Fukushima I and II Nuclear Accidents Overview Map showing evacuation and other zone progression and selected radiation levels. The Japanese reaction occurred after the Fukushima Daiichi nuclear disaster, following the 2011 Tōhoku earthquake and tsunami. A nuclear emergency was declared by the government of Japan on 11 March.
In the first week of September the Ministry of Science published a new map showing radiation levels in Fukushima and four surrounding prefectures, based on the results of an aerial survey. In the map, different colors were used to show the level of radiation at locations one meter above the ground. Red: 19 microsieverts per hour or higher.
Radiation levels in Japan are continuously monitored in a number of locations, and a large number stream their data to the internet. Some of these locations are mandated by law for nuclear power plants and other nuclear facilities.
In February 2018, Japan renewed the export of fish caught off Fukushima's nearshore zone. According to prefecture officials, no seafood had been found with radiation levels exceeding Japan safety standards since April 2015. In 2018, Thailand was the first country to receive a shipment of fresh fish from Japan's Fukushima prefecture. [163]
Maximum level of radiation detected: 300 Sv/h shortly after the explosion in vicinity of the reactor core. [8] 530 Sv/h inside Unit 2 containment vessel in 2017 according to Japan Times. [9] Radioactivity released: According to IAEA, total release was 14 EBq (14,000 PBq). [10] 5.2 EBq (5,200 PBq) in iodine-131 equivalent [11] [12]
Safecast is an international, volunteer-centered organization devoted to open citizen science for environmental monitoring.Safecast was established by Sean Bonner, Pieter Franken, and Joi Ito shortly after the Fukushima Daiichi nuclear disaster in Japan, following the Tōhoku earthquake on 11 March 2011 and manages a global open data network for ionizing radiation and air quality monitoring.
The first of the typhoons of the season is due to strike the area, while Japan states radiation levels at the seabed are several hundreds of times above normal levels off the coast of Fukushima. "The Science Ministry announced late on Friday highly radioactive materials were detected in a 300-km north-south stretch from Kesennuma in Miyagi ...
On 25 March 2011, officials announced the reactor vessel might be breached and leaking radioactive material. High radiation levels from contaminated water prevented work. [53] Japan Nuclear and Industrial Safety Agency (NISA) reiterated concerns about a Unit 3 breach on 30 March. [54]
