Abstract: The impact of the Fukushima nuclear accident in north–western Greece was assessed through an environmental monitoring programme activated by the Nuclear Physics Laboratory of the University of Ioannina. Measurements of 131I were carried out in atmospheric particulate, ovine milk and grass samples. In daily aerosol samplings, radioiodine was first detected on March 25–26, 2011 and reached maximum levels, up to 294 μBq m−3, between April 2 and April 4, 2011. In ovine milk samples, 131I concentrations ranged from 2.0 to 2.7 Bq L−1 between April 2 and April 6, 2011, while an average activity of 2.7 Bq kg−1 was measured in grass samples on April 4, 2011. The 134,137Cs isotopes were below detection limits in all samples and could only be determined in the air, by analysis of multiple daily filters. A maximum average activity concentration of 137Cs amounting to 24 μBq m−3 was measured during the period from April 5 to April 9, 2011, with the 134Cs/137Cs activity ratio being close to unity. Activity concentrations were consistent with measurements conducted in other parts of the country and were well below those reported in May 1986 after the Chernobyl accident. The committed effective dose to the whole body and to the thyroid gland from inhalation of 131I was estimated for the adult and infant population and was found to be of no concern for the public health.

Title: Preliminary evaluation of the impact of the Chernobyl radiological contamination on the frequency of central nervous system malformations in 18 regions of Europe
Reference: Paediatric and Perinatal Epidemiology, Volume 2, Issue 3, pages 253–264, July 1988
DOI: 10.1111/j.1365-3016.1988.tb00216.x
Keywords: human breast milk; Iodine-131; radioiodine
Abstract: The teratological impact of radiological contamination from the Chernobyl accident was evaluated in relation to central nervous system and eye defects in 18 regional registries in nine countries of Western Europe. Six classes of anomaly were analysed: neural tube defects, arhinencephaly, microcephaly and brain reduction, hydrocephaly, anophthalmos and microphthalmos, and congenital cataract. Conceptions up to 31 August 1986 were grouped into two exposure cohorts. In cohort A the sensitive period of fetal development to radiation fell wholly or partly between 1 May and 30 June 1986. Cohort B included all cases exposed during their sensitive period on or after 1 May 1986. Observed frequencies of the six classes of anomaly in the exposed cohorts were compared with expected frequencies calculated from baseline rates for the period 1980–1985. The only significant increase was neural tube defects in Odense, Denmark (four cases observed in cohort A where 0.9 were expected). The results of the study do not show a general increase in the frequency of malformations in the countries of Western Europe. The evidence presented indicates that, in the regions studied, termination of pregnancies or invasive prenatal diagnostic examinations were not justified for women exposed during pregnancy.

Keywords: human breast milk; Iodine-131; nuclear power plant accident; radioiodine
Abstract: Environmental pollution with radioiodine (iodine-131, 131I) occurred after an accident at the Fukushima nuclear power plant (FNP) on March 11, 2011, in Japan. Whether environmental pollution with 131I can contaminate human breast milk has not been documented. The 131I content was determined in 126 breast milk samples from 119 volunteer lactating women residing within 250 km of the FNP, between April 24 and May 31, 2011. The degree of environmental pollution was determined based on the data released by the Japanese government.

Title: Transfer of radiocaesium in sensitive agricultural environments after the Chernobyl fallout in Sweden: III. County of Västernorrland

Abstract: In 1986 a large number of farms in the Chernobyl-affected area in the county of Västernorrland in northern Sweden were investigated for radiocaesium transfer to grass and cereal grain. The soil surface layer (0–5 cm) in 1986 and the crop products in 1986–1996 were analysed. The aim was to study the impact of soil and crop rotation on sensitivity of 137Cs transfer in a short and long term perspective. In the fallout year 1986 the transfer to grass was usually much higher than to cereal grain. In this year the transfer to grass was usually much higher in the first cut rather than the second cut. The reduction in transfer with year was large but variable with site and with crop sequence. Ploughing was effective in decreasing the transfer of 137Cs to crops. On arable sites in 1986 the transfer to cereal straw was larger at late stem elongation (LSE) than at the maturing stage. Unexpectedly, there was no clear relationship between transfer of 137Cs to the crops and any of the soil characteristics. In 1986 the transfer of 131I to grass and cereals was also investigated on some of the farms. The results are compared with the transfer of 137Cs, 2 months after the Chernobyl fallout.

Abstract: For the period 1998–2002, in the framework of the Ukraine–USA Thyroid Project, medical screening examinations have been conducted to subjects who were aged 0 to 18 years at the time of the Chernobyl accident. These were residents of eight districts, from Kyiv, Chernihiv, and Zhytomyr regions of the Ukraine, having been most affected following the Chernobyl accident, and having received within several weeks after the accident direct measurements of thyroid doses of gamma radiation. For the period 1998–2000, 13227 cohort subjects have undergone screening, and in 2001–2002, a repeat screening was performed. As a result of screening, 64 cases of thyroid carcinoma have been identified, including 43 cases after the first screening and 21 cases after the second screening….

Keywords: radiation; thyroid cancer; thyroid oncogenes; radioiodine; Chernobyl cancer
Abstract: While a great deal is known about the relationship between external radiation exposure and thyroid cancer, much less is known about the oncogenic effects of internal radiation exposure from isotopes of iodine. The accident at the Chernobyl nuclear power plant released massive quantities of radioiodine isotopes into the atmosphere. The large number of ensuing thyroid cancers in exposed children leaves little doubt that these malignancies have occurred as a result of the accident. However, carefully planned epidemiological studies are needed to confirm that these are due predominantly to I-131 exposure, to determine the dose-response relationship, to monitor for continuing effects and to evaluate other contributing factors. Preliminary evidence indicates that there is a distinct pattern of somatic genetic changes in the thyroid cancers from the Chernobyl area.
