Effects of the Chernobyl disaster smaller thyroid glands compared to adults and have a different dosage response after the ingestion of iodine-131. A cohort study conducted in 2013 discovered a similar trend between age and dosage response. The cohort was composed of 12,000 participants, all of which were exposed to the radiation in Belarus and reported to be under the age of 18 at the time of the exposure. Studying the populations that were exposed to radiation after the Chernobyl accident has provided important data linking exposure to radiation and the future development of cancer. Cases of pediatric thyroid cancer, likely caused by absorption of
