CLINICAL MEDICINE

Detailed explanation-1: -It should be stored at temperatures between 50-70 degrees F. It must be stored away from heat, chemicals or radiation. All of these will adversely affect the film. Always use oldest film first because film deteriorates with age.

Detailed explanation-2: -Based on NARA 1571, the ideal temperature for storing modern, polyester black and white films is 65 degrees Fahrenheit. Black and white acetate-base film (generally pre-1970) should be kept at 35 degrees Fahrenheit.

Detailed explanation-3: -Keep all packages away from heat sources; store in a cool, dry place at a temperature between 50° and 75°F (10° to 24°C). Keep opened packages of film at a relative humidity between 30° and 50 percent. An inexpensive instrument called a sling psychometer can be used to measure relative humidity.

Detailed explanation-4: -Optimum temperature (20-22 oC) is required for developing. Usual developing time is 5 minutes at 29 oC, when done manually. In automatic film processors, these factors are taken care of by the processor and thus the image quality is more consistent.

Detailed explanation-5: -A temperature of 68 degree F (20 degree C) for 5 minutes is recommended for these reasons: a) The optimum quality of radiographs are attained at this temperature. The contrast and density of the film are most satisfactory and fog is kept to an acceptable low level.
