Abstract
PURPOSE: To obtain a sufficiently stable plateau effect even when Q gas is used by forming a metal layer of gold or nickel on the radiation incidence window film.
CONSTITUTION: The metal layer 10 of gold or nickel is evaporated onto the surface, which will come in contact with a counting gas that flows in the container, of the thin film 9 made of organic compound such as polyethylene terephtalate or the like in order to obtain the radiation incidence window film 2. Since the thin metal layer 10 is evaporated onto the surface of the window film 2, the film 2 has conductivity and the metal layer provides a stable plateau characteristic even when Q gas is used for the counting gas. When the radiation incidence window film 2 is used by fixing itself to the upper part of the container as before, a sufficiently stable plateau characteristic can be obtained even when Q gas is used for the counting gas.
