved locally w/ or w/o transmission, both data push

and pull available (if networked)

— Saved in ANSI Standard file format for easy import

Operating interface designed for ease of use….
