4. Radioactive water cannot be compared to raw petroleum, which is massive, tends to stick together,

and cannot mix with water. Most of the oil sinks to the bottom or floats onshore. As the article explains, the radioactive water very rapidly diffuses and is diluted by ocean water, from which it is virtually indistinguishable in behavior. Currents carry it away and rapidly dilute it to infinitesimal concentrations. Considering the radioactivity level is already vanishingly small, it becomes harmless in an ocean the size of the Pacific. No deceit here, just good science.
