Given the Inverse-square law, your phone and wifi network will probably give you more radiation..

I had some bones scans (plus a couple of CTs the same day, just a bit more ionising radiation) last year. They inject you with Technician 99m and YOU become the gamma/ x-ray source. It's a little concerning when you see the detail and spread of the radiation. If it wasn't a pure Gamma source (and 6hour half-life) it would be lethal!

I forget if it was 70,000 milli or microsieverts (think it was milli? 0.5% increased risk of cancer in my lifetime). Oh, and my bladder looked like a lightbulb.
