Many, but the US Buster-Jangle Uncle effects test was the first. It was 1.2KTons exploded at a depth of about 3 feet, to test cratering effects. It produced massive fallout levels. Most underground testing is done much deeper to prevent contamination.

Which country exploded first its nuclear device?
All countries that have exploded nuclear devices have exploded their first devices. The USA was the first to detonate such a device and the only country to use nuclear warheads in combat. The most recent countries to test nuclear devices are India, Pakistan, and North Korea.
Where was the first nuclear bomb made?
Both the first fission bomb (the Gadget device exploded in Trinity test July 16, 1945 on a 100 foot tall steel tower in the Jornada del Muerto valley in what is now White Sands Missile Range) and the first fusion bomb (the Sausage device exploded in Ivy Mike test November 1, 1952 on the surface at Enewetak Atoll) were designed and made at Los Alamos in New Mexico.
Effect of nuclear weapons on a country?
The use of a nuclear weapon on a country would be considered devestating, dependant on the payload and method of delivery of the nuclear device. It can destroy cities, and make the land infertile for many years afterwards please look towards Nagasaki and Hiroshima for more information. The "effect" of nuclear weapons on a country would depend on what your perspective is: there is something called MAD (Mutually Assured Destruction) of which the cold war is an example, where the development of a nuclear arsenal by one country (USSR) was profilgate in the development of a nuclear arsenal in another country (USA) this happened in many countries. Currently the body which is responsible for monitoring nuclear arsenals is called the IAEA (Internationl Atomic Energy Agency)
What did America do during World War 2 that no other country did?
The only actions of consequence would be the 2 Atomic Bombs dropped on Hiroshima and Nagasaki in 1945. The USA are also the only country ever to use a Nuclear device against an Enemy country.
How are hydrogen bombs set off?
A small nuclear trigger (the primary) inside the weapon is exploded and used to generate energy, which is used to compress another device (the secondary) inside the weapon. This energy causes the secondary to collapse on itself, initiating a fusion reaction in the fusion fuel (Lithium6 Deuteride) contained in the secondary.
Which country exploded 1st underground nuclear device?
every country that has done underground nuclear testing at some point exploded their first underground nuclear device. if you want the first country, that was the US. if you want the most recent, that was North Korea. but this could change any day.
Which country exploded first its nuclear device?

Which country exploded its first under ground nuclear device?
U.s
Asian nation that exploded its first nuclear device in 1974?
India
Which country first exploded underground nuclear device?
US, but it was not underground to contain the effects. The Buster-Jangle Uncle shot was a 1.2KTon shot at 17 feet underground. The purpose was to study cratering effects. Data from this shot was then scaled up to predict the effects of the MK-8 and MK-11 ground penetrator atomic bombs, which had a yield of 15 to 20 KTons.
Which country explore 1st underground nuclear device?
I believe the first underground nuclear test explosion was done by the US at the Nevada Test Site. However it was not intended to contain the blast or radiation. It was an effects shot to evaluate cratering, the bomb was only 3 feet underground. It was part of the 1955 Teapot series.
Which country is the first to use nuclear device?

What happened on September 2 1949 that changed the nature of the cold war?
The Soviets got the "bomb" in '49 (they exploded their first nuclear device). Now, the US & USSR had the same weapon. Red China would be next. Then there would be three.
