Yes, glass can be seen on an X-ray image. Glass is denser than soft tissues in the body, so it appears as a bright white object on an X-ray image. This contrast allows radiologists to easily identify and locate any glass fragments that may be present in the body. **

Uranium glass, also known as Vaseline glass, contains small amounts of uranium, which gives it a green or yellow color and a characteristic fluorescence under UV light. While the uranium content in these glass items is generally considered to be low and not harmful for everyday use, it is still recommended to handle them with care and avoid prolonged exposure. Direct contact with the glass or ingestion of any particles should be avoided, and it is best to keep uranium glass items out of reach of children. Overall, as long as proper precautions are taken, the risk of harm from uranium glass is minimal. **

However, there are steps that can be taken to minimize exposure to X-rays, such as only getting necessary X-ray exams and using protective shielding when undergoing X-ray procedures. It is important to discuss the risks and benefits of X-ray exams with a healthcare provider to make informed decisions about medical imaging. **
