主 题:Tritium Plastic scintillating fiber array Detector
摘 要:Tritium,a radioactive nuclide discharged by nuclear power plants,poses challenges for *** online monitoring of tritium in water is crucial for real-time radiation data,given its predominant existence in the environment as *** paper presents the design,simulation,and development of a tritium monitoring device utilizing a plastic scintillation fiber(PSF)*** validation confirmed the device’s detection efficiency and minimum detectable *** recorded detection efficiency of the device is 1.6×10^(-3),which exceeds the theoretically simulated value of 4×10^(-4)by four *** shielding,the device can achieve a minimum detectable activity of 3165 Bq L^(-1)over a 1600-second measurement *** to simulation and experimental results,enhancing detection efficiency is possible by increasing the number and length of PSFs and implementing rigorous shielding ***,reducing the diameter of PSFs can also improve detection *** minimum detectable activity of the device can be further reduced using the aforementioned methods.
