The government set its first radiation safety standards for fish Tuesday after Japan's tsunami-ravaged nuclear plant reported radioactive contamination in nearby seawater measuring at several million times the legal limit.
The new levels coupled with reports that radiation was building up in fish led the government to create an acceptable radiation standard for fish for the first time. Some fish caught Friday off Japan's coastal waters would have exceeded the new provisional limit.
Also Tuesday, TEPCO announced that samples taken from seawater near one of the reactors contained 7.5 million times the legal limit for radioactive iodine on April 2. Two days later, that figure dropped to 5 million.
