Exceptional Accuracy. Developed at a cost of $5,000,000, it uses conventional X-ray equipment to photograph the breast. The difference is in the developing. Instead of X-ray film, the xero-radiograph uses a selenium plate that has been specially treated to make it sensitive to X rays. Once exposed, the plate is inserted into a processor similar to an office copier, where it is "developed" electronically. The result is an exceptionally accurate Xerox "picture" of the breast, its internal tissues and any cancer that might be present...
...dealt that faith a shattering blow. In a survey of 969 of the country's 23,000 water-supply systems, HEW's Bureau of Water Hygiene found that some 900,000 persons in the tested areas were consuming water dangerously contaminated by such poisons as arsenic, lead, selenium and fecal bacteria. The water supply of another 2,000,000, though safe to drink, was held to be unacceptable in taste, odor or color. Since the bureau's survey sites were chosen as "reasonably representative," its report, projected to the entire population, could mean that millions of Americans...
...that needs no chemicals, can duplicate anything from grease pencil to ballpoint pen, though it is more successful in copying type than photographs. The 914 makes copies by projecting the image of the original document or object onto an electrostatically charged drum coated with a sensitive element called metallic selenium. The machine automatically sprinkles the drum with a black powder that adheres to the dark portions of the image; the drum then rolls the powder onto the paper, which is also electrostatically charged. A quick blast of heat fixes the powder permanently to the paper...
...successive year, production hit a new peak with nickel deliveries of 290 million Ibs., while the company also delivered 263 million Ibs. of copper (worth $100 million), 1.637,000 Ibs. of cobalt (worth $4 million), 445,000 oz. of platinum (worth $20 million), plus smaller amounts of gold, silver, selenium and tellurium...
...growing, progressing economy, solving one shortage, will produce others in the process. By the time the selenium shortage is whipped, there may well be a scarcity of some new ium, not yet discovered...
