Botenya ba boto ea boron-polyethylene ke 2cm-30cm. Tšimo ea eona ea tekheniki ke ts'ebeliso ea theknoloji ea nyutlelie ea ts'ireletso ea mahlaseli a ionizing. Boto ea boron-polyethylene e sebelisetsoa ho sireletsa li-neutron tse potlakileng tsa tšimo ea mahlaseli a neutron, neutron le tšimo ea mahlaseli a tsoakiloeng a Y tšimong ea ts'ireletso ea mahlaseli a ionizing, ho thibela kotsi le tšenyo ea mahlaseli e bakoang ke mahlaseli a neutron ho basebetsi ba mesebetsi le sechaba.
E le ho ntlafatsa phello ea tšireletso ea boron polyethylene ho neutron e potlakileng le ho rarolla bothata ba hore ho thata ho hlahisa boto ea polyethylene ea boron khoebong Chaena, boto ea polyethylene e nang le boron e nang le boron e nang le boron ea 8% e ile ea ntlafatsoa. ​​Mabapi le molao-motheo oa tšireletso ea li-neutron tse potlakileng, kaha boima bo setseng ba li-neutron ke 1.0086649U, ha ba liathomo tsa haedrojene (ke hore liprotheine) e le 1.007825 U [1], boima ba athomo ea li-neutron bo haufi le ba liathomo tsa haedrojene. Ka hona, ha neutron e potlakileng e thulana le nuclei ea haedrojene 'meleng o sireletsang, Ho bonolo ho lahleheloa ke matla ka ho a fetisetsa khubung ea athomo ea haedrojene, ho liehisa li-neutron tse potlakileng ho li-neutron tse liehang le li-neutron tse chesang. Ha 'mele o sireletsang o na le haedrojene e ngata, phello ea ho laola e tla ba matla le ho feta. Har'a litaba tsa haedrojene tsa thepa ea tšireletso ea neutron e sebelisoang hangata, litaba tsa haedrojene tsa polyethylene li phahame ka ho fetisisa, ho fihlela ho liathomo tse 7.92x IO22 /cm3 khase. Ka hona, polyethylene ke mohlokomeli ea molemo ka ho fetisisa oa tšireletso ea li-neutron tse potlakileng. Ka mora hore di-neutron tse potlakileng di fokotsehe ho ba di-neutron tse futhumetseng, thepa e sireletsang e nang le karolo e kgolo ya ho monya di-neutron tse futhumetseng ntle le mahlaseli a Y a matla a mangata e a hlokahala ho monya di-neutron tse futhumetseng, e le ho fihlella morero wa ho sireletsa di-neutron tse potlakileng ka botlalo. Ka lebaka la karolo e phahameng ya ho monya di-neutron tse chesang ya (3840 lL)X10_24cm2[3], mme bongata ba kiB boron ya tlhaho ke 18.98% [3], e leng ntho e bonolo ho e fumana, thepa e nang le boron e monya hantle bakeng sa ho sireletsa di-neutron tse futhumetseng.
Tšireletso ea mahlaseli a neutron litsing tsa matla a nyutlelie, li-accelerator tsa matla a mahareng (a phahameng), li-reactor tsa athomo, likepe tse tsamaeang ka tlas'a metsi tsa nyutlelie, li-accelerator tsa bongaka, lisebelisoa tsa phekolo ea neutron le libakeng tse ling.
