They will never be fully 'cleaned up' the effects of radiation of the bomb is ever present with people still dying because of leukemia and other effects.
In the related links box below, I posted a site with the truth of this statement.

The only method on cleaning the radiation is time. Once the radiation is in the air, it takes years to disperse.
You clean it like you clean a cast iron fry pan. Wipe it down after each bureaucrat and it is ready for the next one.
to clean up evidence
There is no real "time" period that it took to clean up, because people have different views about different places. Some parts of the cities were covered in weeks, while some took months. It took almost a year for the radiation to fully go away in some areas. In the US, the cost of cleaning up the radioactive pollution created by the nuclear weapons complex has been estimated at US $ 365 billion, almost as much as the cost of building a nuclear weapon.
After the Japanese surrendered it was clear that the US was the winner.
The atomic bomb explosion in Hiroshima caused severe damage to the city's infrastructure, including its water supply system. Many pipelines were destroyed, contaminating the water with radioactive materials and rendering it unsafe for consumption. This resulted in a lack of clean water for survivors, exacerbating the humanitarian crisis in the aftermath of the bombing.

They attacked Serbia as it was clean and peaceful so it wasn't reliable on America until they bombed Serbia
It took several decades to clean up all the rubble done by bombing and shooting.
It depends on its use. creation of atomic energy is very clean and only the waste products are harmful there is also the problem of metdowns. as i said before it really depends on context and your opinion
Atomic energy is a clean source of energy that produces low emissions, making it environmentally friendly. It also has a high energy output, providing a reliable and efficient source of electricity. Additionally, atomic energy can help reduce dependency on fossil fuels and mitigate climate change.
There has been protests raising questions about atomic energy as a clean and safe alternative to fossil fuels.
Not only that, the US spent 15 years building the country because they had no resources to build the nation again. The US also fed the Japanese for those years.
Atomic energy is the energy released from splitting (nuclear fission) or combining (nuclear fusion) atoms. It is used in nuclear power plants to generate electricity and in nuclear weapons for explosive purposes. The use of atomic energy has both benefits, such as providing a relatively clean energy source, and concerns, such as nuclear accidents and nuclear proliferation.
Fusion occurs when two atomic nuclei collide. The reaction that is produce by the collision can be used to provide energy. Fusion is the reaction that powers most active stars in the universe.
