Collect specimens

Following a radiological incident, collect urine samples for each person involved. View this flowchart for directions on how to collect urine samples from potentially exposed individuals: CDC Specimen-Collection Protocol for a Radiological/Nuclear Incident

Package and ship specimens

  • After collecting the samples, package and ship them to the appropriate laboratory destination based on your state's radiological terrorism comprehensive response plan. If you are instructed to ship your specimen to the CDC laboratory, follow these instructions.
  • CDC also has comprehensive instructions for collecting, labeling, packaging, and shipping specimen samples collected from people who may have been internally contaminated with radioactive materials.
