RADIATION MEASUREMENTS WITH BALLOONS, 1961

Technical Report ·
OSTI ID:4740429
A group of radiation detectors for monitoring solarflare radiation in the upper atmosphere was prepared and flown on a series of balloon flights to altitudes of about 125,000 ft at Bemidji, Minnesota, during the summer of 1961. The instruments consisted of a scintillation telescope, two neutron detectors, and a shielded Geigercounter monitor. The neutron counting rates observed in both neutron detectors as a function of altitude are compared for all flights. The neutron counting rates observed on a day of normal activity are compared with the neutron fluxes calculated assuming a source of neutrons produced only by primary cosmic rays interacting in the atmosphere.
