Abstract
In this paper we consider two types of gaseous detectors for radiography. The first one, the Multiwire Proportional Chamber, is used at present as a part of the digital radiographic system. It works in counting mode, has a quantum efficiency of 30% and a spatial resolution of 0.6 mm. Our new detector, the Multistrip Ionisation Chamber, is filled with Xe at 10 atm., has a quantum efficiency up to 70% and a spatial resolution of 0.4 mm. This method with integration of collected charge allows to avoid the problems of counting rate and gas ageing and considerably reduces the cost of electronics.
