What type of particles are emitted during the decay of Radon?

Radon decay primarily emits alpha particles, which are composed of two protons and two neutrons bound together. This makes alpha particles relatively heavy and positively charged compared to other types of radiation. When radon undergoes radioactive decay, it transforms into other elements and releases alpha particles as a means of achieving stability.

Alpha particles have a limited range and can be stopped by a sheet of paper or even the outer layer of human skin. However, if ingested or inhaled, they can pose significant health risks due to their high energy and potential to damage internal biological tissues. Understanding this aspect of radon's decay is essential for assessing health risks associated with radon exposure, highlighting the need for proper mitigation strategies in areas where radon is present.
