Abstract Adhesive tapes were compared by nondestructive gamma-ray spectrometry. Results show that neutron activation analysis can he used to characterize tapes through their elemental composition. Differences between manufacturers as well as hatch-tobatch and in-batch variations can be measured by neutron activation analysis.

Seabirds are very sensitive to environmental changes and due to their large longevity they are also sensitive to cumulative impacts. These birds usually occupy the higher trophic levels. White-chinned petrel (Procellaria aequinoctialis) and black-browed albatross (Thalassarche melanophris) are Procellariiformes, which is a seabird order, composed of 4 families. In the last years, researches are being done and actions are being taken to reduce the mortality of albatrosses and petrels caused by human activities. Due to the great ecological importance of these birds and the developed work with Procellariiformes, this study purpose was to quantify the Br, Cl, Cu, K, Mg, Mn, Na and V elements in white-chinned petrel and black-browed albatross feathers. Bird specimens were killed accidentally by pelagic longline fisheries operating off southern Brazil. Feathers were cleaned with acetone and then milled in a cryogenic mill. Instrumental Neutron Activation Analysis (INAA) was used for quantification of the element concentrations and measurements of induced activities were performed in a High Purity Germanium (HPGe) detector for gamma ray spectrometry. The obtained results on feathers showed that concentrations in these birds are not higher than others studies with the same species and, with exception of Br, there are no significant differences between elements mean concentrations in the two seabirds.

Physical Evidence

Abstract Neutron-activation analysis has been employed to compare “moonshine,” soil, and paint collected as physical evidence during the investigation of illicit distilleries. These materials were irradiated in a DASA-TRIGA nuclear reactor and the induced radionuclides were identified by nondestructive gamma-ray spectrometry. The results obtained indicate the technique can be employed to compare these materials. The findings have been accepted for use in court as evidence.
