Jupiter is the most radioactive planet.
As a result of the strong magnetic field, Jupiter's radiation belts are much more dangerous than Earth's belts. NASA has estimated that if astronauts were to ever venture as close to Jupiter as did the Voyager 1 spacecraft, the astronauts would receive a dose 1,000 times greater than the lethal dose.
As Francis Nimmo, professor of Earth and planetary sciences at UCSC and first author on the study, explained in a UCSC Newscenter release: “What we realized was that different planets accumulate different amounts of these radioactive elements that ultimately power geological activity and the magnetic field.
1. Fukushima Daini Nuclear Power Plant, Japan is one of the world's most radioactive places. Fukushima is still highly radioactive today.
Strong currents in the magnetosphere generate permanent aurorae around the planet's poles and intense variable radio emissions, which means that Jupiter can be thought of as a very weak radio pulsar.
While a spacecraft would have nowhere to land on Jupiter, it wouldn't be able to fly through unscathed either. The extreme pressures and temperatures deep inside the planet crush, melt, and vaporize spacecraft trying to fly into the planet.
The theory goes that Jupiter pushes these dangerous comets out of their murder orbits so they don't smash into Earth and kill us all. But a competing theory says that Jupiter actually diverts comets that would have completely missed our planet into deadly, Earth-killing trajectories.
According to a report by the Worldwatch Institute on nuclear waste, Karachay is the most polluted (open-air) place on Earth from a radiological point of view.
Chernobyl reactor 4 is no longer burning. The reactor was originally covered after the disaster, but it resulted in a leak of nuclear waste and needed to be replaced.
The answer is a definitive no. After the Hiroshima and Nagasaki bombs, residual radiation was left behind but this declined rapidly. According to the city of Hiroshima local government website, research has indicated that 80 percent of residual radiation was emitted within 24 hours of the bombing.
Then, just last year, scientists discovered another Earth-like planet orbiting one of our closest neighboring stars, Proxima Centauri. Currently, this planet is the best candidate we have for supporting human life.
Saturn, Uranus, and Neptune:
As with Jupiter, you'd descend into these gas giants and ultimately be crushed by the pressure. Nope, not even the rings of Saturn would provide you with a stable surface to walk on. Bummer.
One theory of solar system formation is that there are more metals in the inner solar system. That would mean most of the uranium is Mars, Mercury, Earth Venus and asteroid belt. There is an estimated 40 trillion tons of Uranium and 120 trillion tons of thorium in the Earth's crust.
The Latest. Venus has a thick, toxic atmosphere filled with carbon dioxide and it's perpetually shrouded in thick, yellowish clouds of sulfuric acid that trap heat, causing a runaway greenhouse effect. It's the hottest planet in our solar system, even though Mercury is closer to the Sun.
Chernobyl, Ukraine
Much of it spread to Belarus, Ukraine, and into the rest of Northern Europe. About 116,000 people were relocated as a result, including those from the nearby town of Pripyat. Today, you can visit Chernobyl, but pockets of radiation around the site remain.
A: Besides Earth, Mars would be the easiest planet to live on. Mars has liquid water, a habitable temperature and a bit of an atmosphere that can help protect humans from cosmic and solar radiation. The gravity of Mars is 38% that of the Earth.
More than 30 years on, scientists estimate the zone around the former plant will not be habitable for up to 20,000 years. The disaster took place near the city of Chernobyl in the former USSR, which invested heavily in nuclear power after World War II.
Chernobyl animals are mutants ...
Among breeding birds in the region, rare species suffered disproportional effects from the explosion's radiation compared to common species.
How Long Will It Take For Ground Radiation To Break Down? On average, the response to when Chernobyl and, by extension, Pripyat, will be habitable again is about 20,000 years.
"Compared with other nuclear events: The Chernobyl explosion put 400 times more radioactive material into the Earth's atmosphere than the atomic bomb dropped on Hiroshima; atomic weapons tests conducted in the 1950s and 1960s all together are estimated to have put some 100 to 1,000 times more radioactive material into ...
The Fukushima accident was an accident in 2011 at the Fukushima Daiichi (“Number One”) nuclear power plant in Japan. It is the second worst nuclear accident in the history of nuclear power generation, behind the Chernobyl disaster.
The accident at Fukushima occurred after a series of tsunami waves struck the facility and disabled systems needed to cool the nuclear fuel. The accident at Chernobyl stemmed from a flawed reactor design and human error. It released about 10 times the radiation that was released after the Fukushima accident.
While Jupiter often protects Earth and the other inner planets by deflecting comets and asteroids, sometimes it sends objects on a collision course straight toward the inner planets.
But their elongated orbits can be strongly perturbed by Jupiter's gravity. In fact, the massive planet flings some comets out of the solar system altogether. That's why astronomers suggested in the early 1990s that Jupiter serves as a sort of planetary bodyguard for Earth.
Meanwhile, as meteoroids infiltrate the rings, they push material within the innermost rings toward Saturn at a rapid rate. Cassini observed that the rings were losing many tons of mass per second, which means the rings don't have much time left, astronomically speaking.
