New techniques in radium and radon therapy

Abstract

New methods for the application of both radium and radon to the treatment of malignant disease are described. The basis of the radium technique consists in the preparation and use of a number of small independent radium cells which can be inserted as required into hollow sheath needles of appropriate length. Further, the use of external stabilizer attachments for implants in the achievement and maintenance of planned distributions is discussed. The radon technique introduced concerns the use of seed-chains. By thus stringing together seeds in chain form, a valuable compromise between rigid needles and independent loose seeds is obtained, and the resulting applications are described.
