thela:
1. Umthombo wokuhlola ojwayelekile we-neutron we-252Cf onomthombo oqinile we-neutron ongu-12000 / s (1 ± 20%) ubekwe endaweni yephoyinti yereferensi yomtshina.
2. Izinga lokubala lenutroni lizohlangabezana nemfuneko yezinga lokubala> 100 (1 ± 20%) / s
Ukutholwa okuqinile kwesistimu yokuqapha iphakheji ye-B-row

Ngaphakathi kobubanzi bendawo yokuthola
Abahamba ngezinyawo ± 25% Iphekhi Yomugqa ± 25%
Isilinganiso se-Misalarm
Endaweni ezinzile:
Sebenzisa inzwa yesikhala, izikhathi eziyi-10000, izinga le-alamu elingamanga 1
Ngaphandle kokusebenzisa inzwa ehleziyo, izinga le-alamu elingamanga nezinga lokungakhonjwa kahle kusetshenziswa kanye phakathi kuka-12h
γ Ukusabela Ngemisebe
Thatha izikhathi ezingama-50, i-alamu izikhathi ezingama-49
Ukucasuka
Ngaphezulu kwe-100 v S / h, i-alamu ephezulu yemisebe ikhishwa futhi isuswe kungakapheli i-1min ngemuva kokushiya umthombo.
I-alamu ye-neutron eyenziwe ngemisebe
Ayikho i-alamu ye-neutron eqalwayo lapho izinga lomthamo we-γ-ray lifinyelela ku-100 Sv / h
Ithonya elingemuva
Uma ukuguqulwa kwengemuva kukhulu ngokwanele ukuthi kubangele ushintsho olukhulu emathubeni e-alamu, isistimu yokuqapha izokhipha isixwayiso.
