Nuclear Energy
The energy of a nuclear bomb comes from inside the nucleus of the atom. Mass is converted into energy according to E = mc2. This energy is the binding energy of the nucleus, the glue that keeps the nucleus of the atom together. Radiating particles In some cases, the nuclear force is not able to keep a nucleus all together, and the nucleus loses some of its particles. French physicist Henri Becquerel accidentally discovered this

Nuclear Radiation
Ionizing radiation has many practical uses, but it is also dangerous to human health. Both aspects are discussed below. Ionizing radiation is either particle radiation or electromagnetic radiation in which an individual particle/photon carries enough energy to ionize an atom or molecule by completely removing an electron from its orbit. If the individual particles do not carry this amount of energy, it is impossible for even a large flood of particles to cause ionization. These

Nuclear Weapon
The nucleus of an atom can interact with a neutron that travels nearby in two basic ways. It can scatter the neutron - deflecting the neutron in a different direction while robbing it of some of its kinetic energy. Or it can capture the neutron, which in turn can affect the nucleus in several ways - absorption and fission being most important here. The probability that a particular nucleus will scatter or capture a neutron
