چکیده

We calculate the field emitted by a pulsed point source above a planar interface. It is found that the observed power spectrum can differ significantly from the emitted spectrum. Also, the observed power spectrum depends strongly on the wave speeds in the two media and on the position of the observation point with respect to the interface and the source.

Compliance of Radiation Dose and Image Quality in a Nigerian Teaching Hospital with the European Guidelines for Pediatric Screen-Film Chest Radiography

Introduction Blue light is a part of the spectrum with the highest energy content, which can reach the retina. The damage that it can cause to the retina is called photochemical or blue-light retinal injury. For the retinal injury assessment of the photochemical and aphakic retinal hazards in the wavelength range of 300-700 nm, use of effective spectral radiance limits (W.m-2.sr-1) seems to be...
