AAAS, Apr. 7, 2011 — William Burnett, director of FSU’s Environmental Radioactivity Measurement Facility: There are other radionuclides that are likely in the waste stream [...] possibility of fuel material, containing U, Pu and other transuranics [...] This is actually an area that many scientists want more information about — what is actually contained in the releases?
Interview with Ken Buesseler, senior scientist at Woods Hole Oceanographic Institution, NPR (Wisconsin), Sept. 3, 2013: Q: What are you testing in the ocean? A: Several isotopes — cesium… tritium, strontium we’ve been looking for, small amounts of plutonium and other things.
Robin Brown, Canada’s Department of Fisheries and Oceans, Feb. 7, 2014: “Plutonium, of course, is terrible stuff, but the data I saw [on Fukushima] said it wasn’t released in very large volume. [When it hits seawater it] will end up in the sediment.”
It’s often claimed that plutonium ‘will end up in the sediment’ — What do the scientists who’ve studied this say (emphasis added)?
UNDERSTANDING GEOCHEMICAL PROCESSES CONTROLLING COLLOID-FACILITATED TRANSPORT OF PLUTONIUM, Oct. 30, 2013: Recent experimental data from Powell and others suggest that these simplified models cannot adequately predict Pu transport [...]
EFFECT OF NATURAL ORGANIC LIGANDS ON PLUTONIUM SORPTION… (pdf), Oct. 30, 2013: Clays [...] have previously been shown to strongly sorb [take up and hold] radionuclides, coupled with their ability to be transported as colloids, Pu, can lead to an increase in the environmental mobility of radionuclides.[...]
INVESTIGATIONS INTO THE FORMATION OF NEPTUNIUM(IV)-SILICA COLLOIDS (pdf), pg. 384, 2013: Due to the low solubility at neutral pH, tetravalent actinides are assumed to reveal immobile migration behaviour. Nevertheless, a high environmental mobility has been found, e.g. for Pu(IV) [Plutonium(IV) oxide] […]
SYNTHESIS AND CHARACTERIZATION STUDIES OF SONOLYTIC COLLOIDAL SPECIES OF PLUTONIUM (pdf), pg. 105, 2013: “hot particles” are of a great concern, because of their potential hazards [...] Their release is mostly due to nuclear accidents, i.e. at Chernobyl or Fukushima and military tests […] nano/micrometer-sized actinide particles containing colloids are of a particular interest, considering their potential to be transported in the hydrosphere and geosphere, and consequently being ultimately transferred in the biosphere. [...] In this work is highlighted for the first time the sonochemical synthesis of plutonium colloids from pure water dispersed plutonium oxide [...]
