Radio carbon dating artifacts
While a crystalline grain such as quartz – found in desert sand – is buried and tucked away from sunlight, natural radiation from surrounding soil and rocks knocks electrons in the crystal out of position.For archaeologists such as Spooner trying to date the first occupation of Australia, older age limitations of radiocarbon dating are frustrating, as it is exactly this period in which they are most interested.So along with radiocarbon dating, they use a technique known as optically stimulated luminescence (OSL) dating.Radiocarbon dating is a method of estimating the age of organic material.
It was developed right after World War II by Willard F.
Around 99% of carbon on earth is carbon-12 – atoms with six protons and six neutrons in its nucleus.
