Stars are light sources. They emit light and energy through nuclear fusion reactions happening in their cores. The light we see from stars is produced by the immense heat generated from these reactions.
The reactions that take place on the sun are nuclear fusion reactions. Stars are, after all, giant nuclear fusion engines. On our neighborhood star, hydrogen is being fused into helium in the proton-proton chain. In this reaction, two protons are fused and one of them undergoes a beta decay to become a neutron, producing deuterium. There are a couple of different ways the fusion reactions can go from there, but helium eventually results. The process by which stars "run" is called stellar nucleosynthesis, and you can use the links below to investigate further.
Inside the sun, nuclear fusion reactions occur where hydrogen atoms combine to form helium, releasing vast amounts of energy in the process. This energy, in the form of heat and light, creates the intense pressure and temperature required to sustain these fusion reactions and keep the sun shining.
To identify evidence of fusion occurring inside a star, one can look for the emission of light and energy, particularly in the form of X-rays and gamma rays, which are produced during nuclear reactions. Additionally, the presence of specific elements, such as helium in a hydrogen-rich star, can indicate fusion processes, as fusion transforms hydrogen into helium. Stellar models and observations of temperature and pressure in the star's core also support the theory of fusion, as these conditions are necessary for the process to occur. Finally, the observed luminosity and stability of stars align with predictions from fusion models, further corroborating the occurrence of nuclear fusion.
Iron is the heaviest element that can be produced by normal processes inside a star through nuclear fusion. Elements heavier than iron are typically formed in supernova explosions or through other stellar processes.
Because it is produced by reactions happening inside the nucleus.
The primary type of radiation that occurs in a nuclear power station is ionizing radiation, which includes gamma rays, alpha particles, and beta particles. These forms of radiation are produced during nuclear processes such as fission reactions inside the reactor core.
You would look for high-energy electromagnetic radiation like gamma rays emitted from the star. This type of radiation is produced during nuclear fusion reactions when light atomic nuclei combine to form heavier nuclei and release energy. Detection of gamma rays can provide evidence that nuclear fusion is taking place in the core of a star.
We are constantly bombarded by cosmic radiation from space, and background radiation from the soil. However, both are background, and we have no biological processes that depend on nuclear reactions to survive.
Reactors are typically made from concrete,steel and lined with lead, the combination of these materials and built into a strong shape(bullet shaped or spherical shaped etc..) make up a nuclear reactor, these materials also absorb the radiation produced inside the nuclear reactor(lead absorbs gamma radiation and concrete absorbs neutron radiation).
Nuclear reactors use controlled nuclear fission reactions to generate heat, which is then used to produce steam that drives turbines to generate electricity. The heat is produced in the reactor core where nuclear fuel rods containing uranium or plutonium undergo fission reactions. The reactor's cooling system helps regulate the temperature and prevent overheating.
Sunblock is made to block Ultraviolet radiation. Nuclear radiation, or Gamma radiation, is much more energetic and will easily penetrate zinc oxide sunblock, walls, and most everything else except several feet of concrete or a few inches of lead. In addition to Gamma radiation, nuclear reactions also give off less energetic particles called Alpha and Beta particles which can be inhaled and cause damage, which is why the Japanese are wearing wet wipes inside their face masks.
Nuclear radiation is used to make batteries for spacecraft. Nuclear radiation is used in ionizing smoke detectors. Nuclear radiation creates much of the heat inside the earth. Without it the core would solidify and earth would not be habitable.
Nuclear reaction inside the Sun is fusing of Hydrogen to Helium and release out thermal energy.
The sun, arc welding, "black lights" (looking fro fluorescence). [inside florescent lights - but its blocked by the surface of the bulbs.)

No. The only radiation produced by some Xerox machines is light, and some electromagnetic radiation.
