Summary[edit]

Description
English: Photo of experimenters taking an X-ray with an early Crookes tube apparatus, from the late 1800s. The Crookes x-ray tube is visible suspended at center. The upper man is examining the bones of his hand with a fluoroscope screen. The lower man is taking a radiograph of his hand with a photographic plate. The power source is an induction coil, seen at left, and the mechanism immediately to its right against the wall is a motor-operated 'break wheel' interrupter in the coil's primary circuit. The large flat disk on the table is a rheostat (adjustable resistor) power control to adjust the primary current to the coil. Several spare Crookes X-ray tubes are seen in a rack on the wall. The apparatus is described and diagrammed on p.88 of the source. No precautions against radiation exposure are taken; its hazards were not known at the time. The original image was half-tone. Alterations: removed frame.
