Report containing "flight data and (...) results of radiochemical analyses of stratospheric and tropospheric air filter samples collected during Project Star Dust. This report contains data for samples collected during June 1961 to December 1962, the first year and a half of the project" (p. 2).

From abstract: "A scintillation detector has a pulse height output which is a linear function of the energy of impinging gamma radiation. A pulse height analyzer system determines the amplitude distribution of this train of pulses. The system also displays this information graphically in a form which is convenient for further analysis."

Abstract: A control system to provide digital printing and to plot an analog trace on an electric operated IBM model 11C Output Writer is described. The Digital mode of operation translates multidigit numbers through a set of commands to print each digit serially, then presents them to the output writer in a time sequence. The Analog mode of operation converts a d.c. input voltage to a digital number and by tab and space bar commands translates the carriage horizontally a distance proportional to this number.

Abstract: A four decade log count ratemeter based on a three diode pump section is described. The design equations for this system are included. The unit is contained in a chassis 3 1/2" high by 9 1/2" wide by 6" deep. All circuits are constructed on etched circuit boards to facilitate testing, construction, and servicing.

Abstract: "The energy absorption spectrum of cosmic ray mu mesons at sea level was inferred from the omnidirectional momentum, the latter being obtained from the directional intensities of muons in various energy intervals at zenith angles of 0, 30, 60, and 68 degrees. ...From the energy absorption spectrum, a sea level muon dose rate of 2.23 microrads per hour was determined. This is consistent with measurements of the total cosmic dose rate."
