Recommended Sigma values:
Sigma = 6 enables almost false alarm free searching in areas with
a fairly constant radiation background.
For general use, especially in an urban environment the setting of
a minimum count rate for the Alarm 1 via the PC-configuration
program is recommended to avoid false alarms from certain natu-
ral materials. Frequently paving stone and plates made from gran-
ite contain substantial traces of Uranium and Thorium.
