Is TV radiation dangerous to your health?

First of all, "radiation" is any energy that flows out from a source. There is radiation coming from your body if it is cool out: This type is called, "Heat".

There is another type of radiation coming from a candle: you can see it, and it is called, "Light".

X-ray machines radiate, well, 'X-rays'.

There is electrostatic radiation coming out of older TV sets: It's the same thing as when you touch something and get a little shock. It is not dangerous.

Atomic radiation, or nuclear radiation comes from radio-active sources like uranium and radium. This one is more dangerous than the others because it is usually very strong and can 'cook' you quickly, much like a microwave oven can cook flesh.
