added bagge scanning - reference to fluoroscope
During the 1930s, 1940s and 1950s, many shoe stores used an X-ray machine to demonstrate how well a shoe fit the feet of the customer. By 1960 the practice had been discontinued in the United States because of safety concerns. The machines were still in use in Canada and Great Britain in the 1970s. <ref>http://www.orau.org/ptp/collection/shoefittingfluor/shoe.htm</ref>

X-rays are also used by a [[fluoroscope]] for examining baggage at airports, bomb squads, or for medical examinations where the Doctor requires real-time displays.
