Computer-aided personal radiation monitoring system (APRMS)

Purpose:
automated execution of personal radiation monitoring (PRM) in companies

APRMS provides:
data receipt from personal radiation monitoring equipment; centralized storage of personal radiation monitoring information; processing and output of personal radiation monitoring information.

APRMS is a functional structure which include measuring equipment, data-computing network, communications, and software for automated personal radiation monitoring.

APRMS structure:

  • "Routine monitoring" subsystem — routine personal radiation monitoring of external irradiation.
    "Routine monitoring" subsystem supports the following equipment:
    TL (thermoluminescent) radiation monitoring systems (readers RE-1, RE-2000), Harshaw.
  • "Operating monitoring" subsystem — operating personal radiation monitoring of external irradiation.
    "Operating monitoring" subsystem supports the following equipment:
    all-purpose reader for direct reading electronic dosimeters, intended for individual entrance in/exit out of controlled-access area АDR-101;
    direct reading electronic photon and neutron dosimeters:
    RAD-72    /Rad52/62S (readers АDR-101, ADR-1, -85, -285);
    direct reading electronic photon and neutron dosimeters:
    DMC-2000S    , DMC2000GN, DMC2000XB, DMC2000X (readers LDM 2000,  LDM 220).
  • "BRS" subsystem — information, routine and operating monitoring of internal irradiation based on "Body radiation spectrometer" measuring complex.
    "Body radiation spectrometer" subsystem supports the following equipment:
    gamma-radiation spectrometer SKG -АТ1316А "Control BRS "
    gamma-radiation spectrometer SKG -АТ1322 "Iodine BRS "
    gamma-radiation spectrometer "Measurement BRS "
    scintillator and semiconductor gamma-radiation detectors manufactured by Ortec, Canberra, AtomTex.

"Body radiation spectrometer" software is an integral part of internal irradiation monitoring software SW NPP APRMS. "BRS" software is intended for radionuclide content measurement in body, lungs and thyroid of a human being. "BRS" software is intended for the use of NPP personnel internal irradiation dose rate monitoring methods (measurement methods). The software is connected with personnel database and BRS database. Software output allows to calculate internal irradiation dose using database tools.
