Abstract
A transportable and robust gamma ray detection system (GISPI) was employed to
determine the concentrations of naturally occurring radionuclides on various beaches in and around
Saldanha Bay, located on the West Coast of South Africa. Several mathematical techniques were
applied to obtain GIS overlay that could be used to investigate various geophysical phenomenon. The
results demonstrated direct relationships between radionuclide concentrations, grain size of beach
sediment and the intensity of wave action. The element concentrations were used to make deductions
on the origin of some of the beach sand. The article finally draws conclusions on coastal and beach
formation processes, based on the results of the distribution of various
radionuclides.
