Which types of radiation are emitted by Radon-222?

Radon-222 is a radioactive gas that primarily undergoes alpha decay, which means it emits alpha particles as it transforms into a different element, specifically Polonium-218. Alpha particles are relatively heavy and carry a positive charge, making them significant in terms of health risks when radon is inhaled, as they can cause damage to lung tissue.

In addition to emitting alpha particles, Radon-222 can also emit gamma radiation. Gamma radiation is electromagnetic radiation that is highly penetrating and can be hazardous due to its ability to traverse various materials, including human tissues. The presence of gamma emissions alongside alpha decay makes Radon-222 particularly concerning in terms of radiation exposure and health effects.

The combination of alpha and gamma radiation emission is a critical factor in understanding the risks associated with radon exposure, especially in residential environments where radon might accumulate in enclosed spaces. This understanding is essential for radon measurement technicians when assessing radon levels and formulating mitigation strategies.
