Comparative dosimetry studies were conducted on human pituitary irradiation by Co/sup 60/ gamma rays and the ultrahard radiation of a 17-Mev betatron. A wax-filled human cranium was used as a phantom and radiation was directed toward the pituitary region over a 200 deg sagittal arc (pendulum angle). To produce a local dose of 200 r required ~ 3 min with 2000 c Co/sup 60/ as compared with 3 to 5 min with the betatron. Dose gradient data showed that ~ 25% of the Co/sup 60/ radiation was dissipated in cranial and superficial structures compared with only 10% of the ultrahard radiation, so that the dose reaching the target zone was considerably greater with the latter irradiation technique. The use of ultrahard radiation in the treatment of pituitary tumors and hyperactivity, in preference to surgical and radioactivity-implantation methods, is discussed. The possible use of this method in treatment of Parkinson's disease is also considered. (H.H.D.)
