[Protection from X-ray radiation in the surgical room (author's transl)].
Constructional radiation protection of X-ray examination rooms is perfectly settled by DIN 6812. The present study was intended to ascertain safe handling of X-rays in the surgical room. The measuring technique with LiF-dosimeters is described, and its results concerning the load to surgical personnel are communicated. Though, with frequent operations, the monthly turn-on time does not exceed thirty hours according to DIN 6811, the maximum permissible individual dose, nevertheless, will be exceeded. A practical representation of radiation load as a function of the turn-on time will facilitate to surgical personnel the estimation of dose. Then, spatial isodoses are shown by means of which the necessary protection equivalent of the building can be calculated. Even the minimum demand for a limitation of the controlled area to the surgical room does require lead-equivalent protection if the surgical room is small.
