DAILY Release From Fukushima Of 100+ Quadrillion Bq Of Cesium-137 Early On In Crisis – Chernobyl TOTAL Release Was ~70 Quadrillion Bq Of Cesium-137


Fukushima Now Equal To 50 Plus Chernobyls & 3,000 Billion Lethal Doses Of Radiation (Veterans Today, May 28, 2011):

“Three thousand billion (3,000,000,000,000) Lethal Doses of Radiation means there are 429 Lethal Doses chasing each and every one of us on the planet, to put it in a nutshell.”

Russian Study: Fukushima released 100 quadrillion becquerels of cesium into atmosphere… In just ONE day — About equal to Chernobyl’s total release

Study: Daily release from Fukushima of 100+ Quadrillion becquerels of cesium-137 early on in crisis “seems reasonable” — Chernobyl total release was ~70 Quadrillion Bq of cs-137 (ENENews, Feb 19, 2014):

Comparison between modelling and measurement of marine dispersion, environmental half-time and 137Cs inventories after the Fukushima Daiichi accident (pdf), January 2014: The 137Cs total atmospheric source term varies […] (Schöppner et al. 2012) implies a much higher activity (1,000 – 10,000 PBq*) in the total inventory of radionuclides released. […]

*PBq = petabecquerel = quadrillion becquerels

Michael Schöppner, University of Roma Tre, Doctoral School of Mathematics and Physics (pdf), 2012: […] using the Fukushima nuclear accident as an example it is demonstrated that it is possible to reconstruct a source term of known location. […] This is done exemplary on the basis of the 2011 Fukushima nuclear accident. […] Due to the radioactive and unstable environment on-site of the NPP no reliable assessment of the emissions could have been done. […] Fukushima source term can be approximated by usage of ATM [atmospheric transport modelling]. […] although the reconstructed source suggests higher emissions than presented in other publications, the derived time dependent characteristics are in reasonable agreement. […] the comparison shows similar features in the source terms from various isotopes and stations. […] the problem of source term reconstruction has been reduced to a system of linear equations.

Journal of Environmental Radioactivity, Michael Schöppner, et al., December 2012 (emphasis added):  […] the real source-term at the FD-NPP emitted fewer particles in the case of 137Cs than assumed in the worst case scenario. Based on these results a source term of 10^17 – 10^18 Bq/day [100 PBq/day – 1,000 PBq/day] seems reasonable. For 131I, however, these first results suggest a source term not too different from the worst case scenario of 10^19 Bq/day [10,000 PBq/day]. […] The fact that the two remote stations, RN79 [Hawaii] and RN70 [Sacramento, CA], suggest a lower source term than the worst case estimation, where the closest station, RN38 [Takasaki, Japan], does not [… This may indicate] unaccounted regional meteorological conditions. […] The presented simulations with improved settings, i.e. dry and wet deposition, resulted in a better estimation of the source-term than previously reported (Plastino et al., 2011). The scenario assuming a worst case situation suggests generally higher source-terms, which are in reasonable agreement with the reported values (IAEA, 2011). For 137Cs emissions of 10^17 – 10^18 Bq/day [100 PBq/day – 1,000 PBq/day] seem to be reasonable, while for 131I even continuous emissions of 10^19 Bq/day [10,000 PBq/day] could be possible.

  1. I just watched “On the Beach” a dark and hopeless story of nuclear destruction released in 1959. For anyone who has not seen it, I recommend it highly.
    The denial is amazingly similar to what we are seeing today….only now it is real life. In the movie, it was nuclear war, the reality is much worse. It is going to destroy our lives, and most people ignore the beast regardless it is already in our food, water, oceans and air.
    I am appalled the US is siding with these bastards. In my eyes, it is pure genocide. There is no excuse for this corporate greed, yet they plan to change their name and go on selling nuclear plants.
    We have idiots in power, and they are blind to what is happening…….they only see more money for them, their greed has totally enveloped them……they see only what they want.
    Food chain is broken, the Pacific is dying, our water and soil permanently destroyed. Yet, the idiots in power continue to act as if nothing has changed.
    Good story.

  2. Obama and Kerry say its global warming..Thats the real threat. Fukushma is being monitored, and all the left coast radiation detectors equipment is turned off.

    Maybe he thinks this will bring the 12th imam.
