Make as many phone calls as possible using landlines which emit no radiation, and which can often be used for free and for unlimited time via the Internet, even for phone calls abroad. As you probably know, the World Health Organization issued a controversial report at the end of May saying that radiofrequency electromagnetic fields, which is to say cell phones, are possibly carcinogenic to humans based on an increased risk for glioma, a malignant type of brain cancer.
