[ RadSafe ] Release of radioactive particles from Fukushima claimed to be greater than from Chernobyl

[Roger Helbig]

The source in Korea looks genuine, but since it is in Nuclear-News, it
gives you cause to wonder if the alleged conclusion of the research is
sound.

Release of radioactive particles from Fukushima was in fact greater
than from Chernobyl

by Christina MacPherson

Gov't report reveals Fukushima radioactive release much larger than
Chernobyl -- Japan reactors could have emitted nearly four times as
much cesium-137

Korea Atomic Energy Research Institute, funded by the Korean
government, July 2014:

The Fukushima accident [led to a] release of huge radioactivity
It is reported... 4 times more radioactivity was released to the sea
than to the atmosphere
Best-estimate source term of 137Cs... released into the atmosphere, is about 4%
Best-estimate release fraction of the 137Cs inventory that flowed into
the sea...about 16%
Of the 4% inventory of 137Cs released into the atmosphere, only 0.8%
was deposited in the Japanese land and the other 3.2% was transported
to the sea or other areas
The inventory... available for release in the units 1-3... the time of
accident [was] 7.6 - 8.2 x 10^17 [760 - 820 quadrillion] Bq for 137Cs
Because of the geographic location of the nuclear power plant -- at the
beach of the Pacific Ocean... more than 80% of the radioactivity
released from the crippled reactors flowed into the sea

To determine the best estimate of the total 137Cs that was released
into the environment from Fukushima, the 137Cs release fraction (4%
atmosphere, 16% ocean) is multiplied by the 137Cs inventory for the 3
melted reactor cores (760 to 820 quadrillion Bq):

Ocean Release of 137Cs from Fukushima: 121.6 to 131.2 quadrillion Bq
(16% x 760 to 820 quadrillion Bq)
Atmospheric Release of 137Cs from Fukushima: 30.4 to 32.8 quadrillion
Bq (4% x 760 to 820 quadrillion Bq)
Total Release of 137Cs into the Environment from Fukushima: 152 to 164
quadrillion Bq
Total Release of 137Cs into the Environment from Chernobyl: 70 to 85
quadrillion Bq

However, the 137Cs inventory of 760 to 820 quadrillion Bq used by the
Korea Atomic Energy Research Institute is significantly lower than the
U.S. Department of Energy calculated:

DOE's Total 137Cs Inventory in Reactors 1-3: 1.3E+18 Bq (1,300 quadrillion Bq)
Ocean 137Cs Release from Fukushima: 208 quadrillion Bq (16% x 1,300 quadrillion)
Atmospheric 137Cs Release from Fukushima: 52 quadrillion Bq (4% x
1,300 quadrillion)
Total 137Cs Release into the Environment from Fukushima: 260 quadrillion Bq
Total 137Cs Release into the Environment from Chernobyl: 70 to 85 quadrillion Bq
