In Depth Analysis of a Sediment Core from North Aegean Sea

In this work a thorough analysis of the vertical distribution natural and artificial radionuclides trace elements in sediment core sample was conducted. A 39 cm length grabbed from deep-sea trench (1540 m depth) southern Samothrace Island, Aegean Sea. The then treated at Hellenic Centre for Marine Research, separated 1cm increment samples, ranging 0cm to cm, dried, milled. first samples also conducted HCMR using gamma spectroscopic techniques. Further continued Nuclear Engineering Department National Technical University Athens (NED-NTUA) an Extended Range Germanium Detector. following were determined 210Pb, 234Th, 226Ra, 228Ra, 228Th, 137Cs 40K. Additionally, Instrumental Neutron Activation Analysis used major identified quantified: Al, V, La, Sc, Mn, As, Ga, Cr, Zn, Co, Rb, Fe, K, Na Ce. Based on each sample, most showed no significant variation. anthropogenic very low almost constant. Unsupported 210Pb activity about six times higher than indicating high radon fluxes. Furthermore, neutron activation results indicate that all are within expected range based literature, while K show slightly increased concentration. For area, these findings steady calm sedimentation processes.
