Radiation exposure and the risk of pediatric thyroid cancer.

Miyakawa M - Clin Pediatr Endocrinol (2014)

Bottom Line: It has been more than three years since the unprecedentedly massive earthquake and tsunami struck eastern Japan on March 11, 2011, and the large accident occurred at the Fukushima Daiichi Nuclear Power Plant.As of September 2013, 59 children had been diagnosed with thyroid cancer by fine-needle aspiration cytology, and 34 children had been treated surgically and ultimately diagnosed with papillary thyroid cancer.Here, I would like to describe the characteristics of pediatric thyroid cancer and typical thyroid images obtained by ultrasonography.

ABSTRACT
It has been more than three years since the unprecedentedly massive earthquake and tsunami struck eastern Japan on March 11, 2011, and the large accident occurred at the Fukushima Daiichi Nuclear Power Plant. To investigate the influence of radiation exposure, thyroid ultrasonography has been provided preliminarily for 360,000 children who lived in Fukushima Prefecture at the time of the accident. As of September 2013, 59 children had been diagnosed with thyroid cancer by fine-needle aspiration cytology, and 34 children had been treated surgically and ultimately diagnosed with papillary thyroid cancer. Here, I would like to describe the characteristics of pediatric thyroid cancer and typical thyroid images obtained by ultrasonography.

Mentions: The average background radiation in Japan is approximately 1.4 millisieverts (mSv) peryear. The upper radiation dose limit for radiation workers to prevent injury from radiationis 20 mSv. According to comprehensive examinations based on previous epidemiologic studiesand research results, it is generally concluded that no radiation doses below the limit haveany negative impact on human health. Even though it is said that chromosomal abnormalitiesappear in the most sensitive human health areas, such abnormalities have not been observedwith a radiation dose of 100 mSv or less. As shown by the radiation exposure doses shown inFig. 1Fig. 1.
