High demands are set to accuracy, precision and sta-
tisticall interpretation of results.
Forensic application of INAA can be regarded as
an interesting applications; the laboratory may gain
general respect and may demonstrate the social ben-
efit of the technique. However, the number of samples
to be analused and the extent of work is usually limited
and irregular, and this application can therefore be re-
garded as an optional side-activity of the laboratory.
3.5.9 Applications in Art and Archeology
"Fingerprinting" by elemental composition patterns is
a well established technqiue for the idenitification of
pattery, stone and metal artifacts. Applications have
been made to the authentication of works of art and
studiws of materials sources, manufacturing methods
and trading routes. INAA is an important contributor to
this work because it provides a sueful set of elemets
and is well suited to the NDT analysis of large numbers
of small samples.
Another application is the determination of the sil-
ver content coins. Because of inhomogeneity and cor-
rosion the analysis of the whole coin by INAA is often
the only reliable way to do it. The composition of cop-
per and bronze objects can also conviniently be deter-
mined by NAA.
