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.
In and of itself, what is so dangerous about EXTERNAL exposure to Pu-239? It's not very radioactive. The danger (problem, whatever) is that enough would be sequestered to produce a criticality.
Other that the danger of criticality with fissile materials, what is dangerous about external exposure to radioactive materials that have a low specific activity?
