Abstract
Studies of the distribution of radiation about an x-ray tube are not new. Kaye (1) wrote about it in 1909. Coolidge and Kearsley (2) reported on it in 1922, and Bouwers (3) discussed it in 1928. More recently its significance and practical application have been reported by Ginsberg and Landauer (4). The subject has an important application in superficial therapy, where common practice calls for the use of large fields at a short focal skin distance. The distribution problem is especially important because the use of shock-proof tubes and equipment has made it more difficult to change from one type of tube to another. With non-shock-proof tubes it was a simple matter to remove the diagnostic tube from the lead glass bowl and substitute the therapy tube. A study of distribution and field coverage may have a useful application in the planning of protection and the design of equipment, especially in fluoroscopy. Also, to a lesser degree, it may be of value in diagnostic applications, although the distances us...
