WASHINGTON (AFP) - Elevated levels of cesium found in fish off Japan's east coast 18 months after the Fukushima nuclear disaster suggest a "continuing source" of radiation in the ocean, a new study has revealed .

Marine chemist Ken Buesseler of the Woods Hole Oceanographic Institution reviewed official Japanese data on radiation levels in fish, shellfish and seaweed collected near the crippled nuclear plant.

Mr Buesseler concluded the lingering contamination may be due to low-level leaks from the facility or contaminated sediment on the ocean floor, according to his research, published on Thursday in the US magazine Science.

He estimated that about 40 percent of fish caught near Fukushima are considered unfit for consumption under Japanese regulations.
