Nuclear physics is important in a vast variety of situations, from understanding how the Sun provides the energy for life on this planet, to nuclear power plants and radiation therapy.
La mesure de l’U, du Th et de l’He permet de déterminer le moment de départ du processus de piège de l’He.Authenticating archaeological gold objects is a major problem, as gold is probably the most difficult material in terms of detecting modern forgeries.In 1996 we published the results of the study of faked and genuine gold crystals from the Santa Elena gold mine in Venezuela, and demonstrated that the U/Th – He dating method is a powerful tool for detecting forgeries among gold objects.(Only a handful of nuclides with atomic numbers less than 83 emit an -particle.) The product of -decay is easy to predict if we assume that both mass and charge are conserved in nuclear reactions.
Alpha decay of the The sum of the mass numbers of the products (234 4) is equal to the mass number of the parent nuclide (238), and the sum of the charges on the products (90 2) is equal to the charge on the parent nuclide.
NTI and its partners, Creative Santa Fe and the NSquare Collaborative, have won the 2017 Most Significant Futures Work Award for “analyzing a significant future issue” for the 2016 Disruptive Futures: Santa ...
