The traditional method of starting therapeutic radium dosages in ``mgeh'' (milligram element per hour) lacks accuracy in its clinical application. Especially in the therapy of cancer with massive doses, it is of utmost importance to have some knowledge of the amount of radiation which will reach the anatomical structures surrounding the lesion and to anticipate the intensity of reaction in that area.

By means of a special r-meter (``Gammameter,'' built by the Siemens-Reiniger-Werke, Germany), the author measured the r/hr. depth doses of certain quantities of radium, mounted in differently shaped applicators. He then recorded the measurements on graph paper and charted the isodose curves.

An introduction and brief explanations in German and English accompany the charts. Since the booklet is written by a gynecologist for gynecologists, it is of only limited practical value to the dermatologist.
