“吸盘3”号挖泥船核子密度计改进设计

The Improved Design of Nuclear Density Meter for “Xipan 3”Dredger

针对挖泥船核子密度计普遍存在精度偏低,易受环境辐射影响,辐射防护标准陆地化的问题,在分析挖泥船具体施工条件的基础上,依据测量精度、环境辐射屏蔽、辐射防护标准对挖泥船核子密度计进行改进设计。改进后在"吸盘3"号挖泥船上应用表明,测量精度达到设计要求,消除了环境辐射对测量结果的影响,辐射防护效果优异。

The nuclear density meter for dredger has problems of low precision, susceptible by environmental radiation and adopting the radiation protection standards for land. After analzing the specific construction conditions of the dredger, the design of nuclear density meter is improved for dredger according to the requirements of measurement precision, environmental radiation shielding and radiation protection standards. The application of the meter in Xipan 3 dredger shows that the measuring accuracy reaches the design requirements, the effect of environmental radiation on the measurement result is eliminated, and the radiation protective effect is excellent.
