An automated neutron activation analysis data acquisition system has been assembled from commercially available equipment.
The modifications of the components needed to make this into a working system are described in the text. The main components
of the data acquisition system are a sample changer, a Ge(Li) detector, a magnetic tape deck and a minicomputer based multichannel
analyzer. The sample changer has a 200-sample capacity and can handle both solid and liquid samples. Software for controlling
the data acquisition system is flexible, yet simple to use. The system has operated reliably for a year and has sharply reduced
the effort needed for data acquisition.
The behaviour of 66 radio-ions towards 11 exchangers and 11 solutions under standardized experimental conditions has been
evaluated and classified in order to have the possibility of a rapid assessment of radiochemical separation procedures. Two
systems of utilizing the bulk of data obtained have been devised and employed. The first is based on the use of a deck of
cards similar to those used for fast retrieval of bibliographic information, in which the behaviour of ions is coded by means
of punched holes; the second is based on the treatment of the data by means of an electronic computer. The operational modes
of the two systems and examples of their practical applications are presented.

However, the properties of WF-PVC may be unsatisfactory if the composites encounter severe thermal and/or chemical degradation [ 15 ]. Processors are strongly advised to
