What is a significant hazard associated with handling radiographic sources?

Handling radiographic sources involves a significant risk of exposure to ionizing radiation, which is the correct answer. Radiographic sources, such as isotopes used in non-destructive testing, emit ionizing radiation, which can cause harm to living tissue. This exposure can lead to immediate effects, such as radiation burns, and long-term effects, including an increased risk of cancer.

Understanding the potential for ionizing radiation is crucial for anyone involved in industrial radiography, as appropriate safety measures must be implemented to protect personnel from these hazards. This includes the use of shielding, adherence to regulated safety protocols, and proper training to minimize exposure.

While chemical burns, electrical shock, and exposure to high temperatures may certainly be hazards in various industrial settings, they are not directly associated with the handling of radiographic sources. The primary concern with such sources remains the risk of ionizing radiation exposure.
