U.S. Nuclear Regulatory Commission
In response to nuclear emergencies, the NRC works with other U.S. agencies to monitor radioactive releases and predict their path. As of March 16, all the available information continues to indicate Hawaii, Alaska, the U.S. Territories and the U.S. West Coast are not expected to experience any harmful levels of radioactivity.

FAQs re: Japan nuclear emergency from EPA
Winds can carry radiation. But according to scientists, the explosions and leaks in Japan have stayed in the lower levels of the atmosphere. Radiation has not reached the jet stream, a fast moving river of air that usually runs between 20,000 and 40,000 feet in the atmosphere. Over the next week, National Weather Service meteorologists in Honolulu forecast the jet stream will remain away from Hawaii.
