[A new type of radioactive wires and "hairpins" for the interstitial curietherapy of malignant tumors (author's transl)]. / Eine neue Art radioaktiver Drähte und "Hairpins" für die interstitielle Curietherapie von bösartigen Tumoren.

A new method has been developed for the production of radioactive wires and "hairpins" showing from their middle up to their ends a linear increase of specific activity. The advantages offered by these wires and "hairpins" have been introduced with good results in a series of new implantation methods for the interstitial curietherapy of malignant tumors.
