This means that half of the c14 has decayed by the time an organism has been dead for years, and half of the remainder has decayed by 11, years after death, etc. Radiocarbon dates can be normalized to any chosen value, and the value chosen by international convention is parts per mil based on an internationally accepted oak standard. Every part per mil difference from is equivalent to 16 years. The temperature at which this happens is known as the closure temperature or blocking temperature and is specific to a particular material and isotopic system. Help us improve this article! Refresh and try again. The standards offer a basis for interpreting the radioactivity of the unknown sample, but there is always a degree of uncertainty in any measurement. By examining the object's relation to layers of deposits in the area, and by comparing the object to others found at the site, archaeologists can estimate when the object arrived at the site.
