What happens to x-ray beams or fluoroscopes in many cases?

The correct answer is that x-ray beams or fluoroscopes can extend past the protective lead. This occurs because while lead shielding is very effective at reducing radiation exposure, it does not completely block all radiation. Some low-energy x-ray photons may be able to penetrate through the lead, particularly if the shielding is insufficient or if there are gaps. This is especially important in a medical or dental setting where repeated exposure to these beams can pose health risks to the operator and other staff.

Understanding this principle highlights the importance of using additional protective measures, ensuring that proper techniques are employed, and monitoring radiation exposure levels to minimize risks. Practitioners must always remain vigilant about protecting themselves and others when working with x-ray equipment.
