Fossil radioactive dating

Radiometric dating

There are three types of radioactive decay that can occur depending on the radioisotope involved: Alpha radiation can be stopped by paper, beta radiation can be stopped by wood, while gamma radiation is stopped by lead. Types of Radioactive Decay. Radioisotopes decay at a constant rate and the time taken for half the original radioisotope to decay is known as the half life. While radioisotope dating is the most commonly used method for dating fossils, other techniques do exist.
