—During the examination of a patient with a diffuse goiter, a technetium Tc 99m scan was done. After the procedure was performed, the patient returned to her work at a nuclear plant. To her surprise, a variety of alarm lights and sirens were activated when she walked through a door. Only after she had been undressed, showered, and "decontaminated" was she able to get across to the plant physician that she had just had a thyroid scan performed. Although there have been no long-term residual effects of this "complication," it shows the need of obtaining a previous occupational history before performing any outpatient nuclear medicine procedures.
