Quite true.  I have a Geiger counter, and was working on a difficult project at 
work and kept getting interrupted.  I brought my counter into work and just 
left it on my desk, clicking at the usual background radiation.  It made people 
really nervous and they pretty much left me alone.

One time, I was taking a trip to Mexico to do some shopping, and brought it 
with me, just in case there might still be some Fiesta ware out there.  TSA 
searched my luggage every single time while it was there.

As for radioactive equipment, I used to work for a firm that built monitoring 
gear for nuclear testing.  In one test, the tunnel collapsed, crushing our 
equipment enclosure.  A couple of years later, we got a call, saying our gear 
had been excavated, but it was full of probably-radioactive dust and partly 
crushed, asking if we still wanted it.  We declined, but I assume some gear 
like that surfaces at equipment auctions occasionally.  Maybe I should bring my 
counter to hamfests?

I had a pet that was treated with iodine-131 for hyperthyroidism once.  I was 
told to discard any bedding after a week, because it would "become 
radioactive".  I-131 is a beta emitter, and beta rays (which are just 
electrons) can't make things radioactive, it takes neutrons to do that.  The 
only real dangers are excreted I-131 and, if the betas are energetic enough, 
and I use materials of high atomic weight as bedding, they could produce X rays.
