Can aluminum plate prevent radiation?
Probably only the lead plate to radiation, did not hear that there are other materials have this performance.
Radiation refers to the source of electromagnetic energy from the source part of the distance from the source to the distant transmission, and then return to the field of the phenomenon of energy to electromagnetic waves or particles (such as alpha particles, beta particles, etc.) in the form of outward diffusion. All the objects in nature, as long as the temperature above the absolute temperature of zero, are in the form of electromagnetic waves and particles kept out of time to send heat, this way of transmitting energy is called radiation. The energy of the radiation is radiated straight from all directions of the radiation source. The energy emitted by an object through radiation is called radiant energy. Radiation is calculated according to Roentgen / Hour (R). Radiation has an important feature that it is "reciprocal". Regardless of the object (gas) temperature are high and low radiation, a body can be radiation to the B object, while B can also be a radiation. The term is commonly used in ionizing radiation. The radiation itself is a neutral word, but the radiation of some substances may cause harm.
Depends on the installation method, not directly put aluminum, aluminum can also be a role in the ground. Grounding is to connect the aluminum plate with the earth, so that the electromagnetic waves on the aluminum plate will be absorbed into the power of aluminum and flow to the ground, if not ground will produce the other side of the aluminum field, is tantamount to go through. In fact, grounding is very simple, if the installation of metal screws directly with the aluminum contact, but also with the cement wall contact can be considered ground, although not a good grounding. If the wall is wood or the like insulation material can not, then there is a screw, if it is the kind of hole in the wall into the plastic sleeve is not enough, because the plastic insulation.
