It was confirmed by fecal excretion test and Schilling's urinary excretion test using vitamin B@12 labelled with @60Co (@60Co-B@12) that the intestinal absorption of vitamin B@12 was markedly disturbed in patients with pernicious anemia. When @60Co-B@12 was given by mouth together with hog intrinsic factor in patients with pernicious anemia, the intestinal absorption of @60Co-B@12 was restored ...

Changes in bamboo composition and microstructure following 60Co gamma (γ) ray irradiation were investigated by solid state 13C crosspolarization (CP) magic-angle spinning (MAS) spectroscopic nuclear magnetic resonance spectrometry (NMR) and a field emission scanning electron microscope (FESEM). The results indicated that irradiation doses lower than 100 KGy resulted in the degradation of hemice...

Recovery of trivalent minor actinides or the transuranium elements from highly active raffinate could be industrially achieved by innovative Selective ActiNide EXtraction (i-SANEX) and Grouped (GANEX) processes, respectively. All chemicals involved in partitioning must resistant to acidic radioactive environments since hydrolysis radiolysis can have a huge impact on process safety performance. ...

The next generation of γ-ray detector arrays will be composed of large volume high purity germanium (HPGE) detectors that are electronically segmented. These detectors will be able to track γ-rays as they Compton scatter within the crystal and between adjacent crystals, eliminating the need for Compton suppression detectors and improving angular resolution. The new arrays will have much higher ...
