Abstract
STUDIES of the induced conductivity in insulators due to X-rays1 are difficult owing to the extremely low values to be measured, and hitherto have been made primarily with condenser chambers2. These allow only the after-effect of the radiation to be determined. If measurements of conductivity during exposure are to be made, the apparatus must admit no air gap at any point between the insulator under test and the electrometer, and in addition the volume of insulator irradiated must be as large as possible, so as to give sufficient current for measurement.
