Understanding Radiation: Half Life

In a previous installment?we learned what isotopes are, and that the decay of radioisotopes is what produces radiation. Let’s continue with our carbon example. Remember that carbon, like many elements, has a number of isotopes with different numbers of neutrons.

Understanding Radiation: Atoms and Isotopes

Let’s start at the beginning, with atoms. We probably all have a rough idea of what an atom looks like. The center, or?nucleus, is made up of pieces called?protons?and?neutrons, and this is surrounded by a cloud of electrons. Protons have
