We report on the lattice location of ion implanted Cu in Si using the emission channeling technique. The angular distribution of beta(-) particles emitted by the radioactive isotope 67Cu was monitored following room temperature implantation into Si single crystals and annealing up to 600 degrees C. The majority of Cu was found close to substitutional sites, however, with a significant displacem...

A first ?-ray study of Cl47,49 spectroscopy was performed at the Radioactive Isotope Beam Factory with Ar50 projectiles 217 MeV/nucleon, impinging on liquid hydrogen target MINOS device. Prompt deexcitation ? rays were measured NaI(Tl) array DALI2+. Through one-proton knockout reaction Ar50(p,2p), a spin assignment could be determined for low-lying states Cl49 from momentum distribution obtaine...

Abstract The Lu-Hf isotopic system, much like the Sm-Nd can be used to understand crustal evolution and growth. Crustal differentiation processes yield reservoirs with differing initial Lu/Hf values, radioactive decay of 176 Lu results in diverging Hf/ 177 Hf between over time. This chapter outlines fundamentals provides several case studies outlining utility this system mineral exploration und...

Abstract MYRRHA will be the world’s first large-scale Accelerator Driven System project at power levels scalable to industrial systems. ISOL@MYRRHA produce Radioactive Ion Beams (RIBs) using Isotope Separation On-Line (ISOL) technique, with increased isotope production by high intensity primary beams over a long period while maintaining high-quality RIB. Higher atom flux produced prevalently af...

We hypothesize that the “snowballs” observed in HgCdTe infrared detectors are caused by natural radioactivity in the devices themselves. As characterized by Hilbert (2009) in the WFC3 flight IR array (FPA165), “snowballs” are transient events that instantaneously saturate a few pixels and deposit a few hundred thousand electrons over a ~5-pixel (~100-um) diameter region. In 2008, prior to fligh...

Actinides have widely entered the environment as a result of nuclear accidents and atmospheric weapon testing. These radionuclides, especially uranium, are outstanding radioactive pollutants, due to their high radiotoxicity and long half-lives. In addition to this, since depleted uranium (DU) has been used in the Balkan conflict in 1999, there has been a concern about the possible consequences ...

LTERATIONS in the vitansin B12 concentrations of senuns amid umnimsc after the oral or pareisteral adnsitsistratiots of B12 can be followed by mssicrohiological niethods.’7 The imitroduct-iois of radioactive vitamssits B12 labeled with #{176}Co has also nsade it possible to study body distribution of the vitamssims after oral or paremsteral administration to amiinsabs amid humamus.8’3 Changes i...

For a long time now, microorganisms have been employed as a tool in the interpretation of the biological activities of radiations, usually in terms of lethal and genetic effect. In order to maintain standard conditions, recent investigations have been careful to prevent growth during irradiation. Whereupon, the lethal and genetic effects usually have been affected proportionately over a wide do...

The ?-decay scheme of Te138 and the level structure I138 is reported for first time. experiment was performed at Radioactive Isotope Beam Factory RIKEN, as one EUROBALL-RIKEN Cluster Array campaigns. Secondary radioactive ions, including Sb138, were produced by in-flight fission a U238 beam with energy 345 MeV per nucleon. From ? decay Te138, supplemented new spin parity assignments, such low-l...

BACKGROUND AND PURPOSE Recanalization after selective endovascular treatment of intracranial aneurysms with platinum coils has been widely reported in the literature. Beta radiation emitted from (32)P ion-implanted coils can prevent recanalization in animal models. A complete inventory of radioactive coils may not be realistic; our hypothesis was that it might not be necessary to reach target a...
