The geiger counter in our office is similar to this unit: Craigset.
The units are micro sieverts per hour. See here for an explanation of sieverts: http://en.wikipedia.org/wiki/Sievert.
Kalin Kozhuharov has another counter down the road in Mita. You can check results from his counter here: http://thinrope.net/gamma/.
We have also connected the output to an IVR (interactive voice response) system so people can call in to get the latest readings. The system can be reached at the following numbers:
