Can aluminum plate protect against radiation?
Two. A brief introduction to radiation:Radiation refers to electromagnetic energy from the source part from the field source and transmitted, then return to the source, energy by electromagnetic waves or particles (such as the Alfa particle, beta particle) in the form of outward diffusion. All objects in nature, as long as the temperature is above zero degrees of absolute temperature, send the heat continuously in the form of electromagnetic waves and particles. This way of transmitting energy is called radiation. The radiation energy radiates straight from the source outward in all directions. The energy emitted by an object through radiation is called radiant energy. The radiation was calculated by roentgen / hour (R). One important feature of radiation is that it is "peer"". A body can radiate radiation to a second object, and at the same time a radiation to a target, regardless of the temperature of the object (gas). The term is commonly used in ionizing radiation. Radiation itself is a neutral term, but radiation from certain substances can be harmful.
First, the installation depends on the way, the direct aluminum plate can not, the aluminum plate must be grounded in order to play a role. The ground is connected with the earth plate, this shot to the electromagnetic wave on the aluminum plate will be aluminum absorption into electrical energy and flow to the ground, if not grounded on the other side will generate an electric field in aluminum, is directly through to the. In fact, grounding is very simple, if the installation of the use of metal screws directly contact the aluminum plate, but also with the cement wall contact, you can be grounded, although not good grounding. If the wall is a wooden board and so on, the insulating material can not, and then there is a screw, if it is used in the wall dug into the plastic sleeve also can not, because the plastic will be insulated.
It can only about radiation, and other materials have not heard of this performance.
