Hemp seeds, or hemp hearts, have a high nutrition profile and are a healthy addition to most diets. Hemp seeds are the seeds of the same plant as marijuana, the cannabis plant, but they do not contain high levels of THC and will not get you high.
Nuclear explosion. Atomic bomb explosion. A nuclear explosion is energy being released from a very fast nuclear reaction. It can be caused by nuclear fission, nuclear fusion, or both. Atmospheric nuclear explosions are associated with mushroom clouds, although mushroom clouds can occur as a result of large chemical explosions.
Nuclear fission is a process in nuclear physics in which the nucleus of an atom splits into two or more smaller nuclei as fission products, and usually some by-product particles. Hence, fission is a form of elemental transmutation. The by-products include free neutrons, photons usually in the form gamma rays, and other nuclear fragments such as beta particles and alpha particles.
