...X Rays for the Bonk Book. What keeps many clubs going is the yearly assessment to cover the losses. Others, like Chicago's Tarn O'Shanter, which has opened its clubhouse to 320 weddings so far this year, scout around for parties, conventions and tournaments, anything to make a dollar. Even some of the oldest clubs X-ray a prospective member's bank account first, his social position second. Says a member of the very exclusive Denver Country Club: "It is true that some of our nice members are the biggest stinkers in town. But heavens...
...until the debris could be gathered on the ground. Eventually, the scientists agreed on the right to use both methods. Debris is no help in measuring fallout caused by explosions in space. ¶ Electromagnetic radiation. Control posts, equipped with photocells and low-frequency radio receivers could pick up the X rays and ultraviolet rays that turn into light and radio waves after an explosion. They could even pick up the light pulses resulting from a blast in space. ¶ The seismic method, which with astonishing accuracy has already detected the size and location of underground explosions thousands of miles away...
...sources of the radioactivity that batters man, fallout from nuclear weapons testing is the least. At current levels, it is less than 5% of radiation from natural sources. But this is small comfort: the total of all radiation, largely from rocks, body chemicals, cosmic rays and X rays, may already be at a dangerous level. So warned a 15-country United Nations scientific committee last week, after studying world radiation for 2½ years. Shunning politics, the experts voted against urging a ban on nuclear tests. As top scientists, they voiced a sobering opinion: "Even the smallest amounts of radiation...
...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...
...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...
