In December 2011, as Japan completed "step 2" of its control roadmap at Fukushima, U.S. NRC chairman Jaczko visited the plant and said afterwards "that there was no longer enough energy in the reactors at the crippled Fukushima No. 1 Nuclear Power Plant to produce an offsite release of radiation, but pointed out that a large cleanup task remained".
Because of the short half-life of 8 days only 400 locations were still positive. This map showed that iodine-131 spread northwest of the plant, just like caesium-137 as indicated on an earlier map. But I-131 was also found south of the plant at relatively high levels, even higher than those of caesium-137 in coastal areas south of the plant.
Cesium (Cs-137) is the primary isotope released from the Fukushima Daiichi facility. [160] Cs-137 has a long half-life, meaning it could potentially have long-term harmful effects, but as of now, its levels from 200 km outside of Fukushima show close to pre-accident levels, with little spread to North American coasts.

The 9.0 magnitude quake and tsunami that ravaged parts of Japan’s northeastern coast on March 11, 2011 killed about 20,000 people and drove thousands from their homes in the prefectures of ...
Tokyo will set aside several trillion yen in public funds that TEPCO can "dip into if it runs short for payouts to people affected". [87] Starting at 22 March 2011 TEPCO compiled a radiation map of the surroundings of the Fukushima Daiichi nuclear power plant. At 150 spots around the buildings the radiation was monitored.
A massive March 11, 2011, earthquake and tsunami destroyed the Fukushima Daiichi plant’s cooling systems, causing three reactors to melt and contaminating their cooling water.
The plant with seven units is the largest single nuclear power station in the world, which now again is shut down due to the Fukushima accident. [47] 0: 1 Dec 2009: Hamaoka, Japan: Leakage accident of radioactive water. 34 workers were exposed to radiation: 0: Mar 2011: Fukushima Dai-ichi, Japan: The world's second INES 7 accident.
Hundreds of people marched in South Korea’s capital on Saturday demanding Japan scrap its plans to release treated wastewater from the damaged Fukushima nuclear power plant, as the head of the U ...
