Radioactivity levels and radiological risk assessment in west Antalya beach sands

A radiological baseline study was carried out by means of a computational analysis to evaluate the distribution of ²²⁶Ra, ²³²Th, ⁴⁰K and ¹³⁷Cs in samples of beach sand collected from the coastal areas of Antalya, Turkey. The results of the radiological risk assessment indicated that the calculated radiological risk for workers and tourists was below the level that could pose an endangerment to life or the safe operation. There was also no evidence of recent migration of ¹³⁷Cs or other isotopes through precipitation, dust transport, or by indirect means such as sea currents.
