[ RadSafe ] outdoor low dose rate measurements

I just finished a calculation that's going to require a minimally trained 
individual (not a radworker)  to notice the difference between 0.03 
mrad/hr and 0.13 mrad/hr on a handheld meter while walking around an 
outdoor storage area. I'm stressing that this is a calculated result 
because it's the maximum calculated difference. The minimum calculated 
difference is between 0.02 mrad/hr to 0.04 mrad/hr. Actual dose rates 
should fall somewhere in between.

Is this a reasonable expectation, or is it asking too much of an outdoor 
walk-around with a hand held meter?  BTW, I have no idea what the radon 
conditions are.
