Automated Daily EPD Work Controls at LANSCE


J. Wenzel, B. Campbell, J. Weber


Los Alamos National Laboratory and Gutierrez-Palmenberg, Inc. have developed highly integrated Windows compliant applications to automate the as low as reasonably achievable (ALARA) program for the Los Alamos Neutron Science Center (LANSCE) proton accelerator. Radiation safety, operational, and management personnel are networked together with different user permissions. Work activities and radiation doses for 450 radiation workers are reviewed, approved, and tracked online in real time by the Radiation Protection Automation System (RPAS) using Radiation Work Permits (RWPs), Logbook Worksheets, and Siemens Electronic Personal Dosimeters (EPDs). Radiation Control Technicians issue and return EPDs for RWPs. Dose rates and total dose alarm settings from the RWP are automatically set in the dosimeter based on the individual and collective goals and the work area radiation surveys. Daily EPD doses are tracked, summed, compared to RWP and group goals, and displayed with work activity worksheets and monthly TLD doses to ensure all ALARA goals are continuously overviewed. RWP goals can be updated as needed as the work activity progresses. Personnel and TLD data are updated as needed for all workers using queries from labwide medical databases. Typical work history and exposure data will be presented and analyzed.
