1 DOSIMETER DESCRIPTION AND OPERATION

1.1 Purpose of the dosimeter

The personal gamma radiation dosimeter ДКГ-05Д ФВКМ.412113.005 (thereafter,

dosimeter) is produces in accordance with the requirements of ТУ 4362-010-31867313-01.

The dosimeter is used both with the УС-05С reader and КЗУ-27 cassette charger and

independently (for routine, operational, and accidental monitoring of individual doses) as well as

a part of the computer-aided dosimetry monitoring system at facilities and organizations, when

handling ionizing radiation sources, including nuclear-powered vessels.

The dosimeter is designed to wear it on the personnel clothes. The dosimeter is intended

to measure the personal gamma radiation dose equivalent
