The cabinet was probably used for holding a radioactive material, that could be used as a source of radiation for radiography (X-Rays, though not necessarily using X ray radiation). Probably cheaper and more portable than an 'electronic' X Ray machine in the days of valve electronics. Owain |

Owain is correct. "Our operatory walls and cabinets are lead-lined to prevent any unnecessary x-ray exposure to patients and staff." http://www.elmtreedental.com/safety.html |

I would expect the cabinet to be used to STORE unexposed glass x-ray plates, to keep it from getting exposed to scattered rays from an old x-ray machine.(Old x-ray machines used coated glass plates as opposed to the x-ray film used now) The first dental x-ray was taken in 1896. Today radiology department walls are lead-lined to prevent scatter from leaving the area, and unexposed x-ray film is protected in a lead lined box or cabinet still. http://www.ada.org/public/topics/history/timeline_19cent.asp http://www.lateralscience.co.uk/xray/ ~crabcakes |
