“…This change is attributed to the reduction in 210 Po discharges after 1993 due to the cessation of the use of phosphate ore in the plant. Rollo et al (1992) and McDonald et al (1992) collected marine biota from around the UK in 1987-1990 and measured their NORM concentrations. The results indicated a clearly enhanced level of NORM along the Cumbrian coast.…”

“…Surveys of concentrations of NORM in the coastal waters of the UK revealed (Rollo et al, 1992) that the chemical plant at Whitehaven in Cumbria, UK which manufactured phosphoric acid from imported phosphate ore was an important source of NORM radionuclides to the marine environment from 1954. Phosphogypsum has been discharged as liquid slurry by pipeline to Saltom Bay.…”

“…The higher values measured by Rollo et al (1992) are noted, however. The value of 3.5 Bq.kg −1 proposed by UNSCEAR 1 could apply to a mixture of large and small fishes, 1 The UNSCEAR reference value for fish products is 2 Bq.kg −1 fresh using a factor of 0.6 in order to take into account the 210 Po decay but not to crustaceans and shellfish.…”

-The data on 210 Pb and 210 Po activities in French foodstuffs acquired during the last 15 years are numerous enough to derive reference values which will be usable to assess the dose to the French population due to the intake of these two natural radionuclides. The means and ranges are close to those observed in various countries and are most often higher than the reference values proposed by UNSCEAR. Mussels and oysters exhibit the highest 210 Po activities of all kinds of foodstuffs, with a mean value of 27 Bq.kg −1 fresh weight , followed by crustaceans and small fish species (anchovies, mullets, sardines, etc.) with 210 Po activities in the order of 3 to 10 Bq.k −1 fresh weight; cephalopods and other fish species presenting activities around 1 to 3 Bq.kg −1 fresh, close to the UNSCEAR reference value. Below these highest 210 Po activities are those of 210 Po and 210 Pb in terrestrial kinds of foodstuffs, by decreasing order: meats (around 1 Bq.kg −1 fresh), cereals (0.4 Bq.kg −1 ), leafy vegetables (0.3 Bq.kg −1 ), other vegetables and fruits (0.1 Bq.kg −1 ), and milk (from 0.03 to 0.1 Bq.L −1 ).

“…However, Rollo, Camplin, Allington, and Young (1992) analyzed a range of invertebrates and fish from the marine environment of the United Kingdom. Mean concentrations of 234 U in shellfish ranged from 1.4-5.6 Bq/kg (wet weight), 235 U ranged from 0.027-0.19 Bq/kg, and 238 U ranged from 1.2-5.5 Bq/kg (Rollo et al, 1992). The concentrations at Amchitka were all well below these concentrations, but higher than those from the coast of Japan (0.20 Bq/kg 238 U, Ishikawa et al, 2004).…”

Concentrations of 13 radionuclides (137Cs, 129I, 60Co, 152Eu, 90Sr, 99Tc, 241Am, 238Pu, 239,249Pu, 234U, 235U, 236U, 238U) were examined in seven species of invertebrates from Amchitka and Kiska Islands, in the Aleutian Chain of Alaska, using gamma spectroscopy, inductively coupled plasma mass spectroscopy, and alpha spectroscopy. Amchitka Island was the site of three underground nuclear test (1965-1971), and we tested the null hypotheses that there were no differences in radionuclide concentrations between Amchitka and the reference site (Kiska) and there were no differences among species. The only radionuclides where composite samples were above the Minimum Detectable Activity (MDA) were 137Cs, 241Am, 239,249Pu, 234U, 235U, 236U, and 238U. Green sea urchin (Strongylocentrotus polyacanthus), giant chiton (Cryptochiton stelleri), plate limpets (Tectura scutum) and giant Pacific octopus (Enteroctopus dofleini) were only tested for 137Cs; octopus was the only species with detectable levels of 137Cs (0.262 +/- 0.029 Bq/kg, wet weight). Only rock jingle (Pododesmus macroschisma), blue mussel (Mytilus trossulus) and horse mussel (Modiolus modiolus) were analyzed for the actinides. There were no interspecific differences in 241Am and 239,240Pu, and almost no samples above the MDA for 238Pu and 236U. Horse mussels had significantly higher concentrations of 234U (0.844 +/- 0.804 Bq/kg) and 238U (0.730 +/- 0.646) than the other species (both isotopes are naturally occurring). There were no differences in actinide concentrations between Amchitka and Kiska. In general, radionuclides in invertebrates from Amchitka were similar to those from uncontaminated sites in the Northern Hemisphere, and below those from the contaminated Irish Sea. There is a clear research need for authors to report the concentrations of radionuclides by species, rather than simply as 'shellfish', for comparative purposes in determining geographical patterns, understanding possible effects, and for estimating risk to humans from consuming different biota.
