In this research, measurement of radioactivity of bismuth-212 in the soil of the
village of the Ien Lailonin- Alhafah area- Latakia city using gamma spectrometry to make
sure the radioactive content to soil, and was measuring the radioactivity of b
ismuth-212
using the alpha spectroscopy, after digestion 10g of soil using nitric acid and sulfuric acid
concentrated, and then spontaneaous deposition into high purity a silver disc.
the results show that: the radioactivity of bismuth-212 (1,48Bq) using gamma
spectrometry and (2,05Bq)using the alpha spectroscopy It is within the range allowed
international border ,taking into account the errors in measurements.
Quality Control procedure Of Gamma Spectrometry measurements using
semi conductor HPGe Detectors and determination the uncertainty budget of
the measurements and calibrations have been prepared.
Depending on this procedure we can evaluate the qual
ity of the results to be
accepted or not, and where the correction actions should be used.
