Even the extremely low frequencies (ELF) that are widely used in powerlines and domestic appliances should be viewed with caution. In June 2007, the World Health Organization (WHO) pointed out that they are believe d t o b e one of the causes for children’s leukemia. Pulsed or amplitudemodulated, at a biologically active lower frequency (i.e. when the radio signal strength rises and falls in time with the lower frequency), high frequencies are the hallmark of mobile phones, WiFi systems, PDAs, etc. At radiofrequencies, electric and magnetic fields are closely interrelated and we typically measure their levels as power densities in Watts per square metre (W/m2).
