Or even worse ... Pu-238. With Pu-238, you don't even have the benefit of that nice 60 keV gamma / X-ray that you do with "aged" Pu-239.

You seem to be making 2 assumptions which may not be valid:

2.  ASSUMPTION:  The radioactive material of interest would create a high level  radiation field.  REALITY:  Many dangerous radioactive materials would not create a high level radiation field, for example, Pu-239.  Thus, even a low level radiation field could indicate a problem.
