Which of the following should be limited to minimize radiation exposure to caregivers?

Limiting the time spent at the bedside is crucial for minimizing radiation exposure to caregivers. The principle of radiation protection emphasizes reducing exposure in three main ways: time, distance, and shielding. When caregivers reduce the time spent near a radiation source, they significantly decrease their overall exposure to radiation. The longer the caregiver is in proximity to the patient receiving radiation, the higher the potential dose they may absorb. Therefore, it is essential for caregivers to limit their time in such situations to enhance safety.

While distance and personal protective equipment also play important roles in radiation safety, they are secondary to the time factor in the context of this question. Increasing distance from a radiation source effectively reduces exposure, and personal protective equipment can provide a barrier against radiation; however, managing the time spent near the source directly correlates with reducing exposure more instantly and effectively. Documentation of care, while important for various reasons, does not have a direct impact on radiation exposure levels. Thus, focusing on minimizing time spent at the bedside is the most effective way to protect caregivers from radiation.
