No, the Bremsstrahlung electromagnetic radiation produced in nuclear fusion is not of the same kind as the electromagnetic radiation produced by hot bodies, such as infrared radiation.
Bremsstrahlung radiation is generated when charged particles, such as electrons or ions, are accelerated or decelerated by the electric fields of atomic nuclei or other charged particles. In the context of nuclear fusion, Bremsstrahlung radiation is produced when high-energy charged particles, such as alpha particles or energetic electrons, interact with the surrounding plasma or material. This interaction leads to the emission of high-energy photons (electromagnetic radiation), typically in the X-ray or gamma-ray range.
On the other hand, the electromagnetic radiation produced by hot bodies, like the infrared radiation we generate, is a result of the thermal motion of charged particles within the body. As the temperature of an object increases, the thermal motion of its constituent particles also increases. This motion generates electromagnetic radiation across a range of wavelengths, including infrared. The intensity and distribution of the emitted radiation depend on the object's temperature and its spectral emissivity.
While both Bremsstrahlung radiation and thermal radiation from hot bodies are forms of electromagnetic radiation, they arise from different physical processes and have distinct characteristics in terms of their energy, wavelength, and origin.
