Does the radiation from the crippled Fukushima nuclear plant pose a health risk to Americans?

It's a question that many people are asking nearly three years after a massive tsunami struck Japan.

This morning on Fox and Friends, Clayton Morris sat down with Dr. Nicholas Fisher, a marine biologist who led a study of the radiation risks in the Pacific Ocean.

He said the levels of radiation are much higher in waters off Japan, compared to waters off California. Fisher said that some people "choose to be worried" about the radiation, but that the levels of radiation found in fish off the coast of San Diego have been "very low."

"Let's put that in perspective. The dose is far below the dose from naturally occurring radionuclides that are present in the same fish," said Fisher, adding that low levels of radioactive materials, like polonium-210, are present in all marine life.

He said that he has no qualms about eating fish caught off the coast of California.
