Scientists have been building nuclear weapons for more than 80 years, but crafting this technology remains a challenge.

July 16, 1945, marked a turning point in history with the first nuclear test, named Trinity, in the New Mexico desert in the ...

The International Atomic Energy Agency (IAEA) defines uranium as a Low Specific Activity material. In its natural state, it consists of three isotopes (U-234, U-235 and U-238). Other isotopes that ...

Since the first nuclear explosion in history during the Trinity test in 1945, nuclear weapons have significantly shaped the ...

Natural isotopes of uranium are U-238, U235, and U-234 (see table above for natural abundances). Depleted uranium contains less of the isotopes U-235 and U-234. The specific activity of depleted ...

or more. There exists also a radiative capture process producing an isotope of thorium (Th 233) of 26 min. half-life; this process has a resonance character with a large contribution from thermal ...

This isotope of hydrogen is called deuterium ... In its natural state, common uranium (U-238) can't generate destructive nuclear explosions. It either must be enriched—made more concentrated ...

and the time it takes for one-half of a particular isotope to decay is its radioactive half-life. For example, about 1.5 percent of a quantity of Uranium 238 will decay to lead every 100 million ...

Uranium has two main naturally occurring isotopes - uranium-235, with 92 protons and 143 neutrons, and uranium-238, with 92 protons and 146 neutrons. Those three neutrons make a huge difference.

Igor Kirillov explained that the depleted uranium ammunition’s collision with the target produces a hot cloud of fine aerosol of the uranium-238 isotope and its oxides MOSCOW, March 24.

Different isotopes of a single chemical element are distinguished ... SRS produced the Pu-239 from a combination of uranium-235 (U-235) and U-238 in the reactors. U-235 in this “fuel” released ...

T here is a fairly popular idea circulating the Internet that a single gram of uranium contains about 20 billion calories, with some joking that eating it could sustain you like a turbo-charged diet ...
