1 Scope and object

1.1 Scope

This technical report applies to darkrooms in X-ray facilities where any of the following unprocessed radiographic or photographic materials sensitive to light are handled:

• — all types of screen film;
• — non-screen film;
• — photographic film for indirect radiography, as used for recording:
  • • output images of x-ray image intensifiers;
  • • other radiological images after transfer;
• — photographic material for copying radiograms;
• — photographic material for making permanent images of information recorded by electronic means, and presented on display tubes; for example: using hard copy cameras, or printed by other electronic means, for example: laser; or used in diagnostic equipment, such as for general reconstructive tomography; digital imaging; ultrasound; magnetic resonance techniques; in nuclear medicine.

This technical report is a part of a series of Particular Publications (standards and technical reports) which will describe test methods for the constancy of properties of various subsystems of diagnostic x-ray equipment, as described in IEC 1223-1.
