![]() ![]() It is common practise in high-volume x-ray film processing departments to employ radiographic dark room entrances. Dark Room Entrance-Įntrances (doors) made to let workers enter x-ray processing dark rooms without letting light into the room or otherwise interfering with the film processing A two-door system with a space in between, rotating doors, or plastic doors that let one look into the dark room while still shielding the film from light are some examples of these entrances. It is crucial that the processing solutions be maintained and utilised properly, and that the dark room is built appropriately. All surfaces in the space should be painted a bright colour to decrease the amount of safe lighting needed and to make it easier to see light leakage. This surface need to be made of a sturdy, anti-static substance that is also simple to maintain. Although certain conditions must govern where a dark room is located, the following considerations might be kept in mind.įor the purpose of loading and unloading cassettes, the dark room area must have a work surface that is at least 1.3 metres long. Work Area-Ī permanent dark chamber should be designated, ideally with a floor space of at least 8 by 6 feet (2.6 X 2 m). ![]() If there is a darkroom technician, a pass-box from the radiography room to the darkroom will boost throughput and allow for the storage of loaded cassettes. The radiography room and the darkroom should be next to each other, with a direct passage leading from the radiography room to the darkroom’s door. In order to give the pulp chamber a black or radiolucent outline, more silver will precipitate and activate silver bromide crystals.The X-ray film is a fragile product that is susceptible to a variety of factors, including pressure, different gases and fumes, heat, moisture, and even age, which produces a gradual change in the film known as fogging. More X-rays will penetrate a region of lower density, like the pulp, hence more X-rays will hit that section of the film. The developer may be distinguished from the fixer by its vinegary odour when fresh and acid taste (alkali), as well as by its soapy texture. Most darkrooms will have the developer in the left tank, the water bath in the middle, and the fixing solution in the right tank as you face the tank. Accurate thermometer and interval timer.Washing Tank & Hot and cold running water.Both safe-light and white-light illumination.The walls of a light-tight darkroom should be painted a light pastel hue to reflect the room’s lights, not black. The X-ray films may get sensitised (fogged) by heat alone when the processing room’s temperature rises over 90° F.Įither the X-ray facility or the reading area should be as near as feasible to it. Air conditioning is a need if humidity is a concern, especially in some regions of the nation. The absence of light does not require human processing. The equipment should be placed in the room to speed up work flow and be within arm’s reach, and the space should be big enough to prevent congested circumstances for efficiency’s sake. Every piece of equipment needs to be in its proper position since processing operations are performed in almost complete darkness. ![]() The darkroom must be set up in such a way that processing film is quick, accurate, and consistent. The use of a dark room allows for the efficient and safe handling of films without the risk of accidentally exposing them to light or X-rays, which might cause film fog. ![]()
