In studies of the organ distribution of radioactive thallium (Ti204) in the rat, Thyresson8 and Barclay, et al.' found that on a gram-per-tissue basis this isotope was taken up by the thyroid in large amounts. Twenty-four hours after acute poisoning with a single large dose of T1204, the kidney took up the greatest amount of isotope, followed by the colon and the thyroid in that order.8 It was ...

The NanoSIMS ion probe is a new-generation SIMS instrument, characterised by superior spatial resolution, high sensitivity and multi-collection capability. Isotope studies of certain elements can be conducted with 50–100 nm resolution, making the NanoSIMS an indispensable tool in many research fields. We review technical aspects of the NanoSIMS ion probe and present examples of applications in ...

The lattice location of iron in thin-film, single-crystalline hexagonal GaN was studied by means of the emission channeling technique. Following 60-keV room-temperature implantation of the precursor isotope Mn at a dose of 1.0×10 cm and annealing up to 900°C, the angular distribution of β particles emitted by the radioactive isotope Fe was measured by a position-sensitive electron detector. The...

Neutron-rich radioactive isotope (RI) beams in the vicinity of Zr110 were produced using in-flight fission a 345-MeV/nucleon U238 beam at RIKEN Radioactive Isotope Beam Factory. The RI separated flight by large-acceptance two-stage fragment separator BigRIPS. Isotopes clearly identified low-background particle-identification plot, which was obtained from measurements time flight, magnetic rigid...

Efficient production of short-lived radioactive isotopes in inverse reaction kinematics is an important technique for various applications. It is particularly interesting when the isotope of interest is only a few nucleons away from a stable isotope. In this article production via charge exchange and stripping reactions in combination with a magnetic separator is explored. The relation between ...

The lattice location of rare earth Er in single-crystalline hexagonal ZnO was studied by means of the emission channeling technique. Following 60-keV room-temperature implantation of the precursor isotope Tm at doses of 1.3−2.8×10 cm and annealing up to 900°C, the angular distribution of conversion electrons emitted by the radioactive isotope Er was measured by a position-sensitive electron det...

Natural waters’ carbon isotopes content is an important parameter in many environmental studies, as it hints to the water’s origin and history. Atmospheric water contain a certain amount of dissolved carbon dioxide, in the form of oxygen, hydrogen and carbon through their various species (CO2, HCO3 & CO3), which are commonly used for isotopic characterization of natural water [1]. Carbon posses...

There are 2 radioactive isotopes of iron suitable for use as biological tracers. One of these, Fe59, has a half life of 47 days and emits gamma rays and low energy beta rays. The other, Fe55, has a half life of about 5 years and emits low energy x-rays only. This paper describes how these 2 isotopes are prepared for red blood cell tracer studies, how biological samples containing the radioactiv...

At the Isotope Separation and ACceleration (ISAC) facility at TRIUMF, an electron cyclotron resonance ion source (ECRIS) has been set up for the charge state breeding of radioactive ions. In order to reduce background from stable ions generated in the ECRIS, several measures, including changing materials for the plasma chamber and the surrounding components, have been implemented. Further reduc...
