Time for a science and math review
I write in regard to the manufactured controversy surrounding BC Hydro’s smart meter program as discussed in Quick Peaks on October 5 [“Delegates oppose smart meters”].
Opponents of smart meters are spreading some hysteria about radiation exposure from the meters. I suspect none of these people have taken a basic electricity and magnetism physics course. Let’s consider some facts:
(1) Radio frequency (RF) radiation is non-ionizing due to its low frequency and low energy, which means is does not interact with tissue the same way that, for example, X-rays and gamma rays do.
(2) The power output from smart meters is extremely low—about one watt. For comparison, the cell phone that you hold next to your head can spike up to double that depending on the model. The walkie-talkie you use at work can go up to five watts (albeit at a different frequency). Don’t get me started on your microwave.
(3) Exposure drops off by a factor of the inverse square of the distance. That means that exposure drops dramatically as you move away from the meter. Accordingly, your cell phone will cause you orders of magnitude more exposure than a smart meter.
Truly, this issue demonstrates the need for basic science and mathematical literacy among the general population. Anyone with a basic understanding of physics can easily identify the antimeter claims as bogus. Instead, we’re trying to shut down a legitimately useful service designed to save energy.
