Typically, a Master's Degree in chemistry is required because of the extensive lab work.Increasingly though, students are learning about the principles of radiocarbon dates in archaeology, palaeontology and climate science degrees and can combine cross-disciplinary studies.By analyzing the concentration of the certain isotopes, such as krypton-81 or helium-4 dissolved in groundwater, scientists can calculate precise time scales of when water was recharged in aquifers, how fast it flows, and how long it takes to replenish.Water shortage is a constant problem in Tunisia and much of the available groundwater resources are shared among Algeria, Tunisia and Libya.This is because the amount of krypton and helium in groundwater is extremely small and its analysis requires state-of-the-art equipment, which is not easily accessible for many Member States.

There are a number of ways to enter into a career in studying radiocarbon dating.

The Tubarao aquifer faces on an urgent water shortage due to the rapid growth of population and industrial necessities.

“Knowing views of other researchers enriched my knowledge in the field of groundwater assessment and allowed me to have a self-critical view of what can be done to improve our research,” said Ezaki.

date of organic material - but an approximate age, usually within a range of a few years either way.

The other method is “Relative Dating” which gives an order of events without giving an exact age (1): typically artefact typology or the study of the sequence of the evolution of fossils.
