Thermonuclear fusion is a mighty process that powers the stars. While the nuclei of lighter atoms are fused into heavier ones, plenty of energy is released. The idea of harnessing the energy of the stars for the needs of terrestrial energetics has interested scientists since 1920.

The quest for nuclear energy began with the discovery of radioactivity at the end of the 19th century. Numerous experiments with materials emitting invisible rays led to a better understanding of the makeup of the atom. Ionizing radiation is a natural part of our environment. Its origin lies in the radioactive elements contained in the Earth’s crust, air, plants, and every living organism.
