Sources of this include the medical use of radioactive materials, fallout and contamination from nuclear bomb tests, discharges from the nuclear industry, and the storage and dumping of radioactive waste. While artificial radiation accounts for a small proportion of the total, its effects can be ...
In this article, we look at the sources of radiation that are not only associated with the production of nuclear power, but also other techniques used to generate desired sources of radiation.doi:10.1016/B978-0-12-819725-7.00097-0David K. Wehe...
160: Ionizing Radiation Exposure of the Population of the United States This report by Committee 6 of the Council is an extensive update of a previous report on the exposure of the US population to ionizing radiation sources from data gathered in the 1980s (published as Report 93 in 1987)....
environmental processes76,229. For comparison purposes, Supplementary Table1lists the inputs of cesium-137 (137Cs), one of the main contributors to radiological impact, to the marine environment from the main sources of man-made radionuclides (i.e., global fallout, discharges from nuclear fuel r...
A general expression is derived for the ratio of the radiated power and the source-integrated intensity for any planar gaussian Schell-model source. The behavior of this quantity, known as the radiation efficiency of the source, is displayed graphically as a function of the rms width of the in...
It is re-emphasized, however, that whenever there is a fluctuating force between the fluid and a solid boundary, a dipole radiation will result which may be more efficient than the quadrupole radiation, at least at low Mach numbers... MJ Lighthill - 《Proceedings of the Royal Society of Lon...
Gamma-ray sources refer to regions in space emitting high-energy gamma radiation, often discovered through satellite missions. Some of these sources remain unidentified and can be categorized based on their location, spectral properties, and association with known objects or phenomena in the Milky Way...
9. The system of claim 8, wherein the second one or more optical elements include an array of collimating lenses. 10. The system of claim 1, wherein the first and second group of one or more radiation sources are mounted on a single movable carriage. 11. The system of claim 1, where...
In the 1920's, reports of radium sources entering the public domain in an uncontrolled manner began to appear in the press and in the literature. Additionally, gold jewelry was made from depleted radon gold seeds which, in some cases, resulted in radiation injuries to the persons wearing the...
Indicators of hippocampal neurogenesis are altered by 56Fe-particle irradiation in a dose-dependent manner. The health risks to astronauts exposed to high-LET radiation include possible cognitive deficits. The pathogenesis of radiation-induced cognitive injury is... R Rola,S Otsuka,A Obenaus,... -...
