[Gonadal load in radiotherapy of benign diseases. II. Infectious diseases and keloids].

The irradiation damages to the gonads caused by the radiotherapy of parotiditis and mastitis and of cheloids was determined partially under different irradiation methods. The measurements were effected with LiF dosimeters in the Alderson phantom with a tube tension of 250 kV for the inflammatory diseases and 55 kV for the cheloids. The gonad dose measured at the surface was within the range of hundreths of permille for the parotiditis, for the mastitis is was between tenths of permille and 2% depending on the therapy method. The gonad dose of the cheloid irradiations showed a clear relation to the distance between radiation source and gonads. The importance of radiological protection is emphasized.
