The professional wrist dosimeters intended for automatic control of radiation environment and measurement of radiation doses person. They are designed to measure ambient dose equivalent ( ED ) H * (10 ) and the ambient dose equivalent rate ( EDR ) Ĥ * ( 10 ) of gamma radiation in the range of background values up to 5.10 Sv / h in a wide energy range.
In devices DKG- RM1603A (B) and DKG- RM1604A (B) provides for the installation of two alarm thresholds are exceeded, the values of the dose and its capacity to provide a timely warning about the dangers of user exposure. In those cases when the radiation intensity exceeds the upper limit of dose rate measurement is displayed warning sign "OL", followed by an intermittent beep.
The device is able to store in its non-volatile memory to 1000 stories dose , cumulative dose quantity and serial number and pass these values to the computer via an IR link using standard devices exchange with a PC (such as IRDA) for further processing and analysis, and presentation of this information as respective databases or graphics display .
High- sealed housing protects the electronics from mechanical influences. The instrument is designed for harsh and adverse climatic conditions , resistant to fall from a height of 0.7 m onto a concrete floor .
Electroluminescent backlight LCD allows you to use the device at night. Saving power supply makes it possible to measure the accumulated dose to 10 Sv using one battery , the discharge is controlled automatically.
Measuring range dose H * (10) of gamma radiation: 1 mSv / h - 10.0 Sv / h
Dose measurement H * (10) of gamma radiation: 1.0 mSv, 9.99 Sv
Display range equivalent dose of gamma-radiation: 0.01 mSv / h to 13.0 Sv / h
Maximum permissible relative error of DER measurement through the Cs-137 radiation kollimirvannom: ± (15 + 0.02 / H + 0.003H)%
