Chernobyl, 10 Years After: Health Consequences

“…Nonetheless the information about children younger than 15 years is limited. The carcinogenicity of iodine-131 has been shown in animals, particularly among rats and mice (87,88). Some experimental studies suggest that malignant thyroid tumors can be induced four to 10 times less effectively with iodine-131 than with x-rays, although another study could not replicate this result (89).…”

“…Furthermore, the tumors observed are mainly invasive and fast-growing (111). It is now generally agreed that the increase in thyroid cancers observed among children and adolescents in the zones exposed to Chernobyl fallout is real (87,(111)(112)(113). Conversely, the increase observed among Belarussian adults is more likely to result from more intensive screening because of a relatively high prevalence of occult carcinomas in adults.…”
