Monograph on ionizing radiation effects on molecular biology of Escherichia coli, discussing cellular damage, DNA degradation and synthesis, incorporating radioactivity, mutations, etc
Tritium and Ar radioactivities attributable to galactic and solar cosmic ray interactions in Apollo 11 lunar rocks and soil
Auger spectra characteristics obtained with X rays and electrons from radioactive alpha sources
New furnace calibrates unknown thermocouple by comparing its electrical output to a reference thermocouple /previously calibrated by optical pyrometry/, as both are heated simultaneously. Thermocouples may be radioactive, thus heat source must be accessible by remote manipulation and inspection measurements. Advantages of furnace operation are cited.
Radioactive age determination and isotopic composition analyses on rocks, meteorites, and lunar samples
Tables of uranium thorium lead isotopic decay and growth functions for radioactive age determinations
Radioactive abundances and stable products in chronological model for galactic heavy element nucleosynthesis
Mass spectrometry, Mossbauer spectrometry, and radioactivity measuring instruments
Chemical composition and radioactivity analyses of lunar surface materials
Comparison of aluminum 26 radioactivities of Bruderheim chondrites, lunar rocks, and achondrites
Method for producing neutrons in keV energy region utilizing gamma rays from radioactive decay to induce photoneutron reaction in beryllium
Apollo 11 lunar soil sample derived from basaltic and anorthositic rocks, considering basalt origin by melting due to internal radioactive heating
Iron corrosion product deposition on pipe wall from aqueous stream dependent on shear rate, using radioactive tracer technique
Gas proportional counting system gain stabilization, using feedback loop radioactive X ray emitter and correction signal
Ion migration direction in thin Ag, Cu and Au films under direct current effect from resistance radioactive tracer measurements and scanning electron micrographs
Radioactive decay energy conversion of beta particle emitting cerium 144 into high voltage electricity in coaxial cylinder cell
Lost City meteorite Ar isotopes radioactivity measurements, considering cosmic ray flux radial gradient variations during meteoroid orbit
Objectives of the manual are to (1) ensure compliance with requirements of AEC and governmental health agencies, (2) ensure against excessive and unnecessary exposure of personnel to harmful radiation, and (3) prevent contamination of equipment, materials, and environment with radioactive materials.
