Accelerator mass spectrometry is not dependent upon the radioactive decay.

What you’re doing is measuring all of the carbon isotopes in the sample – the 12, 13 and 14 – the accelerator operates like a giant mass spectrometer.

A mass spectrometer is an instrument that uses a series of magnets to bend a beam of ions and then physically count how many there are, so with AMS radiocarbon dating, we can measure a carbon-12, 13 and 14 beam, and we measure the ratio of 14 to 13, and from that, we can tell how much C-14 is in the sample.

So the most important things about AMS radiocarbon dating as opposed to conventional is that the sample size is much, much smaller.

AMS is faster and needs a much smaller sample, but is more expensive.

have their origin in other preexisting types and that the distinguishable differences are due to modifications in successive generations.

The discovery of by the French physicist, Henri Becquerel, in 1896 paved the way of measuring absolute time.

The TEM facilitates high resolution imaging of crystallographic and structural features of very thin samples.

The microscopes are used predominantly for research and teaching.

Shortly after Becquerel's find, Marie Curie, a French chemist, isolated another highly radioactive element, .

The realisation that radioactive materials emit rays indicated a constant change of those materials from one element to another.
