Hisashi Ouchi, a victim of nuclear radiation from Tokaimura (2024)

FAQs

Hisashi Ouchi, a victim of nuclear radiation from Tokaimura? ›

Hisashi Ouchi, 35, was transported and treated at the University of Tokyo Hospital for 83 days. Ouchi suffered serious radiation burns to most of his body, experienced severe damage to his internal organs, and had a near-zero white blood cell count.

Kept in a special radiation ward to protect him from hospital-borne pathogens, Hisashi Ouchi leaked fluids and cried for his mother. He regularly flatlined from heart attacks, only to be revived at the insistence of his family. His only escape would be a final cardiac arrest — 83 long days later.

On September 20, 1999, a nuclear reaction occurred at the Tokaimara Uranium Processing plant, about 90 miles northwest of Tokyo. While processing uranium with nitric acid to make nuclear fuel, workers bypassed several safety steps, and mixed too much uranium and set off the accidental uncontrolled reaction.

The walking ghost phase of radiation poisoning is a period of apparent health, lasting for hours or days, following a dose of 10-50 sieverts of radiation. As its name would suggest, the walking ghost phase is followed by certain death.

Hisashi Ouchi, aged 35, died 12 weeks after the accident. He had lost most of his skin, and was kept alive for 83 days, according to his parents and wife will. Ouchi was closest to the tank when the accident occurred.

Hisashi Ouchi was exposed to about 17 sieverts and was kept alive for 83 days. In a freak nuclear accident that took place in September 1999, a man was introduced to the highest level of radioactive material.

Hisashi Ouchi, 35, was transported and treated at the University of Tokyo Hospital for 83 days. Ouchi suffered serious radiation burns to most of his body, experienced severe damage to his internal organs, and had a near-zero white blood cell count.

Is Chernobyl still radioactive? Yes, the area surrounding Chernobyl remains radioactive. Referred to as the "exclusion zone," this 20-mile radius around the plant has largely been evacuated and is closed to human habitation. Despite government prohibitions, some residents have returned their homes.

There is consensus that a total of approximately 30 people died from immediate blast trauma and acute radiation syndrome (ARS) in the seconds to months after the disaster, respectively, with 60 in total in the decades since, inclusive of later radiation induced cancer.

Albert Stevens (1887–1966), also known as patient CAL-1 and most radioactive human ever, was a house painter from Ohio who was subjected to an involuntary human radiation experiment and survived the highest known accumulated radiation dose in any human.

Why is radiation so scary? ›

Many find radiation scary, especially when it is associated with a nuclear power station, despite the fact that there is no difference between natural radiation and 'man-made' radiation. After an incident involving radiation, many become anxious because they cannot see, touch or smell it.

The direct and indirect effect of high-dose radiotherapy (RT) on the periodontium results in greater risk of periodontal attachment loss and tooth loss and greater risk for the development of osteoradionecrosis [7].

Albert Stevens (1887–1966), also known as patient CAL-1 and most radioactive human ever, was a house painter from Ohio who was subjected to an involuntary human radiation experiment and survived the highest known accumulated radiation dose in any human.

Ouchi died of his wounds about 80 days after receiving a horrendously huge acute dose of gamma and neutrons. His exposure was due to the prompt criticality of uranium caused by a mixing tank mishap. He survived for the relatively long time of 80 days only because of “heroic" medical interventions.

Blue glow. It has been observed that many criticality accidents emit a blue flash of light. The blue glow of a criticality accident results from the fluorescence of the excited ions, atoms and molecules of the surrounding medium falling back to unexcited states.

High levels of exposure are dangerous

If people are exposed to 4 to 7 Sievert (Sv) of radiation in an instant, a half of those people will die within 30 days. This is equivalent to the amount received by people within 1100 meters of the hypocenter in Hiroshima.
