Uses of radiation in radioactive dating

The amount of carbon-14 in the air has stayed the same for thousands of years.There is a small amount of radioactive carbon-14 in all living organisms because it enters the food chain.Neutrons are elementary particles which are emitted during certain types of nuclear reactions.Neutrons have no charge and are also highly penetrating.There are four basic types of ionizing radiation: alpha, beta, gamma and neutron.

Henri Becquerel of France discovered natural radioactivity a year later.

The approximate time since the organism died can be worked out by measuring the amount of carbon-14 left in its remains compared to the amount in living organisms.

Radiation is an extraordinarily versatile and useful tool in medicine, industry, and research.

Beta particles are electrons emitted from nucleus of atoms at nearly the speed of light.

They have a very small mass compared to protons or neutrons and carry a negative charge.
