[Dosimetry of the bladder and the rectum: comparison between the measured and calculated dose (author's transl)]

The authors examine 62 cases of curietherapy in the deep vagina on 21 cases of utero-vaginal applications and make a comparison between two dosimetric methods used to measure the dose to the rectum and to the bladder: the direct measure by the Siemens Gammameter dosimeter and the Chassagne-Horiot method. Very large differences were found between the doses evaluated by the two methods. The values with the direct measure were often found to be higher than the calculated ones. When the measurements were done by different doctors, the result was almost the same.
