Radioisotope contamination swab

Summary:

Which materials are best to use for swabs/swipes to check for contamination?
I was wondering if it was possible to use a simple cotton swab (like those you might buy at the pharmacy) and some ethanol to do a wipe test to check for radioactive contaminants? It's to wipe test an object in my home, would that be sufficient?

If you aren't looking for really precise results, it should be fine. You'll definitely want to do a blank/background (what's the radioactivity of a swab w/ethanol by itself). Professionals also usually have some known radioactive standard against which to calibrate their results, but unless you know what you're doing, I wouldn't mess around with stuff like that.
