What are RDPs in relation to radon?

Radon decay products, commonly referred to as RDPs, are the radioactive elements that result from the decay of radon gas. When radon gas is released from the ground and enters homes, it undergoes radioactive decay to form a series of short-lived isotopes. These decay products, such as polonium-218 and lead-214, are of particular concern because they can attach to dust and other particles in the air, becoming inhaled by individuals. This inhalation poses health risks, as these particles can emit radiation in the lungs, potentially leading to lung cancer over time.

Understanding radon decay products is crucial for effective radon measurement and mitigation strategies. Knowing their behavior and how they associate with radon levels in residential and occupational environments helps assess the risk associated with radon exposure. This knowledge enables professionals to implement appropriate radon testing and mitigation techniques to ensure safer indoor air quality.
