Hisashi Ouchi, The Radioactive Man Kept Alive For 83 Days
Hisashi Ouchi Suffered History's Worst Radiation Burns — Then Doctors Kept Him Alive For 83 Excruciating Days Against His Will. After a fateful accident at Japan's Tokaimura nuclear power plant in 1999, Hisashi Ouchi lost most of his skin and began crying blood before his agony finally ended.
Hisashi Ouchi Suffered an 83-day Death By Radiation Poisoning
On the morning of Sept. 30, 1999, at a nuclear fuel-processing plant in Tokaimura, Japan, 35-year-old Hisashi Ouchi and two other workers were purifying uranium oxide to make fuel rods for a research reactor.. As this account published a few months later in The Washington Post details, Ouchi was standing at a tank, holding a funnel, while a co-worker named Masato Shinohara poured a mixture of ...

Unit 731 (Japanese: 731部隊, Hepburn: Nana-san-ichi Butai), [note 1] short for Manchu Detachment 731 and also known as the Kamo Detachment [3]: 198 and the Ishii Unit, [5] was a covert biological and chemical warfare research and development unit of the Imperial Japanese Army that engaged in lethal human experimentation and biological weapons manufacturing during the Second Sino-Japanese War ...

Tokaimura nuclear accidents
Tokai Nuclear Plant, Japan's first nuclear power station. The Tokaimura nuclear accidents refer to two nuclear related incidents near the village of Tōkai, Ibaraki Prefecture, Japan.The first accident occurred on 11 March 1997, producing an explosion after an experimental batch of solidified nuclear waste caught fire at the Power Reactor and Nuclear Fuel Development Corporation (PNC ...
Hisashi Ouchi, the Victim of Fatal Radiation Kept Alive for 83 Days
Shinohara (29 years), who stood on the platform beside the tank to help Ouchi, received 10 sieverts. A lethal dose of radiation is 7 sieverts, and the maximum allowable annual dosage for Japanese nuclear workers was 50 millisieverts. Yokokawa, aged 54, who was shielded by the walls and distance, received 3 sieverts.
The Man Kept Alive Against His Will: Hisashi Ouchi
As soon as the Gamma radiation alarms sounded, the three technicians knew they made a mistake. All three were exposed to deadly levels of radiation; more specifically, Ouchi received 17 Sv of radiation due to his proximity to the reaction, Shinohara 10 Sv, and Yokokawa 3 Sv due to his placement at a desk several meters away from the accidents.
Experimental Treatment for Japanese Radiation Victim
TOKAIMURA, JAPAN--As life here returns to normal this week after the country's worst-ever nuclear accident, the worker blasted with the highest radiation dose is being readied for an experimental therapy that may be his best chance for surviving the accident.He is scheduled to receive a transfusion of his brother's blood stem cells on Wednesday. The 30 September incident at a nuclear fuel ...

Aftermath. By allowing scientists to study their suffering, atomic bomb survivors have transformed our understanding of radiation's health effects. A mushroom cloud hangs over Hiroshima on 6 August 1945. An estimated 90,000 to 120,000 people died that day or soon after; many others developed cancer later.
Hiding The Radiation of the Atomic Bombs
The atomic bombing of Hiroshima and Nagasaki by the U.S. came with censorship and obfuscation about the effects of the radiation on those who were exposed. The radioactive plume from the bomb dropped on Nagasaki City, as seen from 9.6 km away, in Koyagi-jima, Japan, August 9, 1945. The icon indicates free access to the linked research on JSTOR ...
Hiroshima and Nagasaki: The Long Term Health Effects
The Radiation Effects Research Foundation estimates the attributable risk of leukemia to be 46% for bomb victims. For all other cancers, incidence increase did not appear until around ten years after the attacks. The increase was first noted in 1956 and soon after tumor registries were started in both Hiroshima and Nagasaki to collect data on ...
Criticality accident
Criticality accident. A criticality accident is an accidental uncontrolled nuclear fission chain reaction. It is sometimes referred to as a critical excursion, critical power excursion, divergent chain reaction, or simply critical. Any such event involves the unintended accumulation or arrangement of a critical mass of fissile material, for ...

Measuring the Particular
Following the shock of the 1954 thermonuclear weapon test at Bikini Atoll, Japanese scientists rallied to study the effects of low levels of radiation on life. Given the challenge of generalizing experimental results based on the particularities of different test organisms, research methods, and environments in Japan, geneticists grappled with how to extract reliably universal knowledge about ...
Human radiation experiments
Human radiation experiments. Joseph G. Hamilton was the primary researcher for the human plutonium experiments done at U.C. San Francisco from 1944 to 1947. [ 1] Hamilton wrote a memo in 1950 discouraging further human experiments because the AEC would be left open "to considerable criticism," since the experiments as proposed had "a little of ...

Radiation Experiments On Humans: When And Why It Happened
Any exposure to plutonium raises your risk of cancer over a lifetime, and high doses cause enough damage to kill over a range of seconds to months, depending on the dose received. On top of the radiation threat, plutonium is also a heavy metal, like lead or mercury, and is about as toxic as both. A 150-pound adult who consumes 22 mg of ...
Health effects of Japan's radiation crisis
By P.J. Skerrett, Editor, Harvard Heart Letter. One of the most abundant ingredients released by Japan's failing nuclear power plants is radioactive iodine-131. It can get into the air, water, and food supply. Once in the body, iodine-131 accumulates in the thyroid gland and significantly increases the risk of developing thyroid cancer.
High-Energy Physics Experiments in Japan Weather the Crises
This is to protect both American-Japanese collaboration experiments from solar radiation that would obscure their data. Although the KamLAND detector uses Japanese nuclear reactors as its neutrino source, Freedman says that the loss of the Fukushima reactor and ensuing radiation will affect the experiments little. The biggest problem for high ...
A New Framework for Synchrotron Radiation Studies in the EIC Experiment
The Electron-Ion Collider (EIC) is a cutting-edge particle accelerator aimed at investigating the fundamental structure of matter by colliding high-energy polarized electron beams with ions. To explore dense gluon systems and uncover the origins of nucleon mass and spin, the EIC will operate at high beam currents and luminosities. However, this approach raises beam-induced background rates ...
