Note: Geiger Counter is bugged ( http://fonline2238.net/forum/index.php/topic,22879.msg189646.html ) now and does not work.
With a Geiger Counter in your inventory and powered on, you will get constant notifications of your radiation level until you either power off the unit or it expends it's charge. The notifications appear in your message box every so many seconds. Alternatively, you can place one on the ground and it will serve this same function for multiple characters who are standing close enough.
