Abstract
Inspite of the many studies carried out and reported so far by many doctors on scattering X-rays observed in taking chest films, no anonimous conclusion about the scattering ratio of X-ray etc. have yet been obtained. Especially when the scattering ratio of X-rays is measured using the film-blackening method, the results differ according to the used photo-sensitive material. Using the most common materials at present, the author studied chest problems, namely the scattering X-rays in different tube voltages, Al. filters with different thickness, different F.P.D. and projected fields with different width. General consideration of these separately obtained experimental results was also added in this report.
