Radiation and Alaska
Here in Alaska, as everywhere else, a major source of background radiation is from natural radiation such as rock formations, cosmic rays, etc. There are also some facilities that use nuclear medicines and conduct x-rays. Nuclear activity is greater in certain areas of Alaska. Many tests have been conducted in areas such as Point Hope (Project Chariot), Fort Greely, and Amchitka, where some leakage may occur.
As for outside influences, there is a very real threat from old russian nuclear reactors. Bilibino is the closest russian nuclear site to Alaska. Therefore, it is important that we not only understand radiation but to also monitor their background levels. Through monitoring, we will be alerted to any prolonged increases in background readings.
