- Photographic film is generally very insensitive to direct x-ray exposure. Even
- film designed for x-ray exposure, such as that used in medical diagnostic
- radiology, has an x-ray sensitivity of less than 1%. For this reason, x rays
- are converted to visible (or near visible) light energy by the use of
- intensifying screens (similar to the principle you were using). Direct film
- exposure is used in certain situations where high resolution is needed, but at
- the cost of increased patient exposure.
