Show How Much Radiation Is Felt Dangerous? Very often the question arises, how much radiation is too much radiation. Government and private pri-vate experts are attempting to determine the answer. The radiological health service of the Public Health Service is trying to calm unnecessary fears and panic and shed as much light as possible on a murky subject. Men have been exposed to radiation throughout the ages, so it is not new. Dr. Donald Chad-wick, Chad-wick, chief of the radiological division, puts it this way: "Mankind has always lived with radiation from cosmic rays originating in outer space and from natural radioactivity in the environment." Added to this in recent years has been the radiation which comes from more widespread use of medical and dental X-rays, fallout from nuclear weapons, and some aspects of nuclear energy en-ergy production-. Nuclear power, with adequate safeguards, may be the world's answer to dwindling supplies of coal and oil. It may be the source of needed power for more elec- tncity in nomes ana lactones. It may be used to excavate harbors, develop water sources, heat reservoirs and mine low-grade low-grade ore. Scientists have developed two different processes for removing strontium 90 from milk. As much as 98 per cent of the radioactive material can be removed in this way. It has not been decided which of the two processes will prove most practical for industry or how much this extra processing process-ing will add to the cost. This fallout comes to earth on pastures where cattle graze and thus enters into the, country's milk supply. As for growing vegetables, such as spinach and lettuce that happens to be in the fallout path, the deposit can be washed off like any foreign matter. On the grains, such as wheat, contamination contami-nation is eliminated in processing process-ing when the grain ends up as white flour. This would not be the case, however, with respect to bran, where the outer coat of the grain remains in the finished product. |
