WebBryan et al. also used a short-lived alpha emitter in their research; they have chosen 213 Bi, which has a 46 min half-life. As an antibody carrier they used chimeric mAb chTNT3 … Bismuth is a brittle metal with a dark, silver-pink hue, often with an iridescent oxide tarnish showing many colors from yellow to blue. The spiral, stair-stepped structure of bismuth crystals is the result of a higher growth rate around the outside edges than on the inside edges. The variations in the thickness of the oxide layer that forms on the surface of the crystal cause different wavelength…
