中子源屏蔽门射线防护含硼聚乙烯

中子源屏蔽门射线防护含硼聚乙烯是指加硼处理的聚乙烯。纯聚乙烯是硬质、半透明白色蜡状物质，软化温度115℃，易加工成所需形状。密度0.928/cm3，单位体积含氢原子数7.8—8.0×10的22次方个/cm3,含氢量比水多，慢化中子能力比水强，是有效的中子屏蔽材料。含硼聚乙烯用聚乙烯作基体，将碳化硼弥散在其中通过高速搅拌、捏合、塑化、层压而成的含硼聚乙烯板是一种新型的复合材料。

Pure polyethylene is a hard, translucent white wax-like substance with a softening temperature of 115℃, which is easy to be processed into the required shape. The density is 0.928／cm3, the number of hydrogen atoms per unit volume is 7.8-8.0× 10 to the 22nd power/cm3, the hydrogen content is more than that of water, and the neutron slowing ability is stronger than that of water, so it is an effective neutron shielding material.含硼聚乙烯成功用于核电站乏燃料格板、核动力船舶、核对中子辐射、中石油、中科院、研究院、医院以及核反应堆的控制棒材及核屏蔽材料等研究领域，更是作为屏蔽中子，射线，辐射屏蔽吸收的*材料。
