| Abstract: |
As a part of
national survey to evaluate natural radioactivity in the environment,
concentration levels of natural radioactivity have been analyzed from more than
108 environmental samples taken from
wadi
Allaqi area, south Egypt.
The distribution of naturally occurring radionuclides of 226Ra, 232Th
and 40K in the samples (soil, granite, grass and water) have been
measured using a high purity germanium detector. The specific activities in
these samples, having a radium equivalent activity of less than 370 Bq.kg-1,
when evaluated for radiological effects show that all samples meet the external
gamma-ray dose limitation of 1.5 mSv.y-1. The data presented here
will serve as a baseline survey for primordial radionuclide concentrations in
igneous and sediment of the area.
