Abstract: Background: The upgrade project of Hefei Light Source (HLS) was started in 2009. Improving radiation monitoring system is an important part of the upgrade project. Purpose: This study aims to design and implement a web-based dynamic release system for a real-time and remote multipoint radiation monitoring of HLSII. Methods: Data acquisition and storage section were implemented by using LabVIEW, 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 system based on Brower/Server. Results: This system is easy to operate and has run stably for several months, meeting the designing requirement. Conclusion: With this system, real-time monitoring and historical data query can be more efficient and convenient for administrators and users. It also provides a good reference for other nuclear devices in the aspect of radiation monitoring data opening to the public.
