Radiation Survey, Columbia University, Van De Graaff

Description: Abstract: During March 1958, representatives of the health and Safety Laboratory, New York Operations Office, visited Columbia University to make stray radiation measurement at the Van de Graff accelerator. A radiation survey was performed at the Van de Graaff electrostatic generator at Columbia University. The survey results do not indicate a particular need for additional shielding at this time. It is recommended that the analyzer area of the beam room should not be occupied during beam ope… more

The Sequential Analysis of Ten Nuclides Occurring in Long Range Fallout Debris

Description: Abstract : Methods for the chemical separation of strontium, barium, cesium, cerium, yttrium, zirconium, niobium, and tungsten from complex matrices are described. Procedures for the radiometric determination of the longer-lived isotopes of these elements are outlined. Inert carriers are added and the sample is dissolved by fusion with sodium carbonate. The melt is leached first with water and then with hydrochloric acid. The elements are recovered from these fractions by a series of wet chemic… more

Low Background Nuclear Counting Equipment

Description: Abstract: Both direct and coincidence counting apparatus are described. The elimination of cosmic ray events by coincidence plus gamma ray shielding permits the reduction of counting rates far beyond that obtainable with shielding alone. By selection of materials and development of new components and techniques, the residual background count of beta counting equipment can be reduced to a very low value. Geiger counter equipment for routine laboratory measurements is described, have a backgr… more

Analog and Digital Readout on an IBM Output Writer

Description: 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 proportion… more

The Significance of Urine Uranium Excretion Data

Description: Abstract: Urine uranium excretion data for persons exposed to uranium by inhalation are analyzed Data from both chronic and single massive exposures are included, and a generalized excretion pattern, applicable to any uranium compound absorbed by inhalation, is proposed. ...It is shown that it is not usually practical to use urine samples to monitor individual exposures. Such an evaluation is possible only with a suitable series of samples collected at known intervals past the exposure. It … more

The Calculation of Some Bessel Functions for Criticality Problems

Description: Abstract: An easy to use method for evaluating Bessel functions is given. This method is applicable to the one-dimensional, 2-group, 2-region diffusion problem, and is designed primarily for use on a small or medium sized digital computer. ...FORTRAN programs based on this method are presented together with the output obtained from an IBM-1620 digital computer.

Filters to Provide Nearly Monoenergetic X-Rays

Description: Abstract: Four filters for use with a 250 KVP pulsating X-ray machine were constructed to calibrate radiation detection instruments in the energy region below 200 KEV. Approximately monoenergetic beams of 63, 105, 150, and 180 KEV were produced. The spectral distribution was computer suing the formula of Kulenkampff. The energies were found to drop rapidly from the peak values. The average values were checked from absorption curves obtained experimentally and found to deviate from the computed … more

Energy Absorption Spectrum in Air of Cosmic Ray Mu Mesons at Sea Level

Description: 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."

A Transistorized Pulse Height Analyzer for Gamma Spectroscopy

Description: 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."

Determining the "State of Charge" of Nickel-Cadmium Batteries by Farad Capacitance Measurements

Description: From abstract: "A rapid simple method has been developed for determining state of charge of the widely used nickel-cadium rechargeable battery. The method described is based on the experimentally verified relationship between farad capacitance and state of charge."
