Dosimeter can be used both for personal monitoring of gamma radiation, and as part of the radiation monitoring system within the organization.

Using of the dosimeters DKG-05D in Automated System for Personal Dosimetry (ASPD) at facilities having a lot of staff.

Worker should get any dosimeter from the charging unit at the entrance to the control area, insert it into the slot of the reader and enter personal ID. The reader checks workers ID and ASPD software assigns the dosimeter to the worker and sets the dose alarm threshold of the dosimeter according to the allowed dose limit.

Worker should again insert the dosimeter into the reader when exits the radiation control area for transfer measured values to ASPD.

For facilities with small number of radiation workers this procedure is to be performed by the supervisor.

DKG-05D features:

  • complies with IEC 61526 Ed. 2 (2005-02) "Radiation protection instrumentation. Measurement of personal dose equivalents Hp(10) and Hp(0.07) for X, gamma and beta radiations. Direct reading personal dose equivalent and/or dose equivalent rate dosemeters"
  • storing in the built-in memory up to 1900 measurement results
  • two-way communication with the reader
  • measurement results, memory and settings protection
  • continuous setting of audible and visual alarm thresholds for PDE and PDER within full measurement range
  • charging unit for 1 dosimeter, 28 dosimeters or 56 dosimeters
  • "intellegent charger" extends battery lifetime
  • self-testing feature
  • illuminated display
