...been in the hands of science only a short time. Only in 1934 did Irene Curie* and her husband, Frédéric Joliot, first make ordinary elements such as iron and iodine radioactive so that they give off sub-atomic particles and gamma rays just as radium does. The invention of the cyclotron, Ernest Orlando Lawrence's great atom-smashing machine in California, simplified the manufacture of such elements so that they are now commonplace in physical laboratories. And in Copenhagen in 1935 O. Chiewitz and G. Hevesy first used such artificial radioactive elements as tracers...
...since then "the radioactive isotopes of 21 elements have already been employed . . , as tracers for metabolic studies." Their usefulness is that: 1) chemical and physiological properties of radioelements are identical with those of stable elements; 2) they can be used in tiny quantities which do not harm tissues as radium exposure sometimes injures human flesh; 3) wherever the radioelements go in organisms, they announce their presence by giving off detectable rays...
...either the radium or cyclotron bombardment of the diamonds, Dr. Berman explained, a short lived radioactive form of carbon is produced, together perhaps with some gas, like helium. The theory is that such gas molecules could become tightly lodged in the microscopic crevices of the diamond structure, and could impart the green color through a scattering of light rays...
...When the radium-green diamonds, are heated, it is conjectured, the gas molecules bounces from the crevices and the diamond becomes white again. In the cyclotron-green diamonds the heating supposedly simply rearranges the gas particles in such a way as to impart the yellow-brown color. No way has yet been found of dispersing or changing the yellow-brown effect, Dr. Berman said...
These rays are really bombardments of tiny electrical particles, which easily penetrate matter. There they dislodge electrons from atoms and molecules, making some positive, some negative in charge-i.e., ionized. Ionizing radiations damage living matter: many pioneer workers with radium were maimed and killed...
