A study of the diagrams will readilyshow the superiority of interstitial radia-tion. The figures given for bare tube?consider only gamma radiation and donot take in the tremendous local effectsof beta rays. The number of pointsources are far below those used inactual practice and hence indicate alower dosage than is actually the making the comparison with externalradiation we must remember that thesedoses may be directed from two, threeor four angles at the tumor. Even atthat, the interstitial dose of gamma ra^salone is superior to the multiple ex-ternal cross-fire. The most marked ad-vantage of interstitial over externalradiation, of course, is in the smallermass at greater depth. i. Fiji, —.Same ca.^e as Fig. 14.
