The urgent need for protective shielding for personnel who administer radiopharmaceuticals

Traditional practices to administer radiopharmaceuticals to patients for positron emission tomography 
involve exposure to ionizing radiation. Techniques developed to reduce radiation exposure to personnel who 
inject radiopharmaceuticals may be considered unnecessary by experienced nuclear medicine personnel. A 
69-year-old male nuclear medicine attending developed bilateral cataracts after 18 years of regular 
administration of radiopharmaceuticals. Although protective shielding was not used for the first 14 years of 
his practice, it was uniformly applied for the subsequent 4 years. Nuclear medicine personnel are advised to 
use protective shielding and to design work improvement procedures to minimize radiation exposure for 
staff and patients.
