How does radioactive dating occur

Alpha decay The atom releases a helium atom (2 protons, 2 neutrons) Beta decay A proton turns into a neutron or vise versa, emitting a particle like the electron during the process.

There are many more types of decay but these two are prominent examples.

Usually the particles that are emitted during radioactive decay are small, maybe only one proton.

However this can do serious damage if it comes in to contact with DNA, it can rearrange the structure and cause all kinds of mutations in your genetic code.

So, if you know the radioactive isotope found in a substance and the isotope's half-life, you can calculate the age of the substance. Well, a simple explanation is that it is the time required for a quantity to fall to half of its starting value.

So, you might say that the 'full-life' of a radioactive isotope ends when it has given off all of its radiation and reaches a point of being non-radioactive.

When a creature dies, it ceases to consume more radiocarbon while the C-14 already in its body continues to decay back into nitrogen.

Radioactive dating is a method of dating rocks and minerals using radioactive isotopes.Radiometric dating, or radioactive dating as it is sometimes called, is a method used to date rocks and other objects based on the known decay rate of radioactive isotopes.Different methods of radiometric dating can be used to estimate the age of a variety of natural and even man-made materials.The new isotope is called "radiocarbon" because it is radioactive, though it is not dangerous.It is naturally unstable and so it will spontaneously decay back into N-14 after a period of time.The methods work because radioactive elements are unstable, and they are always trying to move to a more stable state. This process by which an unstable atomic nucleus loses energy by releasing radiation is called radioactive decay.
