A method is described for the non-destructive, non-invasive, detection of shell lesions in the New Zealand paua, a marine gastropod Haliotis iris using diagnostic radiology. The X-ray method reliably detected the presence of shell lesions in 96% of the cases examined once lesion dimensions exceeded 6.2 × 7.1 mm. The extent of lesions above this size can be reliably and accurately determined from X-ray images viewed on a video display unit (VDU). Biofouling on the outside of the shell can cause misdiagnoses. This method is a significant animal welfare refinement in the identification of marine gastropods with shell lesions, when compared with traditional techniques which kill the animals.

AbstractThis study proposes non-destructive assessment instrumentation, the X-ray MicroCT scanning, to evaluate archaeological basketry remains prior to any destructive analysis. Three case studies are originating from two archaeological sites in Southeast Europe, with three different stages of preservation (poor, sufficient and very good). In addition, there are two preservation modes—charring and desiccation—along with two conservation situations: treated and untreated with conservation agent fragments. The three different scenarios were chosen to explore the potential range of X-ray MicroCT scanning technology when applied to monocotyledonous small-sized archaeological remains. It was proved that this non-invasive X-ray method is particularly suitable for the often-disadvantaged ancient basketry remains.

Abstract This study proposes non-destructive assessment instrumentation, being the X-ray CT scanning, for the evaluation of archaeological basketry remains prior to any destructive analysis. There are three case studies, originating from two archaeological sites in South-east Europe, with three different stages of preservation (poor, sufficient and very good). In addition, there are two preservation modes – charring and desiccation – along with two conservation situations: treated and untreated with conservation agent fragments. The three different scenarios were chosen to explore the potential range of CT scanning technology when applied to monocotyledonous small-sized archaeological remains. It was proved that this non-invasive X-ray method is particularly suitable in the case of the often-disadvantaged ancient basketry remains.

Some results of non-destructive tests of explosive ordnance (munitions) used by the Polish Armed Forces and performed by X-ray apparatus MU-17F-225-9 from YXLON are presented in the paper. Tests were performed in diagnostic purposes as they are significant for munitions status evaluation process. Received results decide also about the selection of final testing methodology.
