Abstract

See full text

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.
