What nuclide is commonly used in the dating of artifacts andrew j west and amber stevens dating
OSL is also less commonly referred to as optical dating, photon stimulated luminescence dating or photoluminescence dating..Luminescence dating methods are based on the ability of some mineral grains to absorb and store energy from environmental ionizing radiation emanating from the immediate surroundings of the mineral grains as well as from cosmic radiation.Stimulation of energy release using heat is termed TL while stimulation using light is referred to as OSL.The age range of luminescence methods generally spans from a few decades to about 100,000 years, though ages exceeding several hundred thousand years have been reported in some studies.But when the rock is exposed to high enough levels of heat or light, that exposure causes vibrations in the mineral lattices and the trapped electrons are freed.Luminescence dating is a collective term for dating methods that encompass thermoluminescence (TL) and optically stimulated luminescence (OSL) dating techniques.Crystalline rock types and soils collect energy from the radioactive decay of cosmic uranium, thorium, and potassium-40.
Two forms of luminescence dating are used by archaeologists to date events in the past: thermoluminescence (TL) or thermally stimulated luminescence (TSL), which measures energy emitted after an object has been exposed to temperatures between 400 and 500°C; and optically stimulated luminescence (OSL), which measures energy emitted after an object has been exposed to daylight.
Particles that make up atoms – the building blocks of matter.
The three basic ones are protons, neutrons and electrons.

Thermaluminesence (TL) and Optically Stimulated Luminesence (OSL) may assist in extending age dating timescales though there is a huge challenge in selecting suitable sampling materials.
