Fig. 7—Fission products in the Oct. 26, 1964, rain collected at Fayetteville, Ark. The concentrations in rain are expressed in terms of
10 atoms per liter of rain as of Oct. 16, 1964 (the date of the nuclear
explosion). The vertical bars indicate the magnitude of decay of the
longer lived nuclides since December 1962.
