Use of X-rays in the United Kingdom Forensic Science Service

چکیده
The need for non-destructive methods of analysis in order to preserve evidence can be of great importance, although this requirement may vary from country to country depending upon the prevailing criminal justice system. Most courts understand, and accept, that chemical analysis can result in destruction of a specimen, but in certain instances, Counsel may insist on seeing the specimen that was analysed, and having that same specimen re-analysed by their own scientists. In view of this, it is wise to use non-destructive analytical methods, where possible, as a matter of course. XRD, XRF and Radiography meet this requirement admirably.
