“…Gamma spectra of induced activity were measured twice, for 3 -5 min after 5 -7 minutes of decay and for 10 -15 min after 20 min of decay. To process gamma spectra and to calculate concentrations of elements, software developed at FLNP JINR was applied [19].…”

The contents of 23 trace elements (Sc, V, Cr, Mn, Fe, Co, Zn, As, Se, Br, Rb, Sr, Mo, Ag, Sb, I, Ba, La, Ce, Sm, Eu, Hf, Ta) were quantitatively determined in soft tissues and shells of mass non-indigenous bivalve mussels-farmed Pacific oysters (Crassostrea gigas) and farmed and wild invasive Mediterranean mussels (Mytilus galloprovincialis) at the Atlantic coast of South Africa. The study revealed that the contents of the majority of elements in the soft tissues of both species were higher than those in the shells. The tissues of wild invasive Mediterranean mussels contain higher levels of a range of trace elements comparing to farmed mussels. The tissues of Pacific oysters contain much higher levels of almost all elements studied compared to the tissues of Mediterranean mussels. Higher content of zinc in the mussels and oysters from Saldanha Bay may evidence anthropogenic pollution of the bay's ecosystem by this metal, which necessitates continued monitoring of levels of potentially toxic metals. Both alien species, and especially Pacific oysters, may serve as reliable biomonitors for trace elements in marine ecosystems. Both species are rich in essential elements and provide nutritionally-valuable seafoods.

The present status of development of software packages and equipment designed for automation of NAA at the reactor IBR-2 of FLNP, JINR, Dubna, RF, is described. The NAA database, construction of sample changers and software for automation of spectra measurement and calculation of concentrations are presented. Automation of QC procedures is integrated in the software developed. Details of the design are shown.

“…In case of long lived isotopes, samples were irradiated for 4 days, repacked and measured twice using high purity germanium detectors, after 4-5 days and 20-23 days of decay for 30 min and 1.5 h, respectively. Data processing and determination of ele ment concentrations were performed using software developed in FLNP JINR [8] (Pavlov et al, 2014). Ele ment contents were determined on the basis of certified reference materials: The total error in the determina tion of 37 elements varied between 5 and 30%.…”
