放射剂量测量的远程控制和数据处理

目的 解决中子-γ混合辐射场只能近距离测量与测量人员因不能远离辐射场而可能受到泄漏中子和γ射线照射的问题，并提高测量效率和精度。方法 开发并利用远程控制技术，通过深入剖析6517A静电计中固化的各种控制、采样和通讯命令，利用计算机通过RS-232串行通信接口远程对剂量仪进行控制，在测量完成的第一时间取回测量数据并可通过网络共享这些数据。结果 通过计算机编程，首次实现本地计算机对6517A静电计的完全自动控制，并通过远程计算机对本地计算机的控制来设置并驱动6517A静电计完成剂量测量任务，实现人员对仪器的异地操作。剂量测量全过程不需要测量人员到现场，从而使测量人员免受泄漏射线的照射。结论 本课题首次将远程控制的概念引入以前一直只能近距离进行的放射剂量测量领域，在保证工作质量的同时保护了测量人员的安全与健康。

Remotel control and data processing for measurement of radiation Dose

Objective\ To protect the workers from the reactor radiation and to improve the accuracy and efficiency of neutron dose measurement. Methods\ With the application of remote control technology,a remote control and automatic measurement system for radiation dose measurement(especially for neutron dose) was set up.A Model 6517A electrometer was operated all automatically over RS-232 serial interface using SCPI commands with a computer. Results\ The workers could stay far from the reactor and be able to control the protable computer in site though internet or LAN and then to control the 6517A electrometer to implement the dose measurement.After the measurement,the data were transferred to the remote computer near the workers and shared by many experts at the first time through the net. Conclusion\ This is the first time that the remote control technology is applied in radiation dose measurement,which has so far been considered can only be performed at a near place.This new system can meet the need of neutron radiobiology researches as well as of the safety and health of the workers.
