 Dosimeter-radiometer individual DKG-21


9306 UAH

DKG-21 kit

Dosimeter-radiometer is intended for measuring ionizing radiation including dose rate of gamma-radiation, accumulated dose. Additionally the functions of clock and alarm clock, blocking (through the personal Computer) of hand shutdown of power supply are realized in a dosimeter. A dosimeter also shows discharge of power supply elements and performs the periodic self testing of power supply elements and detector. In a dosimeter the values of threshold levels for dose rate of gamma-radiation (default value: 1 mkSv/h) and accumulated dose are programmed. A dosimeter is given signal of two tonalities at exceeding of the programmed threshold levels.

A dosimeter is used for dosimetric survey on industrial enterprises, on the enterprises of atomic energy, in physical laboratories, in establishments of health protection, and also by a inhabitants as an electronic direct reading dosimeter for round-the-clock control of the dose loadings on a man. A dosimeter can be used as in composition the automated systems of individual dosimetric control ASIDC-21, so as an autonomous device.

A dosimeter is a very compact (it is possible to carry in a purse or breast pocket or special cover which supply with device) and light device, having a large term of work. In a dosimeter is realized possibility of record of measurings results in the energyindependent memory and subsequent transmission of measuring results (on a communication IR-channel) in the personal computer for an analysis (on a computer the special software which is acquired separately from a dosimeter must be set). Device submitted to the State Register of measuring instruments of Ukraine, so in the case of perform of the official measuring it's subject a periodic check with frequency not rarer than 1 time per a year.
