Radium may be used in treating skin cancer in the form of a pack or plaque or in the form of needles applied interstitially. The use of the packs (or plaques) has no advantage except in rare instances and will not be discussed. It is our opinion that radium used for malignant cutaneous disease serves best when used in needles applied into the lesion.

We have used two interstitial techniques with needles for a number of years, namely, (1) a short-time highintensity method and (2) a long-time low-intensity method. The first has been described in a previous article1 and will be discussed only briefly here. The shorttime high-intensity technique (fig. 1) refers to the use of needles containing 10 mg. of radium, 19 mm. in length, with a wall filtration of 0.3 mm. of platinum. Their active length is 12 mm. These are inserted at the base of a
