Fermilab - A different perspective on radiation types from a very famous source.  Fermilab is a world leader in this type of research, funded by the US Department of Energy.  They cover the same types of radiation as the video above along with some information about EM radiation, or light.

 TedED - Is radiation dangerous.  Sometimes yes, but usually no!  Here you will get some details about the different dangers associated with radiation exposure.

US DOE - A brief training video for first responders when dealing with radiation disasters produced by the US Department of Energy.  It discusses different types of ionizing radiation: the dangerous kind!

Vertasium  - A great video that talks about background radiation, or the radiation we experience everyday.  Background radiation is compared at many sites around the world, including sites of radiological disasters such as Hiroshima, Fukushima, and Chernobyl.  They clearly have a larger production budget than I do!  It even has a quick PSA at the end about why smoking cigarettes is still a bad idea!

Let's Talk Science - Very comprehensive overview of the different radiation types, clear description of the differences of ionizing vs. non-ionizing radiation, as well as a little about EM radiation, or light.

Health Physics Society - This article focuses on the health impacts of different types of radiation exposure.  Each radiation type affects the body in different ways and to different degrees, all of which is outlined here.

Canadian Nuclear Safety Commission - A rundown of different types of radiation, including ionizing and non-ionizing types.  This site was created for consumer use, and is written to be easily understood by the general population.  It focuses on the dangers and likelihood of exposure of different radiation types.
