Radionuclide biological half-life values for terrestrial and aquatic wildlife

Radionuclide biological half-life values for terrestrial and aquatic wildlife.

The equilibrium concentration ratio is typically the parameter used to estimate organism activity concentrations within wildlife dose assessment tools. Whilst this is assumed to be fit for purpose, there are scenarios such as accidental or irregular, fluctuating, releases from licensed facilities when this might not be the case. In such circumstances, the concentration ratio approach may under-...

(recommended) Half-life Values for Two Neutrino Double Beta Decay

All existing ”positive” results on two neutrino double beta decay in different nuclei were analyzed. Using procedure recommended by Particle Data Group weighted average values for half-lives of Ca, Ge, Se, Zr, Mo, Mo Ru (0+1 ), Cd, Nd and U were obtained. Existing geochemical data were analyzed and recommended values for half-lives of Te and Te are proposed. We recommend to use these results as...

Brucellosis in terrestrial wildlife.

The epidemiological link between brucellosis in wildlife and brucellosis in livestock and people is widely recognised. When studying brucellosis in wildlife, three questions arise: (i) Is this the result of a spillover from livestock or a sustainable infection in one or more host species of wildlife? (ii) Does wildlife brucellosis represent a reservoir of Brucella strains for livestock? (iii) I...

Contaminants and Health of Aquatic Wildlife

Evaluating summarised radionuclide concentration ratio datasets for wildlife.

Concentration ratios (CR(wo-media)) are used in most radioecological models to predict whole-body radionuclide activity concentrations in wildlife from those in environmental media. This simplistic approach amalgamates the various factors influencing transfer within a single generic value and, as a result, comparisons of model predictions with site-specific measurements can vary by orders of ma...
