All living beings based on carbon incorporate radioactive carbon-14 from nitrogen in the air that has been atom-smashed by cosmic rays. So, we are already radioactive, but at a trivial level. (Kind of fun to get a civil defense Geiger counter and test it on people at a party.) The dilution of seawater is truly staggering. Just because we can measure concentrations at parts per billion does not mean the concentration levels are any kind of threat. ..."Theory 'holds no water'..." Pretty sly. We probably have other things to worry about---like being killed by a direct meteor hit. I think this once happened to a guy sitting in his easy chair. Something the size of a toaster crashed through his roof and nailed him.
