spectral gamma 740

Electromagnetic spectrum - Sun

The electromagnetic spectrum is the range of all possible wavelengths of electromagnetic radiation, ranging from high energy gamma rays through visible light and down to low energy radio waves. Various astronomical phenomena can only be observed via specific wavelengths different from visible light.

Natural Radioactivity - an overview | ScienceDirect Topics

If a spectral gamma measurement is available, the use of thorium and potassium for shale content derivation is recommended. Fertl (1983) noted that the thorium curve of a spectral gammalog allows a quantitative clay volume estimate despite the presence of varying amounts of uranium and potassium (possibly due to mica, especially muscovite, as ...

Clues from gamma rays on the history of star birth | Science

Nov 30, 2018· The effect is a γ-ray flux suppression that increases with the distance of the emitter and the photon energy. Gamma-ray absorption can be studied as a function of the redshift (the displacement of spectral lines toward longer wavelengths due to the expansion of the Universe; it is used as a distance tracer) of a large number of emitting sources.

At energies ≤100GeV, gamma rays observed at Earth and coming from redshift ≥1 inter-act mostly with UV photons of ≥5electron volts. An UV background in excess of the light emitted by resolved galaxies can be produced locally by AGN or at higher redshift (z≈7-15) by

12. THE SPECTRAL GAMMA RAY LOG 12.1 Introduction

12.10 Uses of the Spectral Gamma Ray Log The spectral gamma ray log is an extremely useful log, especially for subtle lithological and compositional analysis, which benefits from its high vertical resolution. In the analysis of spectral gamma ray data, use is commonly made of the ratios of the abundances of the main radioactive sources.

The similarity of spectral gamma ray emission through the Port na Spaniagh Member of North Antrim (Fig. 6, Fig. 7, Fig. 8) and IBF of Mid Antrim (Fig. 3 and Table 1) parallels the rather homogenous outcrop lithostratigraphy as well as the summarised mineralogy for all 14 sections studied (Hill et al., 2000 and Table 2 in this work).

Electromagnetic spectrum - Wikipedia

The convention that EM radiation that is known to come from the nucleus, is always called "gamma ray" radiation is the only convention that is universally respected, however. Many astronomical gamma ray sources (such as gamma ray bursts) are known to be too energetic (in both intensity and wavelength) to be of nuclear origin. Quite often, in ...
