Japan’s radiation problem keeps getting worse. Radioactive Iodine and Cesium and pouring into the Pacific Ocean, and while experts are trying to be reassuring they are going about it in a decidedly worrying fashion.
Very close to the nuclear plant — less than half a mile or so — sea creatures might be in danger of problems like genetic mutations if the dumping goes on a long time, he said. But there shouldn’t be any serious hazard farther away “unless this escalates into something much, much larger than it has so far,” he said.
No fishing is allowed in the vicinity of the complex.
He agreed that animals near the plant may be affected. It’s not clear in what way, because the level of radiation isn’t well known, he said. In any case, fish would probably escape such an effect because unlike immobile species such as oysters, they move around and so would not get a continuous exposure, he said.
How can they say the fish nearby will be protected “because they move” and then only prohibit fishing in the area affected? If the fish are safe, why prohibit fishing at all? If not, why limit it to the area around the plant (rather than institute radiation testing). Actually, that is just what they are planning on doing next. Setting radiation safety levels for seafood:
Experts agree that radiation dissipates quickly in the vast Pacific
He added that seawater may be diluting the iodine, which decays quickly, but the leak also contains long-lasting cesium-137, which can build up in fish over time. Both can build up in fish, though iodine’s short half-life means it does not stay there for very long. The long-term effects of cesium, however, will need to be studied, he said.
They really have no idea what the long term effects of this will be. They don’t know the range of impact either: Fish Migrate.
Meanwhile their plans involve trying desperately to find the leak, and making increasingly desperate and risky decisions:
The government on Monday gave the go-ahead to pump more than 3 million gallons of less-contaminated water into the sea — in addition to what is leaking — to make room at a plant storage facility to contain more highly radioactive water.
What happens when that storage facility fills up again? Given the constantly shifting truths about just what is leaking, and what its long term impact might be – how do we know what to believe?
