Radiocontrast agent

including visible light (such that it appears very white when used as a white pigment for paints)

As the electrons produced by the gaseous tritium are so low in energy

STEM BOX: Levitation with Space Age Materials (Ages 12&Up with Adult Supervision) brain-teaser Radiocontrast agentMagnetic Levitation Few materials can be made to magnetically levitate stably above the magnetic field from a permanent magnet. Although you can obviously and easily achieve magnetic repulsion between any two magnets, the shape of the field causes the upper magnet to push off sideways, rather than remaining supported, rendering stable levitation impossible for magnetic objects (see Earnshaw's Theorem). Strongly diamagnetic materials, however, can
