In my experience, depending on all the variables you mentioned, it could be
anywhere from 30 seconds to 20 minutes or more.

What are typical exposure times for field radiography (like an Ir-192
camera)?  Yes, I know it depends on the source strength, item under test,
etc., I'm just looking for ballpark times (like 1 min, 5 min, 10 min).
