...largest single category of fatalities. The number of deaths and disabilities caused by work-related illness is harder to gauge because the effects may not appear for years. Lamp-industry workers of the '40s are still dying from berylliosis, a lung disease brought on by exposure to beryllium, a lightweight metal used for coating fluorescent lighting tubes. Similarly, workers who inhale tiny, indestructible fibers of asbestos as they are blown into place for insulation can contract lung cancer more than two decades later. Dr. Irving J. Selikoff of Manhattan's Mount Sinai Hospital, an expert in asbestos-related...
...deeper into the lungs than it could on its own; without particles to carry it, the gas can be exhaled relatively easily from the upper respiratory tract. Other participates act as catalysts in the atmosphere, speeding the conversion of sulphur dioxide into more harmful sulphuric acid. Particles of arsenic, beryllium, cadmium, lead, chromium and possibly manganese, discharged into the atmosphere by a variety of man-made processes, may contribute to cancer and heart disease...
...sufficient neutrons are released and react with the core material to sustain violent nuclear reactions. In the implosion bomb shown in the sketch, shaped charges of high explosives (B) are simultaneously triggered by detonators (A), the force of the explosions being directed inward, rapidly compressing the plutonium around a beryllium neutron source (D). In less than a millionth of a second, the supercritical mass explodes...
...students to live on Putnam Ave, because his "impression of the neighborhood is that it is pretty bad." The Young Republicans show some inclination to elect a gorilla as their club's vice-president. The Atomic Energy Commission blames last summer's $1.5 million bubble-chamber explosion on faulty beryllium windows and says that only luck kept it from being worse...
...explosion was set off, it is now believed, when highly flammable liquid hydrogen broke through beryllium windows on the CEA bubble chamber, which was being filled for the first time. The CEA has decided since the explosion to abandon the apparatus and bubble chamber research...
