Power(W) Operating Voltage Range (V) Power Factor CRI CCT(K) Lumen (lm) IP Life(Hours) 4 Feet 18W CW Tubelight: FLTL18/04CWG13ID The linear attenuation coefficient, attenuation coefficient, or narrow-beam attenuation coefficient characterizes how easily a volume of material can be penetrated by a beam of light, sound, particles, or other energy or matter. A coefficient value that is large represents a beam becoming … Se mer The attenuation coefficient describes the extent to which the radiant flux of a beam is reduced as it passes through a specific material. It is used in the context of: • X-rays or gamma rays, where it is denoted μ and measured in cm ; Se mer When a narrow (collimated) beam passes through a volume, the beam will lose intensity due to two processes: absorption and scattering. Absorption indicated energy that is lost from the beam, while scattering indicates light that is redirected in a (random) … Se mer • Absorption (electromagnetic radiation) • Absorption cross section • Absorption spectrum Se mer Attenuation coefficient The attenuation coefficient of a volume, denoted μ, is defined as $${\displaystyle \mu =-{\frac {1}{\Phi _{\mathrm {e} }}}{\frac {\mathrm {d} \Phi _{\mathrm {e} }}{\mathrm {d} z}},}$$ where Se mer The mass attenuation coefficient, mass absorption coefficient, and mass scattering coefficient are defined as Se mer Decibels Engineering applications often express attenuation in the logarithmic units of decibels, … Se mer • Absorption Coefficients α of Building Materials and Finishes • Sound Absorption Coefficients for Some Common Materials • Tables of X-Ray Mass Attenuation Coefficients and Mass Energy-Absorption Coefficients from 1 keV to 20 MeV for Elements Z = 1 to 92 and 48 Additional Substances of Dosimetric Interest Se mer
