The EPA has deployed portable radiation monitors to several locations including Guam, Hawaii, and Alaska. Below, there is a graph of the readings from the monitor located in Dutch Harbor, Alaska. The Alaskan location is in the Aleutians west of the Alaskan mainland. This location was probably selected because the jet stream often carries weather systems from Asia to the West Coast of the USA via the Aleutians.
