“…Bikini (11°35'N, 165°23'E), Enewetak (11°30'N, 162°15'E), and Mururoa Atolls (21°50'S, 138°50'W) ( Figure 1); produced hot spots of plutonium-contaminated areas in the marine environment. High 239,240 Pu concentrations in lagoon waters (more than 1 Bq m -3 in Bikini in 1982, 0.54 Bq m -3 in Enewetak in 1994, [111][112][113] and more than 0.1 Bq m -3 in Mururoa in 1991 [114][115][116] ) were observed, although no information is available on the effects on the outflow of local 239,240 Pu contaminated waters to the open ocean. The 239,240 Pu concentrations for the Mururoa lagoon waters decreased, with an apparent HRT of nine years.…”

Marine environments have been extensively contaminated by plutonium as a result of global fallout due to atmospheric nuclear-weapons testing. Knowledge of the levels and behavior of plutonium in marine environments is necessary to assess the radiological and ecological effects of plutonium. Such analytical techniques as radiochemical analysis, α-spectrometry, and mass spectrometry have been developed to analyze the plutonium in seawater over the past five decades. Because of complex chemical properties (e.g. high reactivity to particles), plutonium in the ocean exhibits more complicated behavior than other long-lived anthropogenic radionuclides, such as 137 Cs. In the present study, I reviewed the research history of plutonium in the ocean, including spatial and temporal changes of plutonium levels and distributions, and its oceanographic behavior.

“…The nuclear weapons testing sites in the Marshall Islands were monitored extensively by the US (e.g., Noshkin and Wong, 1980;Noshkin et al, 1983;Robison and Noshkin, 1999), and the impact of the tests carried out in French Polynesia were assessed by France and IAEA (e.g. Bourlat et al, 1991Bourlat et al, , 1996IAEA, 1998;Povinec et al, 1999).…”
