Radiation measurements and radioecological aspects of fallout from the cherbonyl reactor accident

Precipitation scavenging of 7Be and 137Cs radionuclides in air

“…Heavy rainfall, coincident with the passage of radioactive cloud over Greece on the 5th, 6th and 10th May 1986, caused local highly-radioactive deposits of 137 Cs, as high as 24 kBq m ÿ2 (Papastefanou et al, 1988).…”

The Chernobyl Effect at Japanese Northeast Pacific Coastal Area

“…They pointed out that in the stratosphere the activities at 15 km were about 1 to 6% of the ground level values. Papastefanou et al [5] suggest the presence of 103 Ru in the upper tropopause or low stratosphere from the data of rainfall on November 1986. From these results, on a timescale of several months, the remarkable increase of radioruthenium to 137 Cs ratios observed in this study indicates the differences of distribution and behaviour of these nuclides.…”

Cesium-137 Concentrations in Sediments and Aquatic Plants from the Pinios River, Thessalia (Central Greece)

“…The total release of fission products (ignoring inert radioactive gases) was estimated to be 1.85×10 18 Bq (IAEA 2006). The concentration of 137 Cs in the air was 1.80 Bq/m 3 , while the deposition in Thermaikos gulf, into which the Pinios river flows, showed the highest 137 Cs values (20-40 kBq m −2 ) when compared to all the other areas of the Aegean sea (Hennies 1986;Kritidis et al 1986;Papastefanou et al 1988;Kritidis and Florou 1990;Florou and Kritidis 1994;Florou 1996;Sawidis et al 2003;Sawidis et al 2010). The aim of the present study is to evaluate the spatial distribution of 137 Cs along the River Pinios, including its tributaries, and to enhance the knowledge about present activity concentrations.…”
