Title: The effect of temperature and relative humidity during drying on the covering power of processed x-ray films
Author: Lauffer, John M.
Abstract: With the constantly decreasing silver reserves and correspondingly higher costs, film manufacturers are continually searching for methods to reduce the amount of silver that is used. By using closely controlled conditions of temperature and saturated salt solutions to provide control of relative humidity during drying of processed x-ray film, it was found that the covering power may be as low as 70$ of its maximum value depending on the conditions used for drying the film. The highest values for covering power existed when the film was dried at low temperatures and high relative humidities or high temperatures and low relative humidities. The lowest values existed when both the temperature and relative humidity conditions together were either high or low. These results are promising in that high temperatures and low relative humidities can yield maximum covering power values while also providing the fastest possible rate of drying.
