Radiometric Dating. Mathematical calculation of radiometric dating involves the use of a simple. for the radioactive decay of 40 K is λ = 5.543 x 10-10.We’ll also see how carbon dating can be used to date ancient. Using half-life in simple calculations. We can use radioactive decay to calculate the age of.Tritium/ 3 He dating 1. General background. Tritium (3 H or T) is the radioactive isotope of hydrogen that decays with a half life of 12.43 years to its stable daughter 3 He. Tritium is produced naturally in the upper atmosphere by interaction of nitrogen, and, to a lesser extent, oxygen with cosmic.

Radiometric dating is used to estimate the age of rocks and other objects based on the fixed decay rate of radioactive isotopes. Learn about.
