In light of the looming threat of radioactive contamination coming across the Pacific from Japan I thought I would post this live radiation monitoring site in West LA.
You can see what the radiation level is there in real time for those that would like to keep up to date on what the current level is.
The number represents radiation Counts per Minute, abbreviated CPM, and under normal conditions, quantify the level of background radiation, i.e. environmental radiation from outer space as well as from the earth's crust and air. Depending on your location within the US, your elevation or altitude, this background radiation level might average anywhere from 5 to 60 CPM, and while background radiation levels are random, it would be unusual for those levels to exceed 100 CPM.
