Who commonly uses X-rays in their practice?

Healthcare providers and dentists commonly use X-rays in their practice as they are essential diagnostic tools. In the healthcare field, X-rays allow medical professionals to visualize the internal structures of the body, such as bones, tissues, and organs, which is crucial for diagnosing various medical conditions. For example, they are frequently employed in identifying fractures, infections, tumors, and other abnormalities. Dentists use X-rays specifically to assess dental health, detect cavities, examine the jaw structure, and plan treatments like root canals or orthodontics.

The other groups listed may not directly utilize X-rays in their regular professional activities. Physicists might study the principles of X-ray technology or work with it in research settings, but they do not use it as part of everyday practice in the same way healthcare providers and dentists do. Environmental scientists focus on studying and managing environmental health and may use different types of imaging or analysis techniques, but X-rays are not a primary tool in their assessments. Food safety inspectors concentrate on the safety and quality of food rather than using diagnostic imaging like X-rays. Thus, B is the most relevant and accurate option regarding the use of X-rays.
