One application for the tracer molecule described above would be to monitor plant growth by watering plants with it.
The plants would take up the water and use it in leaves, roots, stems, flowers, and other parts in the same way it does with normal water.
(Radioactivity is the property possessed by some elements of spontaneously emitting energy in the form of particles or waves by disintegration of their atomic nuclei.) For example, it is possible to make a molecule of water in which one of the two hydrogen atoms is a radioactive tritium (hydrogen-3) atom.For example, a number of different oil companies may take turns using the same pipeline to ship their products from the oil fields to their refineries.How do companies A, B, and C all know when their oil is passing through the pipeline?Nevertheless it generates 0.1 watts/tonne as decay heat and this is enough to warm the Earth's core. The nucleus of the U-235 atom comprises 92 protons and 143 neutrons (92 143 = 235).When the nucleus of a U-235 atom captures a moving neutron it splits in two (fissions) and releases some energy in the form of heat, also two or three additional neutrons are thrown off.
