Ct Patriot: I’m Just going to keep talking about Fuckushima, Until hopefully enough people realize this is a really really bad thing. Way worse than crossing the streams in Ghostbusters. And this is REAL! Does any one else care ?
Japan Researchers: Models show North America hit with ‘very high’ levels from Fukushima plume — Radioactive material in ocean off West Coast was up to 500 times more than expected
- FNPP1 accident widely dispersed radionuclides across the entire North Pacific region… simulation results in some area of the eastern North Pacific showed a tendency of underestimation against observed data… the simulation results in the eastern North Pacific [for 134Cs] were also lower than the measurement results. This tendency indicates that the actual abundance of 134Cs in the eastern North Pacific was higher… We attributed this tendency to an underestimation of the release rate in the initial source term… source term was estimated on the basis of environmental monitoring data on land. However, monitoring data in the ocean were not considered… accuracy of the initial source term [from March 12-14] was low… it was impossible to classify the volume of the amount released as a result of [Unit 3’s] explosion.
- Cesium-134 simulation with the new source term… the new source term increased the traffic transport of radionuclides to the east… the new release rates at all 18 terms increased… However, the simulation results [using new source term] in some areas of the eastern North Pacific remain underestimated.
Note: Rightmost point inside large oval in the graph above shows a calculated (i.e. estimated) Cs-134 level of below 2E-05 Bq/L (.02 Bq/m³). The observed CS-134 level exceeded 1E-02 Bq/L (10 Bq/m³) — 500+ times than estimated.
- The Science Council of Japan launched a model intercomparison project to review the capability of current numerical models to reproduce the transport of radioactive materials released to the environment as a result of the Fukushima Dai-ichi Nuclear Power Plant… results show relatively good agreement of the deposition pattern of 137Cs, indicating significant deposition of 137Cs over the northwestern Pacific up to the Aleutian Islands, and reaching to the western part of North America.
- 7:30 in — TY Tanaka, Japan Meteorological Agency: This map shows the horizontal distribution of cesium-137. As you can see, they show similar patterns of results from Fukushima power plant to the northwest Pacific Ocean and to the Aleutians. Some models reach very low North America — but some of them reach very high.
Study: Fukushima airborne plumes “caused significant deposition of radioactivity over North America” — Especially for West Coast and eastern U.S. — Around 13% of all radioactive iodine released into atmosphere was deposited over USA and Canada (MAP)
February 14th, 2014
European Commission, Science for Environment Policy News Alert (pdf): The 2011 nuclear accident at Fukushima, Japan, caused the release of large amounts of radionuclides (unstable atoms that produce radioactive emissions) to the atmosphere. Caesium and iodine radionuclides can negatively affect human health through the contamination of air, water, soil and agricultural products. The EU-funded study1 modelled the global spread of radionuclides of caesium and iodine from Fukushima in the atmosphere […] or iodine radionuclides […] meteorological conditions and convection promote more long-distance transport. This is because iodine does not dissolve as easily as caesium so it remains in a gaseous form and is redistributed by convection to the troposphere (lowest part of atmosphere) where the wind speed is greater and transports the iodine greater distances. The model results suggest that 12.7% of iodine radionuclides were deposited over the USA and Canada […] Approximately 50-60% was deposited locally in Japan.
Modelling the global atmospheric transport and deposition of radionuclides from the Fukushima Dai-ichi nuclear accident (pdf), 2013: […] meteorological conditions associated with convection and vertical mixing over the Pacific Ocean promote its longdistance transport so that it contributes to radioactivity deposition worldwide. Our model results suggest that the plumes that traversed the Pacific Ocean caused significant deposition of radioactivity over continental North America, in particular western USA, western Canada and eastern USA (>100 Bqm−2). Our model results also show substantial deposition of radionuclides in regions southwest of Japan, e.g., around the Philippines1. Two weeks after the accident, all operational CTBTO stations in the northern hemisphere had reported at least one 131I detection.
