X-ray radiation dose measuring device, has thin-film diode structure comprising e.g. film electrodes and photoactive semiconductor film layer

摘要

The device absorbs radiation and outputs a signal representing a measure of the dose, based on the absorption. The absorption structure consists of stacked thin film layers arranged on a film-like carrier (11) and including at least one thin-film diode structure for delivering the output signal. The diode structure may comprise two film electrodes (12,14) and a photoactive semiconductor film layer (13) between them. An independent claim is included for a radiation image pick-up apparatus.
