                含硼聚乙烯中子防護材料

                含硼聚乙烯中子防護材料Boron polyethylene是一種添加硼的聚乙烯HDPE復合屏蔽材料,硼含量根據不同需求定量添加2%~70%。除金屬硼外,還可添加碳化硼、三氧化二硼、碳化鋰、金屬鉛粉等來增強聚乙烯板的防護中子屏蔽伽馬射線的能力。其中硼對中子的反應截面較大,可將快中子和熱中子慢化為慢中子,而聚乙烯是高氫材料,氫元素對慢中子有明顯的減弱能力,額外添加鉛粉,鉛元素對伽馬γ輻射線有很好的屏蔽能力。Among them, boron has a large reaction cross-section to neutrons, which can slow down fast neutrons and thermal neutrons into slow neutrons, while polyethylene is a high-hydrogen material, and hydrogen has obvious attenuation ability to slow neutrons. With the addition of lead powder, lead has a good shielding ability to gamma-ray radiation.

                含硼聚乙烯中子防護材料Boron polyethylene已廣泛應用于核輻射、中科院、航空、醫療等領域用于中子束準直器、核試驗用樣品罐、中子捕及器及核反應堆的控制棒材料。
