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/.
