Cell phones.........???


There are several different types of radiation present in our surroundings on a day to day. Electromagnetic energy from cell phones and radio towers are categorized as non-ionizing radiation and are generally thought to be harmless, while iodizing rays from x-rays and nuclear energy has been proven to cause cancer. However, in recent years the sheer number of non-ionizing instruments in our environment has caused some scientists to wonder if the assumption that this type of radiation is truly safe at low levels as once thought. As cell phones, microwaves, satellites and radio have all become much more widespread; people claim to suffer everything from headaches to cancer as a result of their exposure to this "harmless" radiation
