Electromagnetic radiationIn physics, electromagnetic radiation (EMR) consists of waves of the electromagnetic (EM) field, which propagate through space and carry momentum and electromagnetic radiant energy. Types of EMR include radio waves, microwaves, infrared, (visible) light, ultraviolet, X-rays, and gamma rays, all of which are part of the electromagnetic spectrum. Classically, electromagnetic radiation consists of electromagnetic waves, which are synchronized oscillations of electric and magnetic fields.
Nuclear magnetic resonanceNuclear magnetic resonance (NMR) is a physical phenomenon in which nuclei in a strong constant magnetic field are perturbed by a weak oscillating magnetic field (in the near field) and respond by producing an electromagnetic signal with a frequency characteristic of the magnetic field at the nucleus. This process occurs near resonance, when the oscillation frequency matches the intrinsic frequency of the nuclei, which depends on the strength of the static magnetic field, the chemical environment, and the magnetic properties of the isotope involved; in practical applications with static magnetic fields up to ca.
Nuclear power in ItalyNuclear power in Italy is a controversial topic. Italy started to produce nuclear energy in the early 1960s, but all plants were closed by 1990 following the 1987 referendum. As of 2023, Italy is one of only three countries, along with Lithuania and Germany, that completely phased out nuclear power for electricity generation after having operational reactors. An attempt to change the decision was made in 2008 by the government (see also nuclear power debate), which called the nuclear power phase-out a "terrible mistake, the cost of which totalled over €50 billion".
