galela:
1. Umthombo wovavanyo lomgangatho we-neutron we-252Cf kunye nomthombo oqinileyo we-neutron we-12000 / s (1 ± 20%) ubekwe kwindawo yesalathisi se-detector.
2. Ireyithi yokubala ye-neutron iyakuhlangabezana nemfuno yereyithi yokubala> 100 (1 ± 20%) / s.
Ukufumanisa ukusebenza kakuhle kwenkqubo yokubeka iliso yephakheji ye-B-row

Ixabiso leMisalarm
Kwimeko-bume ezinzileyo:
Sebenzisa i-sensor yendawo, amaxesha angama-10000, inqanaba le-alarm lobuxoki 1
Ngaphandle kokusebenzisa i-sensor ehleliyo, ireyithi ye-alamu yobuxoki kunye nezinga lokungachongwa lisetyenziswa kanye ngaphakathi kwe-12h
γ Impendulo kwimitha
Thatha amaxesha angama-50, i-alarm ngamaxesha angama-49
Ukucaphuka
Ngaphezulu kwe-100 v S / h, i-alam yemitha ephezulu iyakhutshwa kwaye isuswe ngaphakathi kwe-1min emva kokuba umthombo ushiye
I-alam ye-neutron eyenziwe ngemitha
Akukho alamu ye-neutron ivuswa xa iqondo lethamo le-γ-ray lifikelela kwi-100 Sv / h
Impembelelo yangasemva
Xa utshintsho lwangasemva lukhulu ngokwaneleyo ukwenza utshintsho olukhulu kwi-alam enokwenzeka, inkqubo yokubeka iliso iyakukhupha isilumkiso.
