PROPORTIONAL COUNTER
Document Type and Number:
WIPO Patent Application WO/2008/059966
Kind Code:
A1
Abstract:
Disclosed is a proportional counter wherein nitrogen and hydrogen are contained
in a gas (13) which is sealed in an envelope (12). By adding nitrogen, possibility
of polymerization of the additional gas by radiation disappears, and a higher
resolution is attained when compared with the cases where carbon dioxide is used
as an additional gas. By adding hydrogen, gas gain variations are suppressed.
