Long Half-Life in Radioactive Decay
... The temperature of Earth’s core is estimated to be ̴7,000 K. As a result, average temperature increases by about 1° F for every 70’ of depth. Most of this heat occurs from long lived radionuclides like uranium-238, thorium-232, and potassium-40. The numbers are the isotope atomic weights. The rest c ...

X-ray fluorescence
X-ray fluorescence (XRF) is the emission of characteristic ""secondary"" (or fluorescent) X-rays from a material that has been excited by bombarding with high-energy X-rays or gamma rays. The phenomenon is widely used for elemental analysis and chemical analysis, particularly in the investigation of metals, glass, ceramics and building materials, and for research in geochemistry, forensic science and archaeology.
