“…The activity concentrations of Th-232 from other sampling points remain below the mean Th-232 content (24 Bq/kg) for Estonian soils (Realo et al 1995). The low values of the activity concentrations of Th-232 were measured also in the samples from shore sands of the Lemme area (Koch 2006).…”

“…In 2011, the activity concentrations of U-238 (Ra-226) (Table 7) are below the mean concentration (26 Bq/kg) of U-238 (Ra-226) in Estonian soils (Realo et al 1995). The exceptions with higher U-238 (Ra-226) values were three samples: the sampling point 1a (115.48 Bq/kg) from depth of 12cm and (154.95 Bq/kg) from depth of 30 cm and sampling point 7a (29.82 Bq/kg).…”

As early as in the 1960s, extensive heavy-mineral concentrations containing zircon, monazite, and xenotime were discovered in the Lemme region of south-western Estonia. These concentrations contribute to the elevated radioactivity levels of the enclosing sediments. The near shore sands of the Litorina Sea contain up to 10-cm-thick interlayers with a heavy mineral content of up to 80%. These anomalous layers were formed during the transgressive phase and result from a complicated cross-and alongshore migration of sedimentary material, derived mainly from local Devonian bedrock. Radioactivity level in the study area is higher relative to the majority of the Devonian plateau. The Lemmeoja buried soil has 13 radiocarbon dates in an area of renewed interest for the investigation of the Baltic Sea history.

“…Dose evaluation for Belarus, Ukraine and the Russian Federation made use of detailed information provided by local experts or published in UNSCEAR and the UN Chernobyl Forum Report 1, 29. For less affected European countries, information was either obtained from local experts or authorities (Bulgaria, Czech Republic, Finland, Lithuania, and Switzerland) or from relevant publications 30, 31, 32, 33, 34, 35, 36, 37, 38. Data on 137 Cs deposition density and time‐integrated activity of 131 I and 137 Cs in foodstuffs in the first year after the accident were available in the Atlas on 137 Cs Deposition in Europe 22 and in the UNSCEAR 1988 report,21 respectively.…”

The Chernobyl accident, which occurred April 26, 1986, resulted in a large release of radionuclides, which were deposited over a very wide area, particularly in Europe. Although an increased risk of thyroid cancer in exposed children has been clearly demonstrated in the most contaminated regions, the impact of the accident on the risk of other cancers as well as elsewhere in Europe is less clear. The objective of the present study was to evaluate the human cancer burden in Europe as a whole from radioactive fallout from the accident. Average country-and region-specific whole-body and thyroid doses from Chernobyl were estimated using new dosimetric models and radiological data. Numbers of cancer cases and deaths possibly attributable to radiation from Chernobyl were estimated, applying state-ofthe-art risk models derived from studies of other irradiated populations. Simultaneously, trends in cancer incidence and mortality were examined over time and by dose level. The risk projections suggest that by now Chernobyl may have caused about 1,000 cases of thyroid cancer and 4,000 cases of other cancers in Europe, representing about 0.01% of all incident cancers since the accident. Models predict that by 2065 about 16,000 (95% UI 3,400-72,000) cases of thyroid cancer and 25,000 (95% UI 11,000-59,000) cases of other cancers may be expected due to radiation from the accident, whereas several hundred million cancer cases are expected from other causes. Although these estimates are subject to considerable uncertainty, they provide an indication of the order of magnitude of the possible impact of the Chernobyl accident. It is unlikely that the cancer burden from the largest radiological accident to date could be detected by monitoring national cancer statistics. Indeed, results of analyses of time trends in cancer incidence and mortality in Europe do not, at present, indicate any increase in cancer rates-other than of thyroid cancer in the most contaminated regions-that can be clearly attributed to radiation from the Chernobyl accident.

“…Local experts provided dose estimates for Belarus, Ukraine and the Russian Federation, where extensive work has been undertaken developing and validating methods for dose reconstruction (9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23) . For less affected European countries, information on country-specific radiation data and dose estimates was either obtained from local experts: Bulgaria, the Czech Republic, Finland, Lithuania and Switzerland; and/or from published data: Austria (24)(25)(26)(27)(28) , Belgium (29) , Bulgaria (30) , Croatia (31,32) , the Czech Republic (33,34) , Estonia (35) , Finland (36) , France (37) , Greece (38,39) , Hungary (40) , Italy (41,42) , Lithuania (43,44) , Norway (45,46) , Serbia and Montenegro (47) , Slovakia (48,49) , Sweden (50) , Switzerland (51) and the United Kingdom (52,53) .…”

On the occasion of the 20th anniversary of the Chernobyl accident an attempt has been made to evaluate the impact of the Chernobyl accident on the global burden of human cancer in Europe. This required the estimation of radiation doses in each of the 40 European countries. Dose estimation was based on the analysis and compilation of data either published in the scientific literature or provided by local experts. Considerable variability has been observed in exposure levels among the European populations. The average individual doses to the thyroid from the intake of 131 I for children aged 1 y were found to vary from $0.01 mGy in Portugal up to 750 mGy in Gomel Oblast (Belarus). Thyroid doses to adults were consistently lower than the doses received by young children. The average individual effective doses from external exposure and ingestion of long-lived radiocaesium accrued in the period 1986-2005 varied from $0 in Portugal to $10 mSv in Gomel Oblast (Belarus) and Bryansk Oblast (Russia). The uncertainties in the dose estimates were subjectively estimated on the basis of the availability and reliability of the radiation data that were used for dose reconstruction in each country.
