ERA (Energy Research Country of Origin: United States Country of Publication: United States Abstract: A large volume water sampler using manganese dioxide impregnated cartridges for the in situ separation of plutonium in sea water and ground water was studied. Plutonium concentrations obtained by this technique are compared with a radiochemical coprecipitation method. Consistent results were obtained between the two methods for water samples from the Pacific Ocean and Enewetak lagoon. Different results were noted from samples collected in the Enewetak reef and ground water stations. Using this preconcentration technique and the coprecipitation method it was shown that the physical-chemical characteristics of Pu in Enewetak reef and ground water are different from the lagoon and open ocean.; Major Descriptors: *ENIWETOK -- RADIATION MONITORING; *GROUND WATER -CHEMICAL COMPOSITION; *PLUTONIUM -- ENVIRONMENTAL TRANSPORT; *PLUTONIUM -- SEPARATION PROCESSES; *SEAWATER -- CHEMICAL COMPOSITION Descriptors: COASTAL WATERS; FRESH WATER; PACIFIC OCEAN Broader Terms: ACTINIDES; ELEMENTS; HYDROGEN COMPOUNDS; ISLANDS; MARSHALL ISLANDS; MASS TRANSFER; METALS; MONITORING; OXYGEN COMPOUNDS; SEAS; SURFACE WATERS; TRANSURANIUM ELEMENTS; WATER Subject Categories: 520301* Materials Monitoring & -- Environment, Aquatic -- Radioactive Transport -- Water -- 400100 -- Analytical & Separations Chemistry INIS Subject Categories: B32* -- Water Bll -- Chemical & Isotopic Analysis 10/5/957 00366652 (Item 657 from file: (1987) 103) AIX-08-344134; NTS-78-058656; EDB-78-061055 Title: Measurement of radioactivity Author(s): Yamagata, N.

Country of Origin: Japan Country of Publication: Japan Abstract: The measurement of environmental radioactivity in Japan started from the time of the nuclear test at Bikini in 1954, and Science and Technology Agency has established ’’Measuring Procedure of Radioactivity’’ in 1957. This is total beta radiation measurement, and now the revised draught including nine points to be revised has been JOGO I Publication Date: made. Since then, analyzing procedures were established for radioactive strontium, cesium-137, radioactive iodine, and radioactive cobalt, with
