Small amounts of cesium-137 and cesium-134 were detected in 15 tuna caught near San Diego in August 2011, about four months after these chemicals were released into the water off Japan's east coast, scientists reported on Monday.
That is months earlier than wind and water currents brought debris from the plant to waters off Alaska and the U.S. Pacific Northwest.
The amount of radioactive cesium in the fish is not thought to be damaging to people if consumed, the researchers said in a study published in the journal Proceedings of the National Academy of Sciences.
Without making a definitive judgment on the safety of the fish, lead author Daniel Madigan of Stanford University's Hopkins Marine Station noted that the amount of radioactive material detected was far less than the Japanese safety limit.
"I wouldn't tell anyone what's safe to eat or what's not safe to eat," Madigan said in a telephone interview. "It's become clear that some people feel that any amount of radioactivity, in their minds, is bad and they'd like to avoid it. But compared to what's there naturally ... and what's established as safety limits, it's not a large amount at all."
Low dose radiation is harmful. There is no completely safe level. Previous videos and articles on this blog have explained the science. Although the damage from Caesium is slight, there are adverse health effects over the longer term.
Plus, we know that radioactive fallout from Fukushima has been detected all over the northern hemisphere - much of it occurring in the days following the 3 complete meltdowns. This is exactly like Chernobyl.
