does television radiation go through walls ?

Question

i'm talking about the x-rays from tv (duh) :)

Answer 1

The X-rays do pass through the walls but the intensity of the radiation is nothing to be concerned about. As the radiation travels further from the TV the electric field strength falls off with an inverse-square relationship to the distance from the TV. This means that the intensity of the electric field becomes extremely weak very quickly. Some X-ray radiation will be absorbed but, remember, X-rays must be absorbed by the inner-electron core of the atoms (or even the nucleus in some cases) and as this is a very small volume compared to the volume of 'empty' space in a crystal structure it is unlikely much will be absorbed. Especially in a gas (gasses wil absorb the x-ray radiation even less because the atomic density is less)!

Metals stop x-rays because, whilst they display a positive relative permeability (magnetic) they display a negative relative permittivity (electric) and so electromagnetic radiation is attenuated exponentially. Constant exposure to x-ray radiation from a TV up close might be hazardous because we have sufficient metal in our bodies to cause the absorption of radiation to ionize the molecules of the proteins that make up our DNA.

The concise answer to your question is 'yes, radiation from televisions does go through walls as long as the metal content of the walls is sufficiently low and the walls sufficiently thin (which they usually are).

Answer 2

The x-rays (what few there) are pretty muchabsorbed by the air an inch or two in front of the screen

Answer 3

Note that flat screen TV's (LCD and plasma) do not generate x-rays.

Answer 4

i think it is so near to t.v so it cannot go through walls
