该系统满足严格的核资格要求, 如辐射高剂量, 温度, 湿度, 电磁兼容/EMI, 以及第三类软件。
Specifications
Detector | Dual Ion chamber. LND501 and LND50343 to cover range 0.1mR/Hr to 100R/Hr.
Compared with GM tubes, which have 5×10^10 counts limit, the Ion chambers have a much longer life and higher reliability. |
Detector circuit | The radiation dose test detector signal will transmit to measurement unit via balanced-line transmission. |
Check source | Check source with motor drive mechanism.
10uCi Cs137 is built into each detector box. A motor moves the check source close to the detector to check the response/calibration of detector. |
Measuring Module | NIM double width module, built using a real-time micro-controller. |
Alarm Module | NIM signal width module will provide all the relay and local audible & visible alarm. |
Remote module | NEMA type 4 box module with alarm indication, audible alarm, exit sign. It communicates with measuring unit via RS485. |
Central computer with Data trending, data logging. | Designed in VB.net. |
Qualification | Radiation Dose for detector module
Temp/Humidity: 50ºC/95%RH EMC/EMI Software qualification: Category III software |
