摘要
Abstract
Large area portable surface contamination monitor is suitable for searching the hot point, especially in the situations of large contamination area such as work site radioactive monitoring, nuclear facility decommissioning or nuclear emergency response. This paper focus on beta radioactive surface contamination. Through researching upon the detector which is made of large area plastic scintillation coupled with fibers, the first large area plastic scintillation surface contamination monitor was established. The effective area of detector reaches 1 200 cm2. The verifying experiments indicates that the detection efficiency to 90Sr-90Y plate source comes to 7%. The results show this kind of detector is competent for beta radioactive surface contamination. This work laid a foundation for research and development of the relative instrument.关键词
