Popis: During the summer of 1962 the potential gradient was measured at Mercury, Nevada, as a function of height above ground level. At the earth's surface the value was +30 v/m; this rose steadily with altitude to reach a maximum of +110 v/m at a height of about 1200 m. The interpretation of these results suggests that the surface γ-ray activity for areas adjacent to atomic weapon test sites in Nevada is perhaps ten times the normal background.
