Equivalent Dose - Video Lesson

Hey, everybody. Welcome back. This is the fourth video in a series on radiation units and measurements. This video, we're talking about equivalent dose. To understand equivalent dose, we first need to understand the limitations of absorbed dose. Here's an example. Consider two people that both received an absorbed dose of one gray. One person received that dose from x rays, and the other person keep their dose from alpha particles. So between these two people, who experienced the most biological harm? It's the same absorbed dose. So it should be the same amount of damage. Right? Wrong. These doses are not equivalent to each other. The difference in biological harm is based on differences in the linear energy transfer of the radiation types. Linear energy transfer or abbreviated LED is the rate at which radiation energy
