X-rays are classified as which of the following?

X-rays are classified as carcinogens because they have the potential to cause cancer in living tissues. This classification is based on evidence that ionizing radiation, such as X-rays, can damage the DNA within cells. This damage can lead to mutations that, over time, may result in uncontrolled cell growth, which is characteristic of cancer.

The effects of X-ray exposure depend on several factors, including the dose and duration of exposure, as well as individual susceptibility. Regulatory agencies have identified ionizing radiation as a risk factor for various types of cancer, establishing guidelines for safe exposure levels to minimize risk in medical and occupational settings.

In contrast, allergens are substances that can cause allergic reactions, hormones are chemical messengers that regulate various physiological processes, and vaccines are biological preparations that provide immunity against specific diseases. None of these classifications accurately reflect the nature of X-rays and their potential health impacts, distinguishing carcinogens as the correct classification in this context.
