What effect does prolonged exposure to radiation have on dental staff?

Prolonged exposure to radiation has a well-documented association with an increased risk of cancer, especially for dental staff who frequently work with X-ray equipment. This is primarily due to the ionizing nature of the radiation used in dental imaging, which can cause cellular damage and mutations. Over time, repeated exposure without adequate protection can accumulate, leading to an elevated risk of developing cancer, including leukemia and other malignancies.

Dental professionals are trained to use protective measures, such as lead aprons and thyroid collars, and to minimize exposure time and distance from the source of radiation. However, the cumulative effect of even low levels of radiation can increase the risk of long-term health issues, making awareness and safety protocols crucial for those in the field. The other options do not accurately reflect the significant health risk associated with radiation exposure, reinforcing the importance of safety and risk management among dental practitioners.
