Q:The foil or foil can be isolated (or reduced) computer radiation:

4, in the diet to pay attention to the role of radiation resistance of food, such as cruciferous vegetables, rape, vegetables, mustard, cabbage, radish and so on, have anti radiation function. Black sesame to enhance the humoral immune function, cellular immunity, can effectively protect human health; purple amaranth can resist radiation, anti mutation, antioxidant; tea polyphenols Green Tea in anti radiation material, can reduce the radiation of various adverse effects on the human body, the tea also contains lipopolysaccharide, can improve hematopoiesis function, elevated platelet and white blood; fresh fruits and vegetables rich in vitamin A, B, C, and E, the impact of these foods rich in vitamins can reduce the electromagnetic radiation on the human body.5, in the computer table near a pot of plants or water, you can absorb the electromagnetic wave emitted by the computer. Radiation: the best plant cactus or cactus can absorb electromagnetic radiation and reduce the harm to human health computer's "special features", cactus thorn body thick meat, containing water, easy to absorb and dissolve the electromagnetic radiation poisoning of the surrounding environment, reduce indoor pollution, beneficial to human health.

Q:Aluminum foil heat transfer of heat insulation is how, orThe old radiator looked black and looked uncomfortableA friend suggested wrapped with aluminum foil, has good heat dissipationOn the radiator, aluminum foil feel hot, not hot outHope to get your bachelor's scientific explanationThe foil blocking heat radiationThat is to say, tinfoil radiators (in the case of no gap) will affect the heat, huh
