Electromagnetic waves sources

 We are commonly using this stuff in our so called life. It is a very useful things.

 But don't you noticed that from the visible light to radio waves (middle to left) it is commonly seen on our houses and we are mostly using it daily. While from visible light to gamma rays (middle to right) it is seen on hospitals and only experts such as doctors, therapist are only the ones who's using it. Because it is harmful, just why they are using gears and other safety clothing.
