LÆKNABLAÐIÐ 213 In general, man is so well adapted to liis habitats, varied as they may be, that only when he drastically alters his radiation environment or ventures as do the astronauts into outer space does he have a chance to encounter serious problems related to radiation. One of the earliest recognized of industrial health problems was the chronic sickness in the miners at Schneeherg and Joachimsthal where, for many eenturies, many of the miners had died with illness involving the lungs. Through the Work of Koelsch,3 Sikl4 and otliers in Czechoslovakia this was recognized to be lung cancer, caused by inhalation in the air of tlie mines of excessive concentrations of radon, a radioactive gas derived from radium present in the rock. More recently the researches of Rutherford, Rohr, Lawrence. Strassmann, Fermi and their colleagues have placed limitless amounts of radioactive material at man’s command through atomic fission. The laborious efforts ol' 50 years had produced ahout two kilos of radium, and many scientific pioneers died as Fig. 1. Radiation dermatitis and fatal epidermoid carcinoma of the skin in a radiologist whose hand had received repeated exposure to X-rays aggregating several thousand R.
