Radiation Hazard from Natural Radioactivity in the Marine Sediment of Jeddah Coast, Red Sea, Saudi Arabia

Marine sediment samples were collected along the Jeddah coast, Red Sea, Saudi Arabia, in order to assess radiation hazards and exposure human marine living organisms. Using collaborative techniques, grain size, mineralogical characteristics, natural radioactivity investigated. To examine influence of characteristics over distribution measured radionuclides, resulting data statistically processed by using multivariate analyses. 238U, 232Th, 40K levels specified be 19.50, 9.38, 403.31 Bq kg?1, respectively. Radionuclides distributions affected mud content, organic matter, heavy minerals index. The calculated risk parameters are within safe range lower than global average. Natural from these sediments is normal poses no significant radiological public or this coastline will have monitored on a regular basis avoid overexposure residents.
