The dosimeters are intended to measure personal dose equivalent and dose equivalent rate x-ray and gamma radiation. They measure dose rate in a wide range and have separate audible and visual alarm. Microprocessor processing and proper background detection ensure high accuracy of dose measurement within the wide dose rate measuring range. The microprocessor controls operation modes over, calculates, outputs data on a backlit LCD and performs self-testing. The nonvolatile memory keeps the accumulated dose and its accumulation history when the dosimeter is off. The dosimeter is calibrated on a water phantom of 30 x 30 x 15 cm according to the ISO4037-3 International standard requirements. The instruments are watertight, electromagnetic and shock proof (fall from 1.5 m).
The dosimeter can operate singly or in a dosimetry monitoring system: dosimeter - reader - PC. The dosimeter connects to the reader via IR channel, and the reader connects to PC via RS232. The dosimeter software is intended to:
- Read/setup personal and serial dosimeter numbers;
- Change dose and dose rate thresholds;
- Disable/enable to change dosimeter thresholds by the dosimeter button;
- Change the dose accumulation interval in the range from 1 to 255 min and evaluate accumulated dose for each time interval within a work shift;
- Save automatically up to 800 dose values in the nonvolatile memory accumulated for the selected accumulation interval;
- Reset accumulated dose;
- Disable/enable to reset accumulated dose by the dosimeter button;
- Save automatically data in the data base and print them.
The operation modes are "Dose ", "Dose rate ", "Economical", "Menu", "Reset dose", "Dose threshold", "Dose rate threshold" and "Data exchange with PC".
