[Radiogenic disorder in sense of smell (author's transl)]

The influence of radiotherapy on the sense of smell was investigated in 24 patient (age 28-80 years) with Elsberg's method. Out of 19 patients, who were measured 1-15 years after radiotherapy, the thresholds exceeded the normal range in no case, i.e. no permanent disturbance of smell after radiotherapy. In 5 patients, tested before, during and after irradiation, the thresholds rised continuously to the upper margin of the normal limit between 1,000 and 6,000 rads and, after the end of therapy returned to initial levels within 6-8 weeks.
