Nuclear chain reactions, explosive or otherwise, produce four types of destructive radiation: 1) alpha rays (streams of high-speed helium nuclei;; 2) beta rays (beams of electrons); 3) gamma rays or X rays (high-frequency electromagnetic waves akin to light); 4) neutrons (subatomic particles with no electric charge...
...Alpha rays are stopped by clothing, beta rays by slightly thicker materials. But if a tiny speck which generates one of them gets into the body, it may radiate quietly until it has started a cancer or done some quicker damage...
Wind & Rain. To make sure it was not jumping at sensational conclusions, Eastman analyzed the strawboard. Chemists cut out bits of it which fogged X-ray film, and burned them. The ashes were strongly radioactive, shooting out beta rays (streams of electrons). They gave out no alpha rays (helium nuclei), thus proving that they were not the naturally radioactive elements: radium, uranium, or thorium. The only remaining possibility was that, the guilty particles came from the atomic bomb, were carried to the Middle West by the wind, and washed down by the rain. Six months after the explosion, they were...
