Abstract

The glass tips of treatment cones on most therapeutic x-ray machines used in dermatologic practice are made of ordinary glass that does not contain any filtering substance. Therefore, it would seem reasonable that scatter radiation from the field being treated would be transmitted through the glass and add to the total scatter in the treatment room.

Recently, we did some measurements which indicate that a significant reduction in scatter radiation in the treatment room can be achieved by wrapping the glass tips of cones in lead rubber or lead foil.

The illustrations (Figs. 1 and 2) show that a rubber band can be used to hold the rubber or foil wrapped about the glass tip. The wrapped material can be pushed up for viewing through the glass and pulled down, flush with the pattern surface, before starting treatment.

From Table 1, it can be seen that under the conditions indicated
