"Even if we use the higher concentrations, the concentrations we measured in 2011, the doses to human consumers are very low, and lower than the naturally occurring radionuclides, " he said.
However, because it emits very low energy radiation and leaves the body relatively quickly, for a given amount of activity ingested, tritium is one of the least dangerous radionuclides.
These geomicrobiological changes can capture or release toxic metals and radionuclides attached to minerals making these interactions vital to our understanding of environmental contamination and also to exploit potential bioremediation techniques to treat contaminants.
