C is 5,700 ± 30 years. [21] This means that after 5,700 years, only half of the initial 14 C will remain; a quarter will remain after 11,400 years; an eighth after 17,100 years; and so on. The above calculations make several assumptions, such as that the level of 14 C in the atmosphere has remained constant over time. [5] In fact, the level of 14
