Zokwiyitsa
Kupitilira 100 v S / h, alamu yowunikira kwambiri imatulutsidwa ndikuchotsedwa mkati mwa 1min pambuyo gwero lichoka.
Alamu ya neutron yopangidwa ndi ma radiation
Palibe alamu ya nyutroni yomwe imayambitsidwa pamene mlingo wa γ-ray ufika 100 Sv / h
Chikoka chakumbuyo
Pamene kusintha kwakumbuyo kuli kwakukulu kokwanira kupangitsa kusintha kwakukulu kwa alamu, makina owunikira adzapereka chenjezo lochenjeza.
