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. Some of them serve as part of a national monitoring network for use in a nuclear emergency.
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.
Radioactive gas levels stayed high in the area even after the plant was sealed. Finally, on October 12, it was discovered that a roof ventilation fan had been left on and it was shut down. [22] Sometime after the incident, people in the area were asked to lend any gold they had to allow calculations of the size and range of the gamma ray burst ...

With an area size of 13,784 km 2 (5,322 sq mi) it is the third-largest prefecture of Japan, behind Hokkaido and Iwate Prefecture. It is divided by mountain ranges into three regions called (from west to east) Aizu, Nakadōri, and Hamadōri. Fukushima city is located in the Fukushima Basin's southwest area and nearby mountains. Located on the ...
In April 2023, Japan's NRA announced a Comprehensive Radiation Monitoring Plan, in which the concentration of radionuclides in food (land and sea), soil, water, and air will be continually monitored across Japan. NRA also set up a system to monitor the radionuclide concentration in ALPS-processed water in order to verify TEPCO's readings.
