...X-ray tube which can shoot more concentrated radiation through twelve inches of steel than could all past commercial tubes combined plus all the radium ever mined, was announced last week at the Radiological Society of North America. It is the first commercial tube to operate at two million volts...
...X-ray tube a stream of electrons from the cathode crashes into the target, impelled by the electrical voltage. Their speed goes up with the voltage-and the higher their speed, the more penetrating are the X rays produced when they collide with the metallic target. Low-voltage or "soft" X rays are sufficient to reveal cavities in teeth or the bones of the hand, because bone absorbs them and thus throws a "shadow" on the photograph. But to reveal gas bubbles or minute flaws in steel armor plate, very "hard" rays are needed, hence a very high voltage...
There is another reason for this X-ray tube's phenomenal performance: it uses a "magnetic lens," similar to that in the electron microscope (TIME, Dec. 14, 1942), to focus the electron beam in the tube on a bull's-eye only .01 inch in diameter, instead of the usual quarter-inch focal spot. Thus the X rays emerge in a sharp beam and produce well-defined shadows even after passage through thick steel...
...X-Ray plates taken of Correll's injured foot show that he will be able to rejoin the team in a couple of days. Together with Foley and Matt Dick, Correll will supply the extra punch needed for the races with Tufts and M.I.T. on September 30 and October...
...will send many more X-ray units into the field. Then he will turn over his pictures (and 85% of his $10,000,000 fund) to state health officers, who will carry on with treatment and control. Chief battleground will be the 92 biggest U.S. cities, whose T.B. death rate is a third higher than that of rural areas. Dr. Hilleboe's staff has recently discovered an amazing variation in T.B. incidence: San Antonio, the worst-rated city, has had ten times as many T.B. deaths (151 per 100,000) as Grand Rapids, which made the best showing.
