摘要:

By using 14 MeV neutron flux of 3.5 × 1010n/cm2· s, the activities of the activated nuclides in both ferrosilicon alloy (from Kima-Aswan Company) and black sand samples (from the mouth of Damietta, North of Egyptian Delta), were measured. The rate dose of natural gamma-activities arising from Th-232 in the black sand area was calculated.
