Above:\u00a0 Animation of a half-wave dipole<\/a>\u00a0antenna<\/a>\u00a0radiating\u00a0radio waves<\/a>, showing the\u00a0electric field<\/a>\u00a0lines. The antenna in the center is two vertical metal rods connected to a\u00a0radio transmitter<\/a>\u00a0(not shown). The transmitter applies an\u00a0alternating electric current<\/a>\u00a0to the rods, which charges them alternately\u00a0positive<\/a>\u00a0(+) and\u00a0negative<\/a>\u00a0(\u2212). Loops of electric field leave the antenna and travel away at the\u00a0speed of light<\/a>; these are the radio waves. In this animation the action is shown slowed down enormously. — from Wikipedia<\/a>.<\/p>\n

Standard Building Biology evaluation guidelines<\/a> recommend levels of exposure of <\/strong>0.0003 uW\/cm2 in the radiofrequency range, <\/strong>or 0.0030 mW\/m2\u00a0<\/strong>(unit of measurement used on this website, milliwatts per meter squared<\/strong>).<\/p>\n

The guidelines define RF radiation levels according to the expertise and experience of the Building Biology Institute, FOR SLEEPING AREAS<\/strong>, as follows:<\/p>\n

Radio frequency (RF including microwaves) safety readings in the home <\/strong>(especially in sleeping areas where we spend most of our time):<\/p>\n
