The 1970s brought further developments in the investigation of trace elements in hair. Two symposia in Atlanta (Georgia) in 1973 and 1978 and a book sought to provide a systematic overview of the development of the previous years [7-9]. 

At this initial session, a simple application should be demonstrated. One of the most successful is to explain the presence of trace elements in hair and to then obtain a hair sample (perhaps two) one of which is cleaned with alcohol and the other not. The resultant spectrum obtained on a Ge detector following sample irradiation is used to demonstrate the capabilities of INAA to identify and quantify trace elements in the hair sample. The presenter must explain this forensic application and extend the discussion to further possibilities in trace element analysis in other areas.
