The Response of X-Ray Films to Indium-116 beta Radiation from Neutron-Activated Indium Foils

摘要

The characteristic curves, relative speeds, and image unsharpnesses have been determined for Kodak X-ray film types KK, AA, and M, and type F alone and in combination with six fluorescent intensifying screens to meet our needs in neutron radiography studies. The density ranges considered were 1.0 to 2.5 for the combination film and screens and 0.3 to 3.0 for the films alone, for exposure to diffuse beta radiation from 54-minute indium-116. The beta-ray characteristic curve shapes are in good agreement with curve shapes reported using 200-kv X rays, while the filmscreen combinations have curve shapes that differ. (Author)
