how many rems is the maximum this device will detect? 6rems a day and no problems according to cdc, so hopefully it goes to 20rem.

The sensitivity and working range are a function of the Geiger tube that is used with the kit. The included SBM-20 has a working range of 0.014 - 144 mR/hr according to http://www.gstube.com/data/2398/
