Irradiation Event​

An irradiation event is the loading of X-Ray equipment​

caused by a single continuous actuation of the​

equipment's irradiation switch, from the start of the​

edge of the final pulse. Any automatic on-off switching​

of the irradiation source during the event is not treated​

as separate events, rather the event includes the time​

between start and stop of irradiation as triggered by the​

user. E.g., a pulsed fluoro X-Ray acquisition shall be​

treated as a single irradiation event.​
