Marine radioactive field monitoring sensor based on NaI (Tl)

There are many deficiencies in traditional laboratory means, which make it difficult to meet the real-time monitoring requirements of nuclear radiation on marine field. In this paper, a radioactive monitoring sensor for marine field was proposed, which is based on NaI (Tl) scintillation crystal, while energy calibration and resolution calibration are conducted by employing a standard radioactive source, and curve fitting is conducted by employing MATLAB. Through the test under seawater in Qingdao wharf, the results are in good agreement with the laboratory test results. (paper)
