NEUTRON RADIATION DETECTED ON COMMERCIAL AIRPLANE FLIGHTS: Want to experience space weather? Just step on board an airplane. Flying above 30,000 feet can expose passengers to potentially significant doses of cosmic rays. We have just conducted a new survey of radiation on flights over 5 continents and, using bubble chambers, detected an abundance of deep space neutrons. Learn more about this biologically effective form of cosmic radiation on today's edition of Spaceweather.com.
