Why is Japan saying that the iodine in the ocean would “disappear” (half-life) after a while
· Radioactive iodine has a brief half-life
o Become diluted in the ocean
o Decay too quickly to be detected in fish
· Iodine have shorter half-lives
o Not as dangerous because it can take weeks for fish to make it to supermarkets and restaurants
· However, there are findings that raised doubts
o Leak also contained long-lasting cesium
§ Build up in fish
· Have a negative impact on people in near future
