= Radiation zone
{wiki=Radiation_zone}
The radiation zone is a region within a star, specifically in stars like the Sun, where energy produced in the core is transported outward primarily through radiation. This zone is found between the inner core, where nuclear fusion occurs, and the outer convective zone. In the radiation zone, the high temperature and pressure conditions cause photons (light particles) to be absorbed and re-emitted by particles in the plasma, leading to a slow transfer of energy outwards.
