Why are x-rays considered hazardous?

X-rays are considered hazardous primarily because they emit ionizing radiation. This type of radiation possesses enough energy to remove tightly bound electrons from atoms, which can lead to chemical changes in cells and potentially cause damage to biological tissues. This damage is a concern because it increases the risk of cancer and can cause other health issues due to the alteration of DNA within cells.

Ionizing radiation from x-rays has significant implications for both patients and healthcare workers, as repeated or excessive exposure can lead to cumulative effects, increasing the likelihood of adverse health outcomes. Therefore, it is crucial to limit exposure and use protective measures, such as lead aprons or shields, when working with x-ray equipment.

The other types of radiation mentioned, such as electromagnetic radiation, include a broad spectrum of energy types ranging from non-ionizing (like visible light and radio waves) to ionizing radiation. While x-rays fall under the category of electromagnetic radiation, not all forms are hazardous. Longitudinal radiation is not a recognized type of radiation and does not specifically pertain to the hazards associated with x-rays. Thus, the emphasis on ionizing radiation is critical in understanding why x-rays are categorized as hazardous.
