WebGeothermal energy comes from deep inside the earth. The slow decay of radioactive particles in the earth's core, a process that happens in all rocks, produces geothermal … WebBecause radioactive decay is a first-order process, radioactive isotopes have constant half-lives. Half-life is symbolized by t1/2, and it's the time required for 1/2 of a sample of a particular radioactive isotope to decay. For example, the half-life of Strontium-90 is equal to 28.8 years. Let's say we start with 10 grams of our Strontium-90 ...
