What Happens If You Get Bitten by a Radioactive Spider?

Not much. Or rather, not much aside from the usual symptoms of being fanged by an arachnid: itching, redness, soreness, and sometimes?depending on the type of spider?more serious symptoms, including unconsciousness or death. The radioactivity, though, would be irrelevant. The world is awash in radiation. We?re exposed to about 3 millisieverts of it a year, mostly from the sun and naturally occurring radioactive gases like radon. That?s not counting doses from medical procedures such as CT scans (6 mSv), mammograms (.4 mSv), or X-rays (.1 mSv); from airline travel (.01 mSv); or from smoking (53 mSv per year). The amount of radiation contained in the venom from a single spider bite would likely fall between .00003 and .000003 mSv?an inconsequential dose, about as much radiation as you?d absorb from eating a banana, which contains the radioactive isotope Potassium-40.
