...unit that science uses to measure radiation exposure is the rem. It expresses a fixed amount of absorbed energy, corrected for the biological effects of different kinds of radiation. Radiation's vital targets: gonads and bone marrow. From natural sources, the average man is exposed to about one-tenth rem annually. In developed countries, he may also get almost as much extra each year from medical and dental X rays...
...significance of nuclear fallout. They found least long-range danger from that which swirls through the troposphere (the part of the atmosphere that goes seven to eleven miles up) for several months before falling. At most, its short-lived isotopes raise annual external marrow and gonad dosage by .0005 rem. But the higher stratosphere (beyond eleven miles) is a reservoir of long-lived isotopes that fall for many years. Chief dangers...
...result of bomb tests to date, caesium 137 dosage in Japan and the U.S. will rise by one hundredth of a rem per capita over the next 30 years. The strontium 90 rise in the next 70 years will vary in each country. For milk-drinking Americans, it will average an estimated .16 rem (or roughly the present dosage from X rays). For rice-eating Japanese, whose crops draw in more strontium because their soil lacks calcium, the per capita increase will be nearly one rem...
...nuclear-bomb fallout accounts for between 400 and 2,000 leukemia cases a year (total: 150,000), as compared to 15,000 from natural radiation. Science is not yet sure how much radiation is needed to produce leukemia. The U.S. National Academy of Sciences estimates the threshold as 40 rem. If this is true, and if all bomb tests stop this year, said the U.N. report, then the ultimate total of fallout leukemia cases would be between 25,000 and 150.-000. (But should the threshold be as much as 400 rem. probably no leukemia cases could be caused...
...Panama's Jose Antonio ("Chichi") Remón became national police chief in 1947, made and unmade five Presidents, won a free election himself in 1952, was chopped down, at 46, by machine gun bullets at Panama City's old Juan Franco race track in January...
