Hefei Light Source (HLS) is a large scientific facility with a high energy storage ring to storing circling moving electrons, which produce SR. The radiation field around HLS is quite different from that around other nuclear facilities. In order to improve the performance of the light source, an upgrade project was started in2010, of which, the improving radiation monitoring system is an important part.Based on the original monitoring system, this study aims to design and implement a web-based system for a real-time and remote multipoint radiation monitoring of HLSII. The radiation monitoring system which is used in area and environment monitoring, is divided into several parts with relevant alarm threshold. In addition, the system was integrated into EPICS database with the interface. Through this system, we can analyze the radiation monitoring results with the accelerator operation data.HLSII radiation monitoring system is consisted of data acquisition module and dynamic release subsystem. Based on the Mini-DDL(Mini Digital Data Logger), data acquisition and storage section were implemented by using Lab VIEW. Moreover, the system was integrated into EPICS database with the interface designed by CA Lab. Java combining with Java Server Page (JSP) technique was adopted to complete the design and implementation of the data query subsystem based on Brower/Server.The easy-operated system is running stably for several months, meeting the designing requirement. With this system, real-time monitoring and historical data query can be more convenient for administrators and users. The radiation monitoring system not only can be used to analyze the radiation field, but also provides valuable information for operating personnel. After finishing the adjustment of the machine, the environmental radiation monitoring data can be open to the public. Moreover, it provides a good reference for the construction of other radiation monitoring network system.
