Ubunini bwikibaho cya boron-polyethylene ni 2cm-30cm.Umwanya wa tekiniki ni tekinoroji ya kirimbuzi ikoreshwa mu kurinda imirasire ya ionizing.Ikibaho cya Boron-polyethylene gikoreshwa mukurinda neutron yihuta yumurima wa neutron, neutron na Y ivanze nimirasire yumurima murwego rwo kurinda imirasire ya ionizing, kugirango hirindwe imishwarara yangirika nibyangiritse biterwa nimirasire ya neutron kubakozi babakozi nabaturage.
Mu rwego rwo kunoza ingaruka zo gukingira boron polyethylene kuri neutron yihuse no gukemura ikibazo cyuko bigoye kubyara ikibaho cya polyethylene mu bucuruzi mu Bushinwa, hashyizweho ikibaho kirimo polyethylene kirimo boron gifite 8%.Ukurikije ihame ryo gukingira neutron yihuta, kubera ko misa isigaye ya neutron ari 1.0086649U, naho iya atome ya hydrogène (ni ukuvuga proton) ni 1.007825 U [1], ubwinshi bwa atome ya neutron yegereye iya atome ya hydrogen.Kubwibyo, iyo neutron yihuse igonganye na hydrogène nuclei mumubiri ukingira, Biroroshye cyane gutakaza ingufu mu kuyimurira muri nucleus ya atome ya hydrogène, igabanya umuvuduko wa neutron yihuta kuri neutron na neutron yumuriro.Kurenza hydrogene umubiri ukingira urimo, imbaraga zo guhindura zizakomera.Muri hydrogène yibikoresho bikoreshwa muri neutron bikingira, hydrogène ya polyethylene ni yo hejuru, kugeza kuri 7.92x IO22 atom / cm3.Kubwibyo, polyethylene niyo moderi nziza yo gukingira neutron yihuta.Nyuma ya neutron yihuta gahoro gahoro muri neutron yumuriro, ibikoresho byo gukingira hamwe nigice kinini cya neutron cyinjira mumashanyarazi kitagira imirasire yingufu Y irakenewe kugirango ikure neutron yumuriro, kugirango igere ku ntego yo gukingira neutron byihuse.Bitewe nubushyuhe bwo hejuru bwa neutron bwinjiza igice cya (3840 lL) X10_24cm2 [3], kandi ubwinshi bwa kiB muri boron karemano ni 18,98% [3], byoroshye kubona, ibikoresho birimo boron nibyiza cyane kugirango bikingire ubushyuhe neutron.
Kurinda imirasire ya Neutron mu mashanyarazi ya kirimbuzi, kwihuta kwingufu (hagati) kwihuta kwingufu, reaction za atome, ubwato bwa kirimbuzi, kwihuta kwa muganga, ibikoresho byo kuvura neutron nahandi.
