Radiation poisoning, also called "radiation sickness" or a "creeping dose", is a form of damage to organ tissue due to excessive exposure to ionizing radiation. The term is generally used to refer to acute problems caused by a large dosage of radiation in a short period, though this also has occurred with long-term exposure to low-level ...
One of the most severe long-term effects the survey found is an increase in rates of suicide. [3] In the first few years after the disaster, suicide rates decreased, but after 2013, there was a significant increase in the rate of suicide that surpassed the rate of suicide in the year before the disaster.
The statement also called for "extending the current 20-km mandatory evacuation zone radically to avoid further exposure and discontinuing official declarations that there is no immediate harm to human health, charging they aren't properly transmitting to the public the dangers of possible long-term radiation harm".
The Radiation Effects Research Foundation (RERF) is a joint U.S.-Japan research organization responsible for studying the medical effects of radiation and associated diseases in humans for the welfare of the survivors and all humankind. [1] The organization's scientific laboratories are located in Hiroshima and Nagasaki, Japan.
Radiation is a moving form of energy, classified into ionizing and non-ionizing type. [4] Ionizing radiation is further categorized into electromagnetic radiation (without matter) and particulate radiation (with matter). [4] Electromagnetic radiation consists of photons, which can be thought of as energy packets, traveling in the form of a wave ...
The report also called for measures tackling public health and welfare issues, including the establishment of a system "to deal with long-term public health effects," monitoring "hot spots" and "the spread of radioactive contamination", and for starting "a detailed and transparent program of decontamination and relocation."
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]
Natural radiation levels are higher in some part of the world than the projected level mentioned above, and about 4 people out of 10 can be expected to develop cancer without exposure to radiation. [70] [71] Further, the radiation exposure resulting from the accident for most people living in Fukushima is so small compared to background ...
