What are the effects of nuclear testing?
In terms of human health exposure, specialized studies have shown that thyroid cancer (generally, papillary thyroid cancer) is the most important consequence of nuclear tests, mainly due to radionuclide 131I (UNSCEAR 2006).
How far does a nuclear bomb go?
The dangerous fallout zone can easily stretch 10 to 20 miles (15 to 30 kilometers) from the detonation depending on explosive yield and weather conditions.
Why are nuclear tests banned?
The impetus for the test ban was provided by rising public anxiety over the magnitude of nuclear tests, particularly tests of new thermonuclear weapons (hydrogen bombs), and the resulting nuclear fallout. A test ban was also seen as a means of slowing nuclear proliferation and the nuclear arms race.
Why nuclear test is done secretly?
Preparations for the test
The Indian Intelligence Agency had been aware of United States spy satellites and the CIA had been detecting Indian test preparations since 1995. Therefore, the tests required complete secrecy in India and also needed to avoid detection by other countries.

Can nuclear bombs be stopped?
Halting an atomic weapon is theoretically possible, say experts, but in reality is an enormous challenge. The Russian invasion of Ukraine has raised the fear of nuclear weapons to a level not seen since the Cold War.
Why did the US stop testing nuclear weapons?
When the Cold War ended, the U.S. pledged to stop doing such tests and a group within the United Nations began putting together the CTBT. The goal of the test ban treaty was to hinder new nations from developing nuclear arsenals and limit the capabilities of nations that already had them.

Once inside, get as far away from the windows as you can. Make your way to the basement, if there is one, or to the stairwell, usually the sturdiest part of any building. In the wake of the blast, you would have about 15 minutes before radioactive particles started raining down.

New START limits all Russian deployed intercontinental-range nuclear weapons, including every Russian nuclear warhead that is loaded onto an intercontinental-range ballistic missile that can reach the United States in approximately 30 minutes.
Which country first tested nuclear bomb?
16 July 1945 – ‘Trinity’: world’s first nuclear test
The first-ever nuclear bomb was detonated in New Mexico, at the Alamogordo Test Range. Nicknamed the “gadget”, the plutonium-based implosion-type device yielded 19 kilotons, creating a crater over 300 metres wide.

What is worse than an atomic bomb?
But a hydrogen bomb has the potential to be 1,000 times more powerful than an atomic bomb, according to several nuclear experts. The U.S. witnessed the magnitude of a hydrogen bomb when it tested one within the country in 1954, the New York Times reported.
