Radiotoxicity of iodine 131
The radioactive toxicity of iodine 131 is measured by an ‘ingestion dose conversion factor’ which allows to calculate the effective dose resulting from the ingestion of a given activity of a radioelement. Ingested Iodine-131 is dangerous because it primarily affects the thyroid gland that plays a fundamental role in childhood development. Radioactive iodine toxicity varies greatly with age, with toddlers, young children and adolescents being far more sensitive than adults.
