Miniature professional dosimeters are designed to measure the ambient equivalent dose (ED) H*(10) and the ambient equivalent dose rate (DER) Ĥ*(10) of gamma and X-ray radiation from 1 μSv/h to 5 Sv/h (DKG-RM1603A) or up to 10 Sv/h (DKG-RM1603V) in a wide energy range. The dosimeters provide the ability to set two independent alarm thresholds for dose and dose rate, the excess of which is automatically accompanied by an audible alarm. In this case, the display of the devices shows the value whose threshold has been exceeded, which ensures timely notification of the user about the radiation hazard. In cases where the radiation intensity exceeds the upper limit of dose rate measurement, the display shows the warning message "OL" and an intermittent sound signal is emitted.
The DKG-RM1603A and DKG-RM1603V dosimeters are equipped with non-volatile memory, which automatically stores up to 1000 history events (measurements of dose rate, accumulated dose, cases and levels of exceeding the set alarm thresholds; 500 MED + 500 ED). Using an infrared (IR) communication channel, information from the non-volatile memory of the device can be transferred to a personal computer for further processing and analysis, as well as presentation in the form of relevant databases within the framework of the personnel radiation dose monitoring and accounting system.
The sealed, shockproof case allows the use of the devices in adverse operating conditions and, if necessary, decontamination of the dosimeters, and the fluorescent backlight makes it easy to read information from the display in the absence of external lighting.
