“Latency Period of Benign and Malignant Thyroid Tumors

Although some sporadic tumors unrelated to radiation may be included among our patients, the shortest latency period for both benign and malignant tumors was 1 year as occurred in 3 patients, whereas the longest time was 69 and 58 years, respectively.”

Abstract

“The incidence of thyroid cancer in children increased dramatically in the territories affected by the Chernobyl nuclear accident; this increase is probably attributable to (131)I and other short-lived isotopes of iodine released into the environment. There was a broad range of latency periods in children who developed thyroid cancer; some periods were less than 5 years.”

“2.5 years, based on low estimates used for lifetime risk modeling of low-level ionizing radiation studies”, pdf page 1.

Why aren’t journalists asking the right questions?
