Chernobyl's No. 1, 2, and 3 reactors are currently undergoing a decades-long decommissioning, after they continued operation for several years following Reactor No. ... Meanwhile, Reactor No. 4, now covered by the New Safe Confinement, is estimated to remain highly radioactive for up to 20,000 years.

By no means, is the elephant's foot still sinking?
It's made up of nuclear fuel, melted concrete and metal, and was formed during the initial accident. The foot is still active. In '86 the foot would have been fatal after 30 seconds of exposure; even today, the radiation is fatal after 300 seconds.
In all cases, is Pripyat safe now? Yes. The site has been open to the public since 2011, when authorities deemed it safe to visit. While there are Covid-related restrictions in Ukraine, the Chernobyl site is open as a “cultural venue”, subject to extra safety measures.
Apart from this, how many years until Fukushima is safe?
It could take 30 years or more to remove the nuclear fuel, dismantle the reactors, and remove all the buildings.
Who took the elephant's foot photo?
It is probably about 2–300 degrees internally, well below any component's melting point. Both of the pictures were taken with an auto-timed camera taken into the room in 1996 by Artur Korneyev, a Kazakh official at Chernobyl.

To this day, more than 7,000 people live and work in and around the plant, and a much smaller number have returned to the surrounding villages, despite the risks.
Historically and geographically, the zone is the heartland of the Polesia region. This predominantly rural woodland and marshland area was once home to 120,000 people living in the cities of Chernobyl and Pripyat as well as 187 smaller communities, but is now mostly uninhabited.
Today, over 1.6 million people live and seem to be thriving in Hiroshima and Nagasaki, yet the Chernobyl exclusion zone, a 30 square kilometer area surrounding the plant, remains relatively uninhabited.
According to the International Atomic Energy Agency (IAEA), there was less total atmospheric release of radioactivity from the Fukushima accident compared with Chernobyl due to the different accident scenarios and mechanisms of radioactive releases.
In April 1986, an accidental reactor explosion at the Chernobyl nuclear power plant in present-day Ukraine exposed millions of people in the surrounding area to radioactive contaminants. “Cleanup” workers were also exposed. Such radiation is known to cause changes, or mutations, in DNA.
The Elephant's Foot is a mass of black corium with many layers, externally resembling tree bark and glass. It was formed during the Chernobyl disaster in April 1986 and discovered in December 1986. It is named for its wrinkly appearance, resembling the foot of an elephant. ... 4 of the Chernobyl Nuclear Power Plant.
Children of Chernobyl Today There has been a 200 percent increase in birth defects and a 250 percent increase in congenital birth deformities in children born in the Chernobyl fallout area since 1986.
The Elephant's Foot is so deadly that spending only 30 seconds near it will result in dizziness and fatigue. Two minutes near it and your cells will begin to hemorrhage. ... Even after 30 years, the foot is still melting through the concrete base of the power plant.
Born of human error, continually generating copious heat, the Elephant's Foot is still melting into the base of the Chernobyl nuclear power plant. If it hits ground water, it could trigger another catastrophic explosion or leach radioactive material into the water nearby residents drink.
It depends on which part of Chernobyl you're talking about. The highly publicized number is 20,000 years, but that refers specifically to the Elephant's Foot, the highly radioactive remains of the reactor itself. In a broader sense, it's harder to pin down how long it will be until Chernobyl is completely safe.
Hiroshima/Nagasaki is Definitely Safe for People to Live in Today. The horror of World War II are undeniable, but more than 75 years have now passed since the bombings.

Japan's government announced a decision to begin dumping more than a million tons of treated but still radioactive wastewater from the crippled Fukushima nuclear plant into the Pacific Ocean in two years.
With dilution the treated water poses no scientifically detectable risk, they say. While the tritium is radioactive, it has a half-life of around 12 years, meaning it will disappear from the environment over a period of decades rather than centuries.
So if you are given some Hokkaido (1) scallop or Kanpachi/Hamachi which are harvested from the fish farms in Kagoshima (46), you can be assured that they are still very safe.
Today, it still radiates heat and death, and is therefore still very dangerous. Fortunately, it is sealed under the New Safe Confinement, so visiting the Chernobyl Power Plant and working near the new sarcophagus is safe.
New, unused fuel rods can be touched, they're not that radioactive. Here's one: It consists of uranium dioxide, and it emits alpha radiation, which cannot penetrate the skin. It isn't exactly healthy, so you should not touch it … but it isn't that unsafe.
Dr de Geer wrote in the study: “It is well known that criticality accidents emit a blue flash, or rather glow, which derives from fluorescence of excited oxygen and nitrogen atoms in the air. ... “With the fuel fully exposed, the air was irradiated, and the typical blue glow was lit.”
