What distinguishes intrinsic radiation from extrinsic radiation?

Intrinsic radiation is characterized by its origin from natural sources, such as cosmic rays, radon, and naturally occurring radioactive materials within the Earth. This type of radiation is constantly present in our environment and contributes to natural background radiation levels that all living beings are exposed to.

On the other hand, extrinsic radiation originates from man-made sources, such as X-ray machines, medical imaging devices, and radiation therapies. This distinction is crucial in understanding the sources and types of radiation exposure individuals may encounter, particularly in medical and dental settings.

Understanding the difference between intrinsic and extrinsic radiation is essential for professionals in the dental field, as it helps them evaluate and manage radiation safety effectively. While both intrinsic and extrinsic radiation can have health implications, recognizing their sources allows for better implementation of safety protocols and protective measures in practice.
