Abstract:
The technological development, using atomic, and nuclear energy in industry, agriculture, nuclear
medicine, nuclear wars and tests may increase environmental pollution with noticeable concentrations of man-made radionuclides in the environment. This experimental work aims at the
determination of radium equivalent activity from the soil samples collected from sites extending
from Benghazi city to the Libyan-Egyptian borders, along 600 km. Samples collected from fifty
chosen sites, kept for four weeks to get a secular equilibrium between 226Ra and 232Th and their
corresponding daughters. The result indicated that the value of radium equivalent (Raeq) ranged
from 208.919 to73.881 Bq/kg, with an average of 117.587 Bq/kg
