The use of radioactive isotopes and Geiger counters in brain tumor operations has been developed by a group of four Boston scientists including Charles V. Robinson, research associate in Biophysics, and Arthur K. Solomon, assistant professor of Physical Chemistry, both of the Medical School, Massachusetts General Hospital reported yesterday.

Research on this project began in July, 1947, under Drs. Bertram Selver-stone and William H. Sweet of Massachusetts General Hospital.
