So, I bought ~200lbs of thick lead plates off a scrapper guy on craigslist. The plates came from an x-ray machine he tore apart at a medical school. I would like to verify they are not "hot" before I do anything with them. Does anyone have a geiger counter, and would like to swing by to check em out? I'll buy ya a pint... :)

Mine are all 600+ miles away, but I know a guy. I'll check in with him. Bear in mind that a really good contamination check usually includes going over the item with a mica window "pancake" probe. Let's see what I can rustle up.

PS: If it was just from an x-ray machine and they never worked with radioisotopes, it's unlikely to have gotten "hot". But no problem playing it safe(r).

I know it was back in March, but if you still want a "sanity check" I've got a small handheld unit now. I've got the parts for a "pancake" unit that would be more suited to detecting low levels but I haven't built them up yet.

I ended up getting a real good deal on a handheld one on ebay. Thanks for the offer though :)
