 cell phone jammer can prevent prisoners from making confession in collusion through the illegal communication equipment. As the production process all the different manufacturers, the market is divided into winding type lithium polymer (Sony, Toshiba, as the representative), laminated (TCL, ATL representative) two different structures, but adapted to the specifications of demand for mobile phones mostly in the 4mm thickness or less. Compared with the liquid, due to the use of a thinner polymer packaging aluminum than steel, aluminum and thinner, and different production methods with liquid lithium, the thinner the better production of polymers, in theory, can produce the following 0.5mm thickness of the battery. Liquid lithium on the contrary, the thicker the better production, less than 4mm thickness of the battery is difficult to produce, even if produced, significantly less capacity polymer lithium battery, did not cost advantages. Thus, the battery is thinner, lower polymer production costs, higher production costs of liquid. However, the specifications of the thick liquid lithium supply chain mature, mature technology, high efficiency, high yield, has a strong manufacturing cost advantage. Then, the electromagnetic radiation on the human body mechanism is like? According to common sense, the human body is a conductor, we can absorb electromagnetic energy. The role of the electromagnetic field, the orientation of the body's molecular arrangement occurs in the molecular arrangement of the magnetic field during the collision energy consumed is transformed into internal energy, causing thermal effects. Electromagnetic field strength is larger, the thermal effect is more obvious; the higher the frequency of electromagnetic vibration, thermal effects, the more obvious. Scientific experiments have shown that electromagnetic radiation pollution on the health hazards are mainly two aspects - the role of induced thermal effects and non-pyrogenic. Thermal effect is caused by electromagnetic waves penetrate the surface of the organism, the body directly to the internal organization of the "heat" (the same as the microwave heating of food), that the role of high-frequency electromagnetic waves, the material will change the temperature, high-frequency electromagnetic waves caused by heat will have an impact on the role of organisms, which cause serious harm to humans, leading to breast cancer, impotence, miscarriage, fetal malformation and other diseases. Is the nonthermal effects of electromagnetic waves on human autonomic nervous system damage, resulting in heart palpitations, hair loss, bradycardia, hypotension and women's menstrual disorders and other diseases. Now that you understand the principles and hazards of electromagnetic radiation, how to do that in life preventive measures? China Interior Decoration Association Indoor Environment Test Center experts to draw attention to the following: For the indoor environment in office equipment, home appliances and mobile phones caused electromagnetic radiation hazards, people should take the following protective measures.
