【 摘 要 】

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.
