Last week Radio Corp. of America demonstrated a sub-thimble-size radioactive battery that is somewhat more efficient. A film of Strontium 90 is spread on a wafer of silicon. When its beta particles shoot into the silicon, each of them releases 200,000 fresh electrons, which are collected as an electric current by a spot of silicon-antimony alloy...
...less dramatic (and usually nonfatal) forms of cancer. Example: blotting paper soaks up a solution containing phosphorus-32; the paper can then be cut to the exact shape of a skin cancer and held in place with adhesive tape. In a few days the cancer is arrested. Strontium-go, on the end of a probe, has been found to be even better than phosphorus-32 for treating malignant growths...
...sometimes destroys the crystalline structure of luminescent pigments, but one way that they can be dispersed, crudely ground, through oil or varnish to form paints is with the help of wetting agents (TIME, Jan. 5). Many of the phosphorescent pigments now manufactured in the U.S. are sulfides, chiefly of strontium, zinc, barium, calcium, cadmium, etc.; and a large group have formulas that are military secrets. The fluorescent pigments are chiefly beryllium and zinc silicates, cadmium borates, calcium and magnesium tungstates, and organic dyes...
