D. Rationale

Describes a method for testing the adequacy of the darkroom safelight conditions, and the freedom from extraneous actinic light. Coverage includes terminology, frequency of testing, and calculation of safe handling time.

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 IEC1223-1.
