Radioactivity from Fukushima nuclear accident detected in Lisbon,
Portugal http://sciencealerts.com/stories/2015645/Radioactivity_from_Fukushima_nuclear_accident_detected_in_Lisbon_Portugal.html#.UGX5NpjA9
The radioactivity released from the Fukushima Dai-ichi nuclear
accident was transported around the globe by atmospheric processes.
Several artificial radionuclides were detected and measured in
aerosols and atmospheric surface depositions in the Lisbon area during
late March and early April 201The highest concentrations measured in
aerosols were those of particulate 131I, 1.39 ± 0.08 mBq m-3.
Cesium-134, 137Cs and 132Te were also determined but at lower
concentrations. The total atmospheric depositions on the ground were
higher on the first week of April with values for 131I, 134Cs, and
137Cs of 0.92 ± 0.11, 0.59 ± 0.06, and 0.62 ± 0.12 Bq m-2,
respectively. The four artificial radionuclides measurable, 131I,
132Te 134Cs, and 137Cs, caused little radiation exposure to the
members of the public, that was five orders of magnitude lower than
the ionizing radiation effective dose limits for members of the public
for one year (1 mSv y-1). Radionuclides from Fukushima nuclear
accident were measured in aerosols at Lisbon, Portugal. Cesium-137 and
iodine-131 were measured in atmospheric precipitation. Radiation dose
to members of the public was much lower than dose limit of 1 mSv/y.
