WHO's warning

June 18, WHO published an environmental health standard about electromagnetic wave. According to it, the children who live in over 0.3-0.4 micro-tesla magnetic field have higher risk of suffering leukaemia than the children who live in low magnetic feild. So WHO recommended countries taking precaution. I have heard that cellular phone and microwave oven have electromagnetic wave and those are not good for our body. There are maybe many electronic instruments which have it, so we have to know about that and use them wisely.
