This effect is particularly dramatic for other medical personnel whose radiation exposure is low if they are properly positioned at distances greater than 8 feet from the patient. Physicians should also make full use of personal shielding in using lead aprons, thyroid collars and leaded eye protection. Lead aprons and thyroid shields should be fluoroscoped at least annually to check for cracks and holes. Table side drapes and ceiling suspended leaded acrylic shields are important components of radiation protection. C-arm position changes necessitate repositioning the ceiling mounted shield to maintain its effectiveness.
Designs vary for the table side drapes.
Some are available with a hinge to allow moving a section of the drape to maintain shielding effectiveness when the X-ray tube position is changed. The cumulative effects of these precautions markedly reduce exposure to radiosensitive tissues and should limit annual radiation doses to levels well below published safety guidelines.
