A June 2012 Stanford University study estimated, using a linear no-threshold model, that the radioactivity release from the Fukushima Daiichi nuclear plant could cause 130 deaths from cancer globally (the lower bound for the estimate being 15 and the upper bound 1100) and 199 cancer cases in total (the lower bound being 24 and the upper bound ...
On 20 December the Ministry of Environment announced an extra program to monitor the impact of radiation exposure on children born to mothers in Fukushima Prefecture, to find links between the mothers' radiation exposure and congenital abnormalities, asthma, allergies or other diseases of their children.
Radiation exposure of those living in proximity to the accident site was estimated at 12–25 mSV in the year following the accident. [134]: 8 Residents of Fukushima City were estimated to have received 4 mSv in the same time period. [135] In comparison, the dosage of background radiation received over a lifetime is 170 mSv. [136]
Radiation exposure to workers at the plant was projected to result in 2 to 12 deaths. The radioactivity released was an order of magnitude lower than that released from Chernobyl, and some 80% of the radioactivity from Fukushima was deposited over the Pacific Ocean; preventive actions taken by the Japanese government may have substantially ...
The situation with the Fukushima Daiichi nuclear plant has frayed more than a few nerves around the world, especially after food, water and seawater in Japan were found to be contaminated with ...
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 TÅhoku earthquake on 11 March 2011 and manages a global open data network for ionizing radiation and air quality monitoring.
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.
The Soviet Union conducted 456 nuclear tests at Semipalatinsk from 1949 until 1989 with little regard for their effect on the local people or environment. The full impact of radiation exposure was hidden for many years by Soviet authorities and has only come to light since the test site closed in 1991. [59] 2007 ISO radioactivity danger symbol ...
