This method requires less than 1g of bone, but few countries can afford more than one or two AMSs, which cost more than A0,000.

Australia has two machines dedicated to radiocarbon analysis, and they are out of reach for much of the developing world.

The second difficulty arises from the extremely low abundance of C, making it incredibly difficult to measure and extremely sensitive to contamination.

Australian National University provides funding as a member of The Conversation AU.

In addition, samples need to be thoroughly cleaned to remove carbon contamination from glues and soil before dating.

This is particularly important for very old samples.

Radioactive decay can be used as a “clock” because it is unaffected by physical (e.g. For instance, the amount varies according to how many cosmic rays reach Earth.

This is affected by solar activity and the earth’s magnetic field.
