Portland, Oregon US Radiation From the Facebook page Portland, Oregon Radiation, freely accessible to all. 25 CPM, 11:02 pm, December 2 to 10:53 am, December 3, 2013. Highest spike to 44. 25 CPM is the usual average these days. One person measured an average before Fukushima of 8 CPM. Individual spikes could be caused by the sun, and probably do not pose a serious threat. Sustained high averages are cause for concern. I am unable to post the graph. Inspector Radiation Alert Geiger counter, with a pancake tube. 230 feet above sea level; indoors. Folks, I am stretched very, very thin and cannot answer questions about this. I wish that you all find answers to all your questions. Be safe. Be well.
