Some calculations on radioactive fallout with especial reference to the secular variations in potential gradient at Eskdalemuir, Scotland

摘要: From a study of the variations in potential gradient at Eskdalemuir, Scotland, it is shown that radioactivity there has roughly doubled during past six years; other words, radioactive contamination equal activity to natural background occurred. Calculations indicate only some 2% this can be ascribed world-wide fall-out following thermonuclear explosions; remainder must have been generated locally. The obvious sources are atomic stations — notably Windscale Cumberland, and considered that, apart from accident October 1957, leaked material ever since first came into operation. resultant very considerable its relation danger levels discussed.
