^{4}\textrm{He}\) When a radioactive atom emits an alpha particle the mass number decreases by four and the atomic number drops by two. Here is the equation for the alpha decay of radon-219 into ...

The table below shows the fraction by weight of the three isotopes in any quantity of natural uranium, their half lives, and specific activity. The half life of a radioactive isotope is the time taken ...

But, in the spirit of rebranding, it is interesting to note that the main source of Earth's internal heat comes from the radioactive decay of uranium, thorium and potassium-40 that keeps the outer ...

However as the number of protons increases, more neutrons are needed to keep the nucleus stable, for example lead, lead-206 has 82 protons and has 124 neutrons.

As another plus, this carbon-14 is derived from graphite blocks, which are a byproduct of nuclear fission reactors. So, not ...

More than 400 inmates were removed from the prison after the discovery of high levels of radon – a colourless, odourless ...

Uranium is a radioactive element, meaning its atoms are unstable and decay over time, emitting ionizing radiation. This radiation can damage living tissues and DNA, leading to radiation sickness ...
