A light meter has been designed and built for the purpose of measuring the light emitted from an intensifying screen during x-ray irradiation. The meter uses a photodiode detector with a minimal drift amplification system. The meter repeatability was better than 0.5% and was found to be linear. A significant x-ray induced signal was recorded during measurement which needed to be subtracted from readings to deduce the intensification screen light output. The energy response of four screen types was subsequently measured.
