Broad-and Narrow-Beam Attenuation of 500- to 1,400- Kilovolt X-Rays in Lead and Concrete
There have been numerous papers over the past 10 years dealing with X-ray protection in the range from 500 to 2,000 kv [1 to 6]. The data from these papers differ somewhat, because the conditions of the experiments were not always the same and therefore cannot be readily correlated. Part of this has been attributed to differences in the high-voltage wave form and inherent filtration for the sev...
متن کاملAngular width of a narrow beam for X-ray linear attenuation coefficient measurements
The detection of scattered radiation can be a major source of systematic errors when measuring the X-ray linear attenuation coefficient, m. Angular distributions of scattered photons are studied for Z 1⁄4 1 to 20 at energies 6 keV to 100MeV, using tabulated atomic form factors and incoherent scattering functions. A circularly symmetric pencil beam irradiation geometry is considered, and scatter...
متن کاملThe Pattern of Pediatric Respiratory Illnesses Admitted in Ebonyi State University Teaching Hospital South-East Nigeria
BACKGROUND Reports from the developed nations reveal respiratory tract infections as the leading cause of childhood hospital admissions. Children may be admitted for a variety of respiratory illnesses. Data on the spectrum of pediatric respiratory illnesses admitted in the hospital is scarce. AIM To determine the pattern of pediatrics respiratory illness admissions, seasonal frequency, underl...
متن کاملRadiation attenuation properties of shields containing micro and Nano WO3 in diagnostic X-ray energy range
Background: It has recently been shown that the particle size of materials used for radiation shielding can affect the magnitude of radiation attenuation. Over the past years, application of nano-structured materials in radiation shielding has attracted attention world-wide. The purpose of this study was to investigate the shielding properties of the lead-free shields containing micro and nano-...
متن کاملSimulated sample heating from a nanofocused X-ray beam
Recent developments in synchrotron brilliance and X-ray optics are pushing the flux density in nanofocusing experiments to unprecedented levels, which increases the risk of different types of radiation damage. The effect of X-ray induced sample heating has been investigated using time-resolved and steady-state three-dimensional finite-element modelling of representative nanostructures. Simulati...
