Keywords: satellite, Landsat, radioactive fallout

Abstract: Regarding the Chernobyl Nuclear disaster; NOAA/AVHRR and Salyut/KATK-140 imageries show the land cover condition of the wide area around the nuclear complex. Landsat TM image acquired on 29 April 1986 informs us the thermal condition of the exploded reactor and suggests the heavy deposition area. Landsat TM image on 26 April 1985, before the accident, shows the normally operated condition in the reservoir. Also Spot HRV 10 meter resolution image exhibits the planimetric configuration of the complex.

Abstract: [The nuclear accident occurred at Fukushima Dai-ichi Nuclear Power Plant (NPP) (March 11, 2011) similarly to the accident at the Chernobyl NPP (April 26, 1986) is related to the level 7 of the INES. It is of interest to make an analysis of the radionuclide composition of the fallout following both accidents. The results of the spectrometric measurements were used in the following comparative analysis. …]

Territory contamination with the radionuclides representing the fuel component of Chernobyl fallout

Title: Territory contamination with the radionuclides representing the fuel component of Chernobyl fallout

Reference: Science of The Total Environment, Volume 317, Issues 1–3, 30 December 2003, Pages 105-119

DOI: http://dx.doi.org/10.1016/S0048-9697(03)00336-X

Keywords: Chernobyl accident; Terrestrial density of contamination; Plutonium; Radioactive fallout; Fuel particles

Abstract: The data obtained through a series of experiments were used to specify the correlation of activities of the fuel component radionuclides of Chernobyl fallout and to create the maps of the 30-km Chernobyl zone terrestrial density of contamination with ¹⁵⁴Eu, ²³⁸Pu, ^239+240Pu and ²⁴¹Am (on 01.01.2000). In the year 2000, total inventories of the fuel component radionuclides in the upper 30-cm soil layer of the 30-km Chernobyl zone in Ukraine (outside the ChNPP industrial site, excluding the activity located in the radioactive waste storages and in the cooling pond) were estimated as: ⁹⁰Sr—7.7×10¹⁴ Bq; ¹³⁷Cs—2.8×10¹⁵ Bq; ¹⁵⁴Eu—1.4×10¹³ Bq; ²³⁸Pu—7.2×10¹² Bq; ^239+240Pu—1.5×10¹³ Bq; ²⁴¹Am—1.8×10¹³ Bq. These values correspond to 0.4–0.5% of their amounts in the ChNPP unit 4 at the moment of the accident. The current estimate is 3 times lower than the previous widely-cited estimates. Inventories of the fuel component radionuclides were also estimated in other objects within the 30-km zone and outside it. This allowed more accurate data to be obtained on the magnitude of a relative release of radionuclides in the fuel particles (FP) matrix during the Chernobyl accident outside the ChNPP industrial site. It amounts to 1.5±0.5% of these radionuclides in the reactor, which is 2 times lower than the previous estimates. Two-thirds of the radionuclides release in the FP was deposited on the territory of Ukraine.

Empirical scavenging coefficients of radioactive substances released from chernobyl

Title: Empirical scavenging coefficients of radioactive substances released from chernobyl

Author: Kirsti Jylhä

Reference: Atmospheric Environment. Part A. General Topics, Volume 25, Issue 2, 1991, Pages 263-270

DOI: http://dx.doi.org/10.1016/0960-1686(91)90297-K

Keywords: Chernobyl; radioactive fallout; wet scavenging coefficient; weather radar; Finland

Abstract: After the accident at the Chernobyl power plant on 26 April 1986, most parts of Europe were affected by the associated radiation pollution. In this paper the dependence of the precipitation scavenging coefficient λ (s⁻¹) on the rainfall rate R (mm h⁻¹) is studied on the basis of radioactivity and radar rainfall measurements in Southern Finland after the accident.
