Before exploring the various ways that radiation is used in and affects the world around you, it’s important to have a general understanding of what radiation is and how it works on a fundamental level.

Our understanding of radiation comes from a long history of research, involving some of the brightest minds and famous names of their times. Find out how the understanding of radiation and what it could do evolved from the discovery of a new kind of “ray” to one of the strongest power sources (and powerful weapons) known.

Outside of nature, there are areas where radiation and radioactive material might come into contact with the average person. We examine the more common of these sources, and how much they contribute to the average person’s annual exposure.

Putting to rest the myth that being exposed to radiation, such as medical X-Rays, somehow makes you radioactive yourself. We discuss the difference between radiation and radioactivity, and what makes something “contaminated.”

Learn about the differences between Alpha, Beta, Gamma, X-Ray and Neutron Radiation.

Radiation isn’t just generated in laboratories and reactors. It’s a fundamental part of the universe, and it can be found in a variety of surprising places. Discover how commonplace some sources of radiation can be, and hopefully gain some helpful context for discussing levels of radiation.

Addressing probably the most fundamental concern about radiation, how it affects the human body and health, including a primer on how to talk about levels of exposure.
