Magnesium Basic Facts Atomic Number: 12 Symbol: Mg Atomic Weight: 24.305 Discovery: Recognized as an element by Black 1775; Isolated by Sir Humphrey Davy 1808 (England). Magnesium first came into use as magnesium sulfate or Epsom salt. The story goes that in 1618 a farmer in Epsom, ...
The linear attenuation coefficient (μ), mass attenuation coefficient (μ/ρ), total atomic cross-section (σtot), total electronic cross-section (σele) and the effective atomic number (Zeff) were calculated for pure magnesium ferrite (MgFe2O4). The values of γ-ray mass attenuation ...
