“…A good accordance was observed among the measuring results and the reference values, confirmed by standard accuracy and precision tests used in IAEA proficiency tests (Shakhashiro et al, 2012;Osvath et al, 2016). Besides, the Canberra ISOCS/LabSOCS, used for gamma spectrometry analyses allows efficiency calibration for a wide range of both measuring geometries (Bronson, 2003) and sample materials including marine biota (Yang et al, 2015).…”

“…In this context, Praveen Pole et al (2017) calculated the total dose rate of 210 Po in several macroalgae species located close to nuclear installations on the southeast coast of India, obtaining values a few orders of magnitude lower than the limits proposed for marine biota (UNSCEAR, 2008). Also, in the Gulf area and the Qingdao coast of China, the radiological hazard index values for the marine biota samples in a study on 137 Cs, 40 K, 226 Ra, 228 Ra and 238 U reported by Al-Qaradawi et al (2015) and Yang et al (2015) were below the levels recommended by the IAEA (1992 and 2014), and there is no impact on human health for seafood consumers.…”

“…In terms of human health protection, contaminated organisms could pose a risk to health via the food chain (Jha 2004(Jha , 2008Aoun et al 2015;Yang et al 2015). 32 P uptake in humans may occur via dietary pathways, with dose being higher in the foetus and breastfed infants, than the adult (Oatway et al 2008).…”

The actinides comprise a group of 15 metals (with atomic numbers ranging from 89 to 103) that are all radioactive and occur as cations in natural surface waters. Only the first 10 actinides are covered in this study, as these are the most environmentally relevant, where the dominant oxidation states are as follow: actinium(III), thorium(IV), protactinium(V), uranium(VI), neptunium(V), plutonium(IV) and (V), americium(III), curium(III), berkelium(III), and californium(III). The physicochemical form, or speciation, of an actinide (e.g., free metal ion, or complexes with inorganic or organic ligands) in natural surface waters can be determined using a range of analytical techniques. However, such methods are seldom commercially available and rarely determine a complete distribution of all metal species. A complementary approach, which is more cost effective, time efficient, and predictive, is the application of geochemical speciation modeling, which calculates the percentage distribution of all actinide species based on known or postulated chemical reactions. The general consensus is that geochemical speciation models can provide useful results if applied correctly with an understanding of the differences between simulated and real systems. This is the first study to use an internally consistent equilibrium database within a geochemical model (WHAM) to calculate the speciation of the first 10 actinides across fresh, estuarine, and marine waters that incorporates natural dissolved organic matter (DOM) (i.e., fulvic acid). The speciation of a metal (actinide) largely governs its uptake and/or toxicity (bioavailability) in aquatic organisms. The general consensus is that bioavailability is best predicted by the concentration of the free metal ion (M z+ ) and that metals complexed with most inorganic ligands (e.g., carbonate or sulfate) or natural DOM, typically have low bioavailability. There is also evidence to suggest that colloidal thorium is bioavailable to freshwater organisms. The study correlates observed actinide speciation with bioavailability (where available) or utilizes predicted actinide speciation to determine the likely magnitude of bioavailability, as applied to aquatic organisms. This study also addresses the likely effects of global ocean acidification and increased natural DOM concentrations in fresh surface waters on actinide speciation and bioavailability.
