The learner is encouraged to consult with nursing and allied health experts in the clinical area for additional training needs. The purpose of this independent study module is to review basic radiation training knowledge needed to provide a safe level of care in the clinical setting. The intended audience includes licensed and unlicensed personnel who are familiar with radiation training. Identify three principles of external radiation protection. Distance can be employed to provide complete protection from charged particles by simply moving beyond the range of the particles.
Exposure decreases with the square of the distance.
The denser and thicker the shield, the lower the radiation dose received. Essential personnel remaining in the room must wear a lead apron. When a patient must be restrained, mechanical restraints should be used whenever possible rather than having an individual hold the patient. Individual must wear lead apron and gloves. No part of the individual's body should be in the direct path of the x-ray beam.
