One would think that three years on the amount of radiation headed to Hawaii's waters would be declining...... not the case

(Reuters) - The operator of Japan's wrecked Fukushima nuclear plant knew about record high measurements of a dangerous isotope in groundwater at the plant for five months before telling the country's nuclear watchdog, a regulatory official told Reuters.
Tokyo Electric Power Co (Tepco) said late on Wednesday it detected 5 million becquerels per liter of radioactive strontium-90 in a sample from a groundwater well about 25 meters from the ocean last September
Strontium-90, which has a half-life of around 29 years, is estimated to be twice as harmful to the human body as cesium-137, another isotope that was released in large quantities during the meltdowns at the Fukushima Daiichi plant in March 2011. The legal limit for releasing strontium into the ocean is 30 becquerels per liter.
Tepco has been heavily criticized for its inept response to the 2011 disaster at Fukushima, including delays in releasing radiation data. The NRA's chairman said on Wednesday that Tepco still lacks a fundamental understanding of measuring and handling radiation.
