ABSTRACT
Scientific investigations have long concluded that prolonged
exposure to low dose of radioactivity can induce deleterious
effects in human. The aim of this work is to investigate the
radioactivity in black sand and its components that are
suspected to have natural radioactivity radiation risk in
Egypt. High-resolution gamma-ray spectrometry (HPGe)
detector was used to detect the radioactive elements
abundance in "Abu-Khashaba" located at 5 Km east of Rosetta
north Nile Delta. It was noticed that, Radium, thorium and
potassium are concentrated in black sand and its components
especially monazite and zircon. Radium equivalent activity (Raeq),
outdoor and indoor external dose and total average annual
effective dose were measured. The hazard indices and total
excess lifetime cancer risk (ELCR) were measured to be
higher than the worlds average values for most samples. The
harmful radiation effects are posing to human going to the
area under investigation.
Key words: Black sand, HPGe Detector, Activity
concentration, Annual effective dose rate, Excess life time
cancer risk (ELCR).
