The new method of calculating the integral dose for circular or rectangular fields was introduced in accordance with its definition. The value obtained by this method was compared with that by graphic, Mayneord's, and Eto's methods. The dose was measured three-dimensionally by ionization chamber (Victereen, Radocon, and home-made extrapolation chamber) at a number of points 2 cm apart, in a paraffin phantom, and reliable isodose charts were obtained. The value of the integral dose by the new method was nearly equal to that of the graphic method with charts and was shown to be more real compared to that obtained by Mayneord's or other methods. A desirable feature of the method is that the integral dose is obtained without using the isodose chart in part of the main beam as well as outside of the main beam. (Abstr.
