The hz-ii type Haizhou brand radiation dose alarm system device adopts the pre amplification circuit and silicon detector with unique design scheme (other detectors can be selected according to the radiation source level). It has the characteristics of high sensitivity, convenient operation, full-automatic display of information, data storage and over threshold alarm. It can instantly obtain the X radiation source dose rate (Gy / h and SV / h can change the display information )In addition, the total dose (SV) can also be used as a free online radiation monitoring system software to maintain real-time monitoring system and over threshold safety alarm.
The instrument consists of GM tube detector or semiconductor material detector, switching power supply principle, counting display information and control panel, front amplifier and main charging and discharging circuit, alarm lamp, etc. The camera is connected with the server by a 15m cable through the forming circuit, and the server maintains the dose rate measurement and alarm through the power circuit such as the voice divider, timing execution counting, alarm, etc. The measurement time is 1 second for fast gear and 3-60 seconds for slow gear, which can be selected according to the dose rate size.
The function key of the control panel can set the threshold value in the middle of 0.25 Gy / h5gy / h. When the dose rate exceeds the threshold value, the instrument and equipment will generate the light effect and sound alarm and automatically save and store them. You can check the record to find the historical time over threshold alarm value. It is widely used in radioactive material waste warehouse, industrial production nondestructive testing, hospital outpatient knife treatment, radionuclide application, irradiation, hospital outpatient X-ray diagnosis, cobalt treatment, nuclear power plant and other radioactive material sites, to remind the staff that the radioactive material or ray installation has been in work or leakage, so as to avoid radiation hazards. For the ray device, in addition to the over threshold alarm, according to the customer's necessary requirements, we can design a scheme to keep the door data signal to keep the door interlock function.
