Antique radiation

After the excitement over the Fukushima nuclear plant, people in Japan are (understandably) a little jumpy about radiation. This seems to have led to the discovery of a bunch of antique radiation sources. A recent radiological survey of the Puget Sound area was done to establish what the normal baseline radiation level is (because the similar surveys in Fukushima had not had a pre-reactor-problem level to compare to). They were expecting to find a lot of non-disaster related radiation, and I wonder if they found any old bottles of radium, too?
