3 terminology and units of measurement

3.1 Exposure time exposuretime Also known as irradiation time, referring to the duration of the irradiation method prescribed measured X-ray machine, the radiation dose rate is usually Exceeds a predetermined level of the time. NOTE. The exposure time is usually based on load time measurements obtained. Loading time is measured by the method specified anode input power Rate applied to the X-ray tube time. Usually refers to the first X-ray tube voltage rises to a peak of 75% until the final descent to the phase Stop time interval of equal value. 3.2 Non-intrusive measurement of non-invasivemeasurement Analysis of the emitted radiation X-ray tube voltage is measured by. 3.3 The maximum peak voltage maximumpeakvoltage The maximum value of the X-ray tube voltage within a specified time interval, the amount of volts (V). 3.4 the average peak voltage meanpeakvoltage Within a predetermined time interval the average of all X-ray tube voltage spikes, the amount of volts (V). 3.5 Radiation detection limit X-ray detector can accurately respond to minimum air kerma rate in units of cGy/min.
