For the electromagnetic spectrum the only bands that conventional walls are opaque to are infrared, visible, and ultraviolet light. If the walls have lots of metal in them then they may also be opaque to parts or all of the radio wave and microwave bands.
For particulate radiation the walls will be opaque to all charged particles, unless they are at very high energy (e.g. cosmic rays).
Several types of electromagnetic radiation can penetrate the wall of a house.
The thick walls around it
All the walls are black because of the smoke off the fire! Hope this helps you! Sophie
A contractor build two houses with 2 by 6 walls. He sprayed 1.5 inches of foam into the walls of one house and used standard fiberglass insulation for the other house. The house with polyurethane insulation always had lower electric bills. They believe this is do to the fact that the foam is the worlds best insulation and it seals all air leaks.
through the insulted walls, door when it is open,and warm food placed in the refrigerator
The front door to your house because it determines what comes in and out of the house.

UVR is not able to penetrate opaque surfaces like walls, however, certain surfaces such as glass may allow UV radiation to penetrate depending on how the glass has been treated. Water allows UV to pass through but only to a certain depth where it will get absorbed in within the water molecules.
Heat leaves your house through the roof, floors, walls, doors and windows by means of draughts, radiation and conduction.
Photographs can't... infrared is a possibility.
Yes, probably.
probably smoke, or you aren't washing them as often as you need to my mom washes the walls 2 times a week to keep the house really fresh...or you house might be really old...who knows.
Allows it to penetrate more walls, and does a little more damage
Your house might be warm on a cold day because inside the walls there might be something to insulate or keep all the wamth from going away.
alpha radiation is more dangerous than beta or gamma if ingested or inhaled because its power to ionize (or to disrupt atoms) is 20x than that of beta and gamma. but if the source is outside the body or at a distance gamma radiation is much dangerous because it could penetrate thick walls.
Heat energy travels in three ways: convection, radiation, and conduction. The radiation from the sun heats the air around the house, making the walls warm. Than, the walls warm up the air inside the house. The sun rays go through the windows, which will trap heat. The heated air will rise, and stay there unless there is an escape route for it.
