Journal ArticleDOI
Losses of silver, arsenic, cadmium, selenium and zinc traces from distilled water and artificial sea-water by sorption on various container surfaces
TL;DR: In this paper, the effect of the ratio of inner container surface to sample volume on the sorption loss of 41 elements from aqueous solutions under different experimental conditions was studied.
Journal ArticleDOI
How do we define the concepts specific activity, radioactive concentration, carrier, carrier-free and no-carrier-added?
J. J. M. de Goeij,Mauro Bonardi +1 more
TL;DR: In this paper, the Isotope and Nuclear Chemistry Group participated in programs that involve analysis of fresh fission products by beta counting following radiochemical separations, which is a laborious and timeconsuming process that can take several days to generate results.
Journal ArticleDOI
A new approach to target chemistry for the iodine-123 production via the 124Te(p, 2n) reaction.
R.P.J. van den Bosch,J. J. M. de Goeij,J.A. van der Heide,J.F.W. Tertoolen,H.M.J. Theelen,C. Zegers +5 more
TL;DR: A new approach to target chemistry—comprising target preparation, separation of tellurium and carrier-free radioiodine, and target-material recovery—is presented for routine production of sizeable quantities of iodine-123 for medical diagnosis.
Journal ArticleDOI
Results of a co-ordinated research programme to improve the certification of IAEA milk powder A-11 and animal muscle H-4 for eleven “difficult” trace elements
A. R. Byrne,C. Camara-Rica,R. Cornells,J. J. M. de Goeij,G. V. Iyengar,G. F. Kirkbright,G. Knapp,R. M. Parr,M. Stoeppler +8 more
TL;DR: In this paper, a co-ordinated research program involving a small group of experienced laboratories is described to improve the status of two reference materials, milk powder A-11 and animal muscle H-4, with a wide spread of values for many trace elements of interest.
Journal ArticleDOI
Extended automated separation techniques in destructive neutron activation analysis; application to various biological materials, including human tissues and blood
TL;DR: In this article, an automated post-irradiation chemical separation scheme for the analysis of 14 trace elements in biological materials is described, which consists of a destruction with sulfuric acid and hydrogen peroxide, a distillation of the volatile elements with hydrobromic acid, and chromatography of both distillate and residue over Dowex 2X8 anion exchanger columns.
