Video: Learn about the two types of radiation that surrounds us

When it comes to radiation, we often imagine big explosions or scary transformations, but that's incomplete.

Electromagnetic radiation is net energy, including electric and magnetic wave interaction.

The answer begins by understanding that radiation simultaneously describes two completely different phenomena: electromagnetic radiation and nuclear radiation.
