What are radiation sources produced by humans called?

The term for radiation sources produced by humans is "artificial radiation." This type of radiation is the result of human activities, such as medical procedures (like X-rays and radiation therapy), industrial processes, and nuclear power generation. Unlike natural radiation, which comes from cosmic and terrestrial sources, artificial radiation does not occur in nature but is generated through human intervention and technology. Understanding the distinction between artificial and natural radiation is crucial in the field of radiation safety, as it helps in assessing exposure risks and managing safety protocols related to human-made radiation sources.
