Concern/Watch and Alert Sites 

Each radiation monitoring site has an RBL value set by software, which is the Radiation Background Level.  RADCON-1 = R.B.L., RADCON-2 = Rising, RADCON-3 = Elevated, RADCON-4 = Concern/Watch, RADCON-5 = RAM email sent.   When the level exceeds the RADCON-4 Concern/Watch level on the chart, other conditions must be met to trigger a RADCON-5 RAM (Radiation Alert Message) email or text message to your phone.  Our software uses statistical analyses to generate these alerts.  

Do Not Panic, always check with other reliable sources. Please read the disclaimer below **
