Subject: Can signals from radon gas in a sphere provide x,y,z location information?

If I placed microscopic array of sensors on the inside surface 
of an evacuated sphere and injected an amount of radon gas, 
would the signals sensed by the array be uniform when the sphere 
was at rest? (Assumption being even distribution of gas 
molecules.)And when the sphere was accelerated in any direction 
from a known starting point, wouldn't the relative inertia of 
the molecules result in a redistribution of molecules that 
produced a signal that could correlate to the speed and 
direction of travel? Thus, might not such a device serve as a 
gyroscope for use in inertial navigation? Would the gas 
molecules behave in response to motion in the way required?
