Abstract

PURPOSE:To make the device possible to control the exposed dose and to prevent an excessive exposure over the allowable limit by constituting the device so that the X-ray exposing time is displayed digitally and a warning is outputted when the displayed value attained to a predetermined value. CONSTITUTION:An oscillator 1 for generating prescribed pulses and a counter 7 for counting the pulse during an X-ray exposure are provided, controlled with a switch 2 for fluoroscopy or photographing, and a counted value from the counter 7 is displayed on a displaying device 8 through a displaying device driving circuit 9. A setting device 12 for setting the exposure time for individuals corresponding to the allowable exposure limit is provided, the limit and a counted value are compared with a comparator 13, an output is generated to operate an alarm device 15 when the counted value exceeds the set value. Thus an X-ray exposure is controlled accurately with a low prised constitution, and the attainment to the allowable value is perceived immediately, and the operability is improved.
