Kauri na allon boron-polyethylene shine 2cm-30cm. Fannin fasaha nasa shine amfani da fasahar nukiliya don kariyar ionizing radiation. Ana amfani da allon boron-polyethylene don kare neutrons masu sauri na filin radiation na neutron, neutron da filin radiation gauraye na Y a fannin kariyar ionizing radiation, don hana lalacewar radiation da lalacewar da radiation na neutron ke haifarwa ga ma'aikatan aiki da jama'a.
Domin inganta tasirin kariya na boron polyethylene akan neutron mai sauri da kuma magance matsalar da ke tattare da samar da allon polyethylene na boron a kasuwa a kasar Sin, an samar da allon polyethylene mai dauke da boron tare da sinadarin boron na kashi 8%. Dangane da ka'idar kare neutron mai sauri, tunda sauran nauyin neutrons shine 1.0086649U, yayin da na atom na hydrogen (watau protons) shine 1.007825 U [1], nauyin atomic na neutrons yana kusa da na atom na hydrogen. Saboda haka, lokacin da neutron mai sauri ya yi karo da nucleus na hydrogen a jikin kariya, Yana da sauki a rasa kuzari ta hanyar canja shi zuwa tsakiya na atom na hydrogen, rage saurin neutrons zuwa rage saurin neutrons da neutrons na zafi. Da yawan hydrogen da ke cikin jikin kariya, tasirin daidaitawa zai fi karfi. Daga cikin sinadarin hydrogen da ke cikin kayan kariya na neutron da aka saba amfani da su, sinadarin hydrogen da ke cikin polyethylene shine mafi girma, har zuwa 7.92x atoms na IO22 / cm3 na iskar gas. Saboda haka, polyethylene shine mafi kyawun mai daidaita garkuwar neutrons masu sauri. Bayan an rage saurin neutrons zuwa neutrons masu zafi, ana buƙatar kayan kariya masu babban sashin sha na neutron na zafi ba tare da hasken Y mai ƙarfi ba don sha na neutrons na zafi, don cimma manufar kare neutrons masu sauri gaba ɗaya. Saboda babban sashin sha na neutron na zafi na (3840 lL)X10_24cm2[3], kuma yawan kiB a cikin boron na halitta shine 18.98% [3], wanda yake da sauƙin samu, kayan da ke ɗauke da boron suna da kyau wajen sha na neutrons na zafi don kare na neutrons na zafi.
Kariyar hasken Neutron a cikin tashoshin samar da wutar lantarki ta nukiliya, na'urorin haɓaka makamashi na matsakaici (masu girma), na'urorin samar da makamashi ta atomic, jiragen ruwa na ƙarƙashin ruwa na nukiliya, na'urorin haɓaka magunguna, kayan aikin maganin neutron da sauran wurare.
