Abstract: The results of a determination of the concentration and dispersity of radioactive aerosols in the local zone of the Cover in spring 2011 are presented. Aside from aerosols – products of the accident at the Chernobyl NPP in 1986, technogenic 131,132I, 132Te, and 134,136Cs contained in the emissions from the damaged units of the Fukushima-1 NPP and spreading in the Northern Hemisphere were found. It was determined that technogenic 131I and 134Cs and naturally occurring 7Be and 210Pb were present on the carriers of similar activity median aerodynamic diameter <1 μm. It is shown that the content of radioactive aerosols – products of the accident at the Fukushima-1 NPP did not exceed the admissible concentration of radionuclides in air for the population and did not make a substantial additional contribution to the dose load to workers at the site of the Cover.

Radiocaesium Activity Concentrations in Potatoes in Croatia after the Chernobyl Accident and Dose Assessment

Title: Radiocaesium Activity Concentrations in Potatoes in Croatia after the Chernobyl Accident and Dose Assessment

Author: Franic, Z. / Petrinec, B. / Marovic, G. / Franic, Z.

Keywords: potatoes; 137 Cs; 134 Cs; transfer factor; Chernobyl accident; mathematical model; dose

Abstract: Systematic investigations of 137Cs and 134Cs activity concentrations in potatoes (Solanum tuberosum) for the post-Chernobyl period (1986-2005) in the Republic of Croatia are summarized. The correlation between 137Cs activity concentrations in fallout and potatoes, has been found to be very good, the correlation coefficient being r2=0.88 with P(t) < 0.001 for 18 degrees of freedom. As the radiocaesium levels in potatoes decreased exponentially, the mean residence time of 137Cs in potatoes was estimated by fitting the measured activity concentrations to the exponential curve. The mean residence time was found to be 6.8 +/- 1.1 years, the standard deviation being estimated by the Monte Carlo simulations.

Keywords: Chernobyl nuclear power plant, Internal irradiation dose, Whole body counter, 137Cs

Abstract: During the Chernobyl Nuclear Power Plant (CNPP) accident on 26 April 1986, large amounts of radionuclides were released and spread to vast areas. Inhabitants residing around CNPP have been exposed to external and internal irradiation due to the long half-life of 137Cs (30 years). In this study, we screened for internal whole-body 137Cs concentration using a whole-body counter in the Zhitomir state of Ukraine. The total number of participants was 144,972 (96,149 females and 48,823 males). The median body burden of 137Cs per body weight decreased from 1996 to 2008. In particular, after 2003, more than half of subjects had internal exposure doses below the detectable level.

Abstract: To evaluate current environmental contamination and contributions from internal and external exposure due to the accident at the Chernobyl Nuclear Power Plant (CNPP) and nuclear tests at the Semipalatinsk Nuclear Testing Site (SNTS), concentrations of artificial radionuclides in edible mushrooms, soils and stones from each area were analyzed by gamma spectrometry. Annual effective doses were calculated for each area from the cesium contamination. Calculated internal effective doses of 137Cs due to ingestion of mushrooms were 1.8 × 10–1 mSv/year (y) in Gomel city (around CNPP), 1.7 × 10–1 mSv/y in Korosten city (around CNPP), 2.8 × 10–4 mSv/y in Semipalatinsk city, and 1.3 × 10–4 mSv/y in Nagasaki.

Keywords: Chernobyl Soil, 129I, AMS, ICPMS, Iodine

Abstract: A large amount of radioiodine isotopes (mainly (131)I, t(1/2) = 8 days) was released from the accident at Chernobyl Nuclear Power Plant (CNPP) in April-May 1986. An increase in childhood-thyroid cancer in the contaminated areas in Belarus, Russia and the Ukraine was demonstrated to be caused by radioiodine released at the time of the accident. However, there is a lack of quantitative data on the (131)I levels in the local environment (e.g. air, plant, soil). At this point, a long-lived iodine isotope, (129)I (t(1/2) = 15.7 million years), also released with a certain ratio to (131)I from CNPP, could be used for estimating the (131)I levels in the environment.

Studies on the gamma radiation environment in Sweden with special reference to 137Cs

Title: Studies on the gamma radiation environment in Sweden with special reference to 137Cs

Author: Almgren, Sara

Reference: Göteborgs universitet, Department of Physics, 2008

Keywords: gamma radiation, caesium, 137Cs, deposition, migration, precipitation in situ, CDE, NWF, Chernobyl, soil sampling, field measurements, dose measurements, dose rate, TLD, natural radiation, kriging

Abstract: Gamma radiation in the environment today mainly originates from naturally occurring radionuclides, but anthropogenic radionuclides, such as 137Cs, contribute in some areas. In order to assess population exposure in case of fallout from nuclear weapons (NWF) or accidents, knowledge and monitoring of external gamma radiation and radionuclide concentrations in the environment is important. For this purpose 34 sampling sites were established in western Sweden and repeated soil sampling, field gamma spectrometry (in situ measurements), and dose rate measurements were performed. The variations in the activities between the different sampling occasions were found to be quite large. The naturally occurring radionuclides were the main source of outdoor dose rates. The uranium and thorium decay series contributed about equally to the total dose while the contribution from 40K was somewhat higher.

Keywords: International collaboration; Thyroid cancer; Public understanding; Nagasaki University; Radiation Effects Research Foundation

Abstract: This paper will describe my personal experience in the investigation of childhood thyroid cancer following the Chernobyl nuclear power plant accident. My experience started in 1987 when I was President of the Japanese Society of Nuclear Medicine and held a symposium on “Radiation and the Thyroid” where the health effects of the Chernobyl accident were reported by an expert from the European Thyroid Association (ETA). In 1990, I joined the IAEA project and the Chernobyl Sasakawa Health and Medical Cooperation Project, followed by the WHO/IPHECA Project, and the projects of the Ministry of Foreign Affairs, Japan. In 1992, I participated as a member of the European Community Commission, the Nagasaki Association for Hibakushas’ Medical Care (NASHIM), the Hiroshima International Council for Health Care of the Radiation-Exposed (HICARE), and finally as the Chairman of the Radiation Effects Research Foundation (RERF).

In addition to a description of the results of each project, the results of a scientific investigation on the health effects of the Chernobyl accident will be summarized and the gap between the scientific results and the public understanding will be discussed. Finally, the study themes to advance scientific knowledge for the benefit of humanity will be suggested.

Increase of Regional Total Cancer Incidence in North Sweden Due to the Chernobyl Accident?

Title: Increase of Regional Total Cancer Incidence in North Sweden Due to the Chernobyl Accident?

Author: Martin Tondel

Reference: [PDF-43K]May 2008

Keywords:

Abstract: In Europe concerns about the consequences of the Chernobyl accident have focused on childhood malignancies, especially leukaemia, assumed to have a short latency period after irradiation. Several studies have been performed outside the former Soviet Union, but none has shown any clear relationship with the fallout from the Chernobyl accident. However, children exposed during pregnancy have shown an increased risk of leukaemia in Greece, Germany and Ukraine, but not in Belarus. A recent study from Ukraine reports an increase in adult leukaemia after exposure from Chernobyl radiation. In Belarus, Ukraine and the western part of Russia, there has been a dramatic increase in thyroid cancer incidence in children related to the accident. In other parts of Europe a similar increase in thyroid cancer has been seen in adults…
