Description

A prototype of LaBr3:Ce in situ gamma-ray spectrometer for marine environmental monitoring is developed and applied for marine measurement. A 2-inch LaBr3:Ce scintillator is used in the detector, and a digital pulse process electronics is chosen as the pulse height analyzer. Both Ethernet and RS-485 are implemented as the data and control interface of the system, and a GPS module is also built-in to work with the GIS. From previous Monte Carlo simulation result, it is indicated that the self-activity in LaBr3:Ce deteriorates the MDAC, but it's still a potential good choice because of its high energy resolution. The preliminary test result of this prototype is introduced in details.
