Abstract
A device for the sensitive detection of ultraviolet radiation in the range 1080–1260 A is described. This device is a Geiger-Müller counter in which the counts are initiated by the photoionization of iodine vapor used in the tube's filling. The range of response is determined by the ionization potential of iodine and the short wavelength cutoff of LiF, through which radiation enters the counter. Because of iodine vapor in the filling, the electrical characteristics of the tube are those of a halogen-quenched counter.Keywords
