Tumor cure studies on the rat sarcoma BA1112 using continuous low-dose-rate radiation.

Abstract
Delivery of continuous low-dose-rate radiation at a constant rate using an afterloading plastic helmet system can achieve the local cure of the BA1112 rat sarcoma. Complete dose response curves for local tumor cure were obtained at 170 rad (1.7 Gy [gray]) and 130 rad (1.3 Gy) per hour. The results are consistent with the known radiobiological properties of the BA1112 tumor. [Implications with respect to the use of this technique in humans are presented.].
