X-ray Effects on Single Nerve Fibers
Electrophysiological responses of median and lateral giant nerve fibers of the earthworm were recorded during exposure, in vitro, to x-rays. In response to external stimulation, during x-irradiation, these nerve fibers showed initially an increase in conduction velocity, a rise in spike amplitude, a decrease in relative refractory period, and an increase in sensitivity. These responses represen...
متن کاملAssessment of Ge-doped optical fibres subjected to x-ray irradiation
We have reported the thermoluminescence (TL) response of five different diameters ~120, 241, 362, 483, and 604 μm of 6 mol percent Ge-doped optical fibres. The perfomance of the Ge-doped optical fibre are compared with commercially available TLD-100 chips (LiF:Mg,Ti) in terms of their sensitivity and minimum detectable dose (MDD). The irradiation was performed using X-ray machine (Model ISO ‘Na...
متن کاملRare-Earth Doped Optical Fibers
An optical fiber becomes active by doping its core with one or more atomic elements, usually (but not restricted to) rare-earths (RE’s), more specifically, the lanthanides that occupy the atomic numbers 57 to 71 of the periodic table. As it will be mentioned later in more detail, they use three electrons in bonding to the condensed materials such as crystals and glasses to become triply ionized...
متن کاملAge-related effects of X-ray irradiation on mouse hippocampus
Therapeutic irradiation of pediatric and adult patients can profoundly affect adult neurogenesis, and cognitive impairment manifests as a deficit in hippocampal-dependent functions. Age plays a major role in susceptibility to radiation, and younger children are at higher risk of cognitive decay when compared to adults. Cranial irradiation affects hippocampal neurogenesis by induction of DNA dam...
متن کاملIndustrial X-ray imaging based on scintillators and CMOS APS array: direct X-ray irradiation effects
To see the effects of the direct X-ray in a Lanex screen-coupled CMOS APS imager, we measured modulation transfer function (MTF), noise power spectrum (NPS), and detective quantum efficiency (DQE). These measurements were performed under the condition of non-destructive test (NDT). By increasing the cumulative exposure on the imager, the MTF was degraded, and also leading to the DQE degradation...
