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.;

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
