Personal dosimeter DKG-05D (gamma radiation)

Description of operation

Routine use of the dosimeters DKG-05D in the context of Automated System for Personal Dosimetry (ASPD) at facilities having a lot of radiation workers is automated as high as possible: a worker should withdraw any dosimeter from the charging unit at the entrance to the control area, insert it into the slot of the reader and than dial his/her personal ID (clock number). The reader reports the worker’s ID and dosimeter number to the computer. ASPD software checks the worker’s access code, assigns the dosimeter to the worker and sets the dose alarm threshold of the dosimeter according to (equal to) the dose limit allowed for this worker.

When worker exits the control area, he/she should again insert the dosimeter into the reader. Dose received by the worker is transferred to the computer. In case received dose is higher than the dose limit allowed for this worker, the reader will transfer the whole dose history (accumulation of dose with time).
For facilities with small number of radiation workers this procedure is to be performed by the radiation supervisor / technician.


  • measurement of personal dose equivalent Hp(10) (PDE);
  • measurement of personal dose equivalent rate Hp(10) (PDER).


  • 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”;
  • the dosimeter can store in the built-in memory the dose history including up to 1900 measurement results;
  • two-way communication with the reader via IrDA или infrared interface;
  • unauthorized person can not compromise measurement results by turning the dosimeter off, erasing memory or changing settings; this can be done using work station (computer) only;
  • 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;
  • “intellectual charging” feature extends battery life time;
  • self-test for electronics and for dosimeters;
  • illuminated display.
