I guess it's one of those things where the intensity of the radiation is proportional to 1/d^2.
If you're holding it in your hand it emits enough radiation to be very unhealthy, but as soon as you put some distance between you and it then it becomes very hard to detect.

Cs-137 has a clear gamma emmision spectrum (which is to say it glows a unique color of high-energy photons), so you can scan and pick it up with a scintillation detector. Unfortunately, Cs-137 is one of the bits of waste generated as fallout from nuclear testing, and its half-life is 30 years, so ambient levels are generally not identically zero.
