Danger and shelter of electromagnetic radiation
Though electromagnetic radiation is ubiquitous, only after electromagnetic radiation exceed certain intensity, can produce negative effect to human body, lead to the fact headache, insomnia, memory decline and blood pressure rise or drop and heart appear demarcation line nature unusually,etc. symptom. If the long-term homework under the environment of the ultra intensity of electromagnetic radiation, perhaps the serious one causes some personnel's miscarrying, cataract, even bring out cancer.
Also epidemiology does not investigate that can prove the impact on human body of electromagnetic radiation at present. Everybody lives in the electromagnetic environment, but because everybody's individual difference and sensitivity to the electromagnetic wave are different, so the influence that leads to the fact is at various degrees. Except special crowds such as the pregnant women, equipping with the pacemaker of pregnant the first three months,etc. need especially taking some special safeguard procedures, the general crowd needn't be too anxious, only need pay attention to the general shelter.
Most radiation protection when it is simple it is in method and household appliances, office equipment, cellular telephone,etc. radioactive source last distances appropriate, don't concentrate on putting the household appliances, reduce the frequency of contact with these radioactive sources at the same time. Various household appliances, office equipment, cellular telephone,etc. should try hard to avoid operating for a long time, try hard to prevent many kinds of official working and household appliances from using at the same time at the same time. It is greatest that the mobile phone puts through the electromagnetic radiation that is released in the twinkling of an eye, should try hard to make the distance between head and mobile phone aerial a little farther while using, you had better use and separate earphone and microphone to answer a call.
Electromagnetic radiation is endangered and protected
