Although the radioactive decay of a nucleus is too small to see with the naked eye, we can indirectly view radioactive decay in an environment called a cloud chamber.

This “tagged” compound, or radiotracer, is then put into the patient (injected via IV or breathed in as a gas), and how it is used by the tissue reveals how that organ or other area of the body functions. A PET scanner (a) uses radiation to provide an image of how part of a patient’s body functions.

We classify different types of radioactive decay by the radiation produced. Alpha particles, which are attracted to the negative plate and deflected by a relatively small amount, must be positively charged and relatively massive.

Beta particles, which are attracted to the positive plate and deflected a relatively large amount, must be negatively charged and relatively light.

Ernest Rutherford’s experiments involving the interaction of radiation with a magnetic or electric field (Figure 2) helped him determine that one type of radiation consisted of positively charged and relatively massive α particles; a second type was made up of negatively charged and much less massive β particles; and a third was uncharged electromagnetic waves, γ rays.

We now know that α particles are high-energy helium nuclei, β particles are high-energy electrons, and γ radiation compose high-energy electromagnetic radiation.
