spectral gamma 740

  • Electromagnetic Spectrum

    Gamma-Rays The term gamma ray is used to denote electromagnetic radiation from the nucleus as a part of a radioactive process. The energy of nuclear radiation is extremely high because such radiation is born in the intense conflict between the nuclear strong force and the electromagnetic force, the two strongest basic forces .

    WELLOG SPECTRAL GAMMA. WHAT IS GAMMA SPECTROSCOPY:. Gamma spectroscopy is a passive method that senses naturally occurring gamma rays having different energy levels. Gamma ray sources are comprised of many different elements, for example Uranium and Thorium, which have different energy levels. The different energy levels are identified by scintillation pulses that have

  • Visible Light Spectrum Overview and Chart

    The visible light spectrum is the section of the electromagnetic radiation spectrum that is visible to the human eye. Essentially, that equates to the colors the human eye can see. It ranges in wavelength from approximately 400 nanometers (4 x 10 -7 m, which is violet) to 700 nm (7 x 10-7 m, which is red). It is also known as the optical spectrum of light or the spectrum of white light.
