Yes, the decay of unstable atomic nuclei is the source of nuclear radiation.
Yes, a nuclear reactor produces nuclear radiation. Nuclear reactions in the core produce energy, and they also produce different types of radiation.
Both microwave radiation and nuclear electromagnetic radiation are members of the same species, but they're as different as babies are from elephants, to wit, microwaves are much, much less powerful than nuclear electromagnetic radiation. Microwave radiation, for instance, makes atoms shift their position (and magnetic fields) very, very quickly. Now the definition of heat is "movement," so the faster anything moves, the "hotter" we say it is. Ergo, something placed in a microwave-radiation-field becomes noticeably "hotter." But comparing microwave and nuclear electromagnetic radiation is like comparing a face-slap to a 20-ton BOMB. Nuclear radiation comes from atomic nuclei, so "nuclear radiation" can strike, penetrate, damage, and even destroy atoms in their path. Big difference, capiche? Huge.We left out the part about nuclear particulate radiation. There is no comparison there. Additionally, nuclear electromagnetic radiation is ionizing radiation while microwave radiation is not.
Because it comes entirely from the Atomic Nucleus.
The word nuclear comes from nucleus. Nuclear power comes from the release of binding energy (Strong Atomic Force) in the nucleus of atoms.
Atomic energy is really a misnomer for nuclear energy. It is the fissioning of the nucleus which causes energy to be released. At the atomic level we are dealing with chemical reactions, but in the early days people did talk of atomic power and atomic bombs.

nuclear energy
Nuclear energy
In general, nuclear energy comes from the energy associated with atomic nuclei. There is nuclear fusion, which happens in stars and in fusion weapons, and there is nuclear fission. Nuclear fusion is the "combining" of lighter atomic nuclei to create heavier ones, and many fusion reactions release energy. (Again, think of stars.) In contrast, nuclear fission is the "splitting" of atomic nuclei to release energy. The latter is technology that we've come to use fairly widely, and we have developed fission nuclear weapons and the nuclear reactor to tap nuclear energy via fission. Let's look at the latter device, the reactor. The fission of nuclear fuel (also known as atomic fuel, such as uranium or plutonium) is where we get nuclear energy. And what happens during nuclear fission is that the nuclei of fuel atoms absorb neutrons and fission (split), releasing lots of energy. In fission, that larger atomic nucleus breaks into a pair of smaller ones, and these fission fragments recoil with a lot of kinetic energy. The fuel traps the fission fragments, and the energy they came away with is converted into thermal energy in the fuel. We derive nuclear energy by tapping the energy of formation of atomic nuclei via fusion or fission. This is advanced technology that is less than a century old. We're still working to use it well and wisely.
It comes from the nucleolus of an atom.
The phase in which the chromatin expands and nuclear membranes form in the daughter nuclei is the telophase. The telophase comes after the anaphase.
The energy of nuclear power comes from the binding energy that holds an atomic nucleus together. A heavy nucleus, usually uranium-235, splits into two smaller nuclei and releases three neutrons. These new nuclei have less binding energy than the original, and the excess energy is released as heat.
Because it comes entirely from the Atomic Nucleus.
The word nuclear comes from nucleus. Nuclear power comes from the release of binding energy (Strong Atomic Force) in the nucleus of atoms.
Atomic energy is really a misnomer for nuclear energy. It is the fissioning of the nucleus which causes energy to be released. At the atomic level we are dealing with chemical reactions, but in the early days people did talk of atomic power and atomic bombs.
The energy produced (or rather, converted) in the Sun comes from nuclear energy - that is, it involves changes to atomic nuclei. In this case, four hydrogen-1 atoms combine to one helium-4 atom. (The numbers refer to the isotopes involved.)
Alpha and beta particles are the same in that changes in unstable atomic nuclei can release alpha particles or can beta particles (depending on the isotope involved), and both are forms of particulate radiation.
