Federal agencies are beefing up their radiation-monitoring capabilities at home and abroad, even as they insist that significant amounts of fallout won’t waft from Japan onto U.S. territory.

At home, the Environmental Protection Agency said it's adding seven monitors in Alaska, Hawaii and Guam to its RadNet radiation-tracking system, which operates about 100 air-sniffing stations nationwide. Putting in those extra stations "allows us to gather data from a position closer to Japan," EPA said in an online question-and-answer guide.

Looking beyond America's borders, the U.S. Air Force is sending out a high-tech aircraft to sniff the air over Japan for radiation. The Nuclear Regulatory Commission and the Department of Energy's National Nuclear Security Administration are also sending experts to Japan to help counter the growing crisis at Japan's Fukushima Dai-ichi nuclear plant complex.

The NRC and the NNSA have teams who track how hazardous materials spread through the atmosphere, based on computer modeling and other methods. It was the NRC's revised analysis that led to today's advisory telling Americans to evacuate the area within 50 miles (80 kilometers) of the Fukushima reactors, or stay indoors if they can't get out of the area.
