To better understand how radiometric dating helps us determine the age of rocks, it will help us to gain a better understanding of how elements decay.

Radioactive decay is the term used for the process by which an unstable atomic nucleus loses energy by releasing radiation.

But essentially, what is happening with beta decay is that we are taking a neutron, removing a negative charge and turning it into a proton.

Gamma rays can travel through your body but not through lead.

Plus, get practice tests, quizzes, and personalized coaching to help you succeed. So we have to rely on something called radiometric dating to figure out the age of rock.

Try it risk-free Radiometric dating is a method used to determine the age of rocks and other materials based on the rate of radioactive decay. Radiometric dating is a method used to date rocks based on the known decay rate of radioactive isotopes. Now, they do not give off enough radiation that you have to be afraid to pick them up, but they do contain naturally occurring radioactive elements like uranium, for example.
