210Po and 239Pu, 240Pu in biological and water samples from the Bikini and Eniwetok atolls

MEASUREMENTS of the radioactivity in water and biological samples from Bikini and Eniwetok lagoons indicate that although the samples were collected from the most plutonium-polluted waters of the world, the values of the naturally produced radionuclide, polonium-210 were usually greater than the values of plutonium-239 and 240, which are produced by nuclear detonations by factors as great as 100.
