Thermal Neutron Activation Analysis Technique of Rock Samples from Choke Mountain Range, East Gojjam, Ethiopia

Rock samples from Choke Mountain were subjected to elemental analysis by NAA technique with the aim of broadening any database informationon their elemental composition and concentration and accessing the extent of their environmental friendliness. These observations suggest that all particulate emissions and wastes from the Choke Mountain range should be closely monitored to reduce its effects on the environment and health. The instrumental neutron activation analysis technique (INAA) was used in the qualitative and quantitativeanalysis of rock samples from the Choke Mountain area in East Gojjam. A significant advantage of NAA over the techniques is the simplicity of sample treatment before analysis: in most cases, the only requirement is that the sample be reduced to a size suitable for encapsulation. With appropriate experimental parameters, excellent sensitivity is possible for some elements. The primary objective of this work is to determine and identify the various major, minor andtrace elements present in rock samples of Choke Mountain. Their effect on the environment such as people, animals and atmosphere will be discussed.
