...probably the seat of basic anxiety) to the frontal lobes of the cortex (where anxiety and pain are felt intellectually). Los Angeles' Dr. Tracy J. Putnam has devised a way of driving two hollow needles precisely into the chosen nerve bundles. These are then destroyed by seeds of radon (a radioactive gas) dropped down the needles...
Some weeks ago Dr. Otto Hahn of Berlin's Kaiser Wilhelm Institute donned his work clothes, walked into his laboratory to perform a physical experiment. With a stream of neutrons (obtainable by subjecting a pinch of beryllium to the emanations of the radioactive gas radon) he bombarded a bit of uranium. While the routine little experiment proceeded all was peace and quiet in the laboratory. There was no crash of thunder, no flash of cataclysmic lightning...
...powerful wave mathematics developed by Germany's Erwin Schrodinger, Drs. George Braxton Pegram, John R. Dunning and Isidor Isaac Rabi had to lead their particles like circus animals through a complex series of hoops & hurdles. Beryllium powder was placed in a glass tube containing the radioactive gas radon. Alpha particles from the radon knocked neutrons out of the beryllium. First hurdle was a metal ring which deflected part of the neutron beam toward a cylindrical detection chamber less than an inch across, a half-inch deep. The chamber's door was guarded by a paraffin screen from which...
...atomic disintegration, uranium (238.2) goes to ionium (230) to radium (226) to radon (222) to polonium (210) to lead...
...insulation, a greater concentration of gamma rays than hitherto could be safely used, may be applied without harmful or painful effect. The treatment consists of irradiation applied externally. After a time an operation is undertaken to remove some of the cancerous tissue, and little sealed gold tubes containing radon (the gas given off by radium) are inserted in the affected tissue. The radon gradually loses its potency, but meantime it is said to do its work...
