Types of radioactive decay dating
The atomic nucleus which is in the center of the atom is buffered by surrounding electrons and external conditions.
For a given element, the decay or disintegration rate is proportional to the number of atoms and the activity measured in terms of atoms per unit time.For further information about different types of decay that Uranium goes through, refer to Decay Pathways).Due to the smaller size of the nucleus compared to the atom and the enormity of electromagnetic forces, it is impossible to predict radioactive decay.The unstable nucleus then releases radiation in order to gain stability.
For example, the stable element Beryllium usually contains 4 protons and 5 neutrons in its nucleus (this is not considered a very large difference).Since the decay rate is constant, one can use the radioactive decay law and the half-life formula to find the age of organic material, which is known as radioactive dating.
