Tungsten Alloy Shielding for Radioactivity Logging

Tungsten alloy shielding is necessary for radioactivity logging. Radioactivity logging is physical geographical method which used for researching geologic section of oil drilling, seeking oil, coal or other mineral resources and researching drilling engineering. Radioactivity logging has been widely used in prospection for coal field, uranium mine and oil and becomes one of important measures.

Both nuclear instrument and radioactivity logging utilize characteristics of α-ray, β-ray, γ-ray and neutron ray which released by radioactive isotope. Radioactive source, made of radioactive isotope which can releaseα-ray is called as α radioactive source. Radioactive source, made of radioactive isotope which can releaseβ-ray is called as β radioactive source. Radioactive source, made of radioactive isotope which can release neutron ray is called as neutron radioactive source

Compared with traditional material like lead, tungsten alloy shielding is more suitable for radioactivity logging. The density of tungsten alloy is higher twice than lead. So tungsten alloy has excellent radiation absorption. Otherwise, tungsten alloy is non-toxicity.
