Testing For Radioactivity

Why Test For Radioactivity?

Radioactivity constitutes potential harm to humans and the environment because of its ability to interact with and change matter. Its radiation is “ionizing” which means that it has enough energy to remove electrons from atoms or molecules when it passes through or collides with some material. The regulation of radioactivity falls under the authority of the US Environmental Protection Agency and the US Nuclear Regulatory Commission.

Where Does Radioactivity Come From?

Radioactivity is everywhere and originates from three primary sources. NATURALLY OCCURRING RADIOACTIVE MATERIAL has been present since the creation of the planet and is found in air, water and throughout the earth’s crust. ANTHROPOGENIC, or man-made radioactivity, originates from nuclear reactors, fallout from nuclear weapons testing, nuclear accelerators and the manufacture of isotopes used for medical purposes. COSMOGENIC radioactivity is caused when cosmic rays strike the earth, inducing radioactivity in the atmosphere.

How Do We Test for Radioactivity?

Radioactivity is measured by detecting the atomic disintegrations that occur in a sample and counting the number of these events that occur during a specific time period. Scientific instruments employ one of five basic technologies – High Purity Germanium Crystal detection, Liquid Scintillation Counting, Alpha Scintillation Counting, Alpha Spectroscopy and Gas Flow Proportional Counting. Prior to detection, specific isotopes are often isolated from the sample matrix by means of chemical separations.
