Thermal-neutron capture for A=26-35

Description: The prompt gamma-ray data of thermal- neutron captures fornuclear mass number A=26-35 had been evaluated and published in "ATOMICDATA AND NUCLEAR DATA TABLES, 26, 511 (1981)". Since that time themanyexperimental data of the thermal-neutron captures have been measuredand published. The update of the evaluated prompt gamma-ray data is verynecessary for use in PGAA of high-resolution analytical prompt gamma-rayspectroscopy. Besides, the evaluation is also very needed in theEvaluated Nuclear Struct… more

Further Study of Hematological Changes in Humans Chronically Exposed to Low Level Gamma Radiation

Description: This technical report summarizes the apparent hematological changes in 10 individuals, exposed to total-body gamma radiation in near tolerance amounts, over a period of four and one-half years. Two control groups, in addition to the exposed group, were used for comparative purposes. Control group I received essentially no gamma or beta radiations. Control group II received exposures at least a factor of 10 below those of the exposed group. The average total leukocyte count, absolute neutrophil… more

Radiation Chemistry of Ammonia Synthesis of Hydrazine

Description: The radiation chemistry of ammonia, pure or with various additives, was studied by Co60 gamma radiation. The kinetics of aniline formation by the irradiation of homogeneous benzene-ammonia mixtures was determined together with the kinetics of hydrazine formation in the case of pure ammonia. The effects of dose, intensity, temperature, and specific additives were determined.

Analytical Method of Determining Transmission of Particles and Radiation Through Great Thickness of Matter

Description: "A matrix method of determining transmission, scattering, and absorption of radiation, such as gamma rays and neutrons, in large thickness of matter is presented. Experimental data as yet unavailable are required for complete utilization of the method. Material radioactivity whose intensity may be considered to be independent of time is also treated" (p. 1).

Gamma Ray Efficiencies for Well Type Scintillation Crystals

Description: From Abstract : "Gamma ray efficiencies for various sized well type NaI(Ti) crystals have been calculated using an IBM 704 digital computer. The adjustable parameters in the program are the gamma ray energy, the heights and diameters of the crystal and the well, the thickness of the well lining, and the positions of the (point) source inside the well. Some typical results are presented in graphical form."

Response of a LaBr3(Ce) Detector to 2-11 MeV Gamma Rays

Description: The development of lanthanum halide scintillation detectors has great potential application in field-portable prompt-gamma neutron activation analysis systems. Because the low-energy response of these detectors has already been well-characterized [1[-[2], we have measured their response to higher energy gamma rays in the region between 2 and 11 MeV. We have measured the response of a 2-inch (5.08 cm) by 2-inch long LaBr3(Ce) detector to high energy gamma rays produced by neutron interactions on… more

Aerial Gamma-Ray and Magnetic Survey of the Delta Area--Utah: Final Report, Volume 1

Description: From abstract: Results of an ERDA-sponsored, high-sensitivity, airborne gamma-ray spectrometer and magnetometer survey of a portion of the Delta, Utah, NTMS, 1:250,000 scale quadrangle, carried out under Bendix Field Engineering Corporation Subcontract 76-019-L are discussed. The objective of the survey was to evaluate the Delta area as a uraniferous province, i.e., a region showing surface indications of a generally higher uranium content, and evidence of geochemical uranium enrichment over th… more

A Scintillation Spectrometer for Routine Use

Description: From abstract: An automatic gamma-ray spectrometer for routine assays in radiochemical investigations has been constructed. Circuits are described for the automatic control of the pulse analyzer bias and automatic recording of the counting data. Typical gamma-ray spectra are shown as an indication of the perfomance obtained.

Tables for Determining Reduction of Energy and Intensity of X-Rays and Gamma-Rays at Various Scattering Angles in Small Thickness of Matter

Description: Report presenting tables for determining the total-absorption coefficients as well was the intensities and spectral distribution of gamma rays at any scattering angle. Both experimental and computed data on gamma rays of quantum energies up to 20 million electron volts for all elements which have significant data available are provided. The accuracy of results is obtained by the use of tables.

An Experimental Study of the Performance of a Cavity Type Ionization Chamber

Description: Abstract: "Comparisons between calorimetric and ionization chamber measurements of the power generated in graphite by absorption of energetic gamma rays have been carried out. The results serve as a calibration of the chamber. They also serve to test the consistency between the theoretical performance of this type of chamber and previously determined values for the factors which relate ionization in the chamber to energy absorption in the walls."

The Use and Calibration of Scintillation Counter--Model Y

Description: Several improvements have been made in the gamma scintillation counter (GSC). The Model V gamma scintillation counter uses a canned thallium activated sodium iodide crystal as a detector. Although the electronic components remain unchanged, a modification of the sample support has been made to improve reproducibility of geometry. To assure comparable results between various counters, they must be operated at the same energy threshold and counting yield. Methods have been developed to assure… more

Stability of Florothene Under Exposure to Gamma Radiation

Description: The stability of fluorothene (polytrifluorochloroethylene, Kel-F) to gamma radiation has been investigated to estimate the probable life expectancy of fluorothene equipment exposed to Purex process solutions. Samples of fluorothene were exposed to total gamma radiation dosages up to 10 degree R. The results of these tests substantiate the findings reported by Sisman and Bopp in their compilation of data on the affects of radiation on plastics.

Electron Spin Resonance Studies of Gamma-Irradiated Ferrocene

Description: The object of this study was to determine the nature of the free radicals induced in ferrocene by Co60 gamma rays. The irradiations were carried out on the powder at 77°K and on the single crystals at 193°K. The variation of the splitting factor, g, of the signals observed when the single crystals were oriented at different angles relative to the external magnetic field direction, indicated the existence of three types of resonance peaks. It was possible to correlate these variations with the m… more
