Possibility of losing California, Southern Hemisphere August 2018 Background Level Re
#1
USA

13th August 2018 - San Onofre Nuclear Waste Accident Near Miss

Extracts:


While working at the plant in his capacity as a safety professional, Fritch observed first hand a near catastrophe. On 3 August 2018, a 100-ton canister filled with highly radioactive nuclear waste was being “downloaded” into a temporary transport carrier to be moved a few hundred yards from inside the plant to a storage silo buried near the world-famous San Onofre beach. As the thin-walled canister was being lowered into the transport cask, it snagged on a guide ledge four feet from the top. Crane operators were unaware that the canister had stopped descending and the rigging went completely slack, leaving the full weight of the heavy canister perched on that ledge by about a quarter-inch.

Had the ledge not held for the hour or more it took workers to realize and address the error, the thin-walled canister of highly toxic nuclear waste would have fallen 18 feet to the ground below.

22st August 2018 - San Onofre SOS! Update on Accident Near-Miss w/Donna Gilmore + New Int’l Nuke News Source – Linda Pentz Gunter NH #374 (Radio Interview)

Quote: "A possibility of losing California and then some". (Interview starts around 20 minutes in)

Extract:

San Onofre Safety‘s Donna Gilmore tells what she tried to say to Southern California Edison at the August 9 Community EnRagement, uh, Engagement Panel when the “experts” shouted her down.  More scary information on how the nuclear industry is playing loose and fast with highly radioactive nuclear reactor waste, as well as Southern California’s future.

This short animation of Northern and Southern Hemisphere air circulation, shows why we can get detections so far south.





Since the Fukushima Nuclear Catastrophe, the long term August month averages are showing a gradual increase background levels.

Could you maybe post a chart with the pre-Fukushima averages.  Was interested to see if pre-Fukushima was also increasing or more stable.  I recall seeing the data before, just can't find it now.  Not sure how far back you had data.  Was there an admixture from the northern hemisphere to the southern hemisphere before as well?  Was it fairly constant?  If you had data back far enough, would you see the same kind of increase in background from Chernobyl as the after Fuku yearly averages?  It looks like something in 2017 spurted a doubling in the percentages.

Here is the chart you are after.

Be aware that the GammaScout logging Geiger counter that was data logging prior to Fukushima was set to log once a week. So the logged data for the four years prior to Fukushima is based on once a week sampling.

In late December 2011 and into January 2012 data logging was changed to 10 minute data logging. and after the radioactive cloud detection in early January 2012 to  60 second data logging. All the charts sense then has been based 60 second logging.

Thanks Vital1, that's the chart.    

pre-Fuku year average 0.10 uSvhr
after Fuku year average  about 0.12 uSvhr

An average 0.02 increase after the huge 2011 three meltdown Fuku release mixed into the air in the Northern Hemisphere, spilling into the Southern Hemisphere.  It looked to be leveling off as might be expected after five years of rainouts.  My concern was the increase starting 2016; like another large release from another meltdown might have occurred in the Northern Hemisphere.  

I could try to blame Dai-ichi for the increases, they opened r1 and fished a broken crane out of r3's SFP.  There was sparking and fogging like in the early years.  We found sparks on TBS-JNN and they stopped broadcasting that camera outside of Japan.  The censorship leaves me in the dark.  Was the decommissioning work enough to cause the increase or did a different player have an accident?  MVB has the same problem analyzing EURDEP readings; more detection hints but censorship of the data so that nothing can be proven.  I don't think the nuke industry will want another nuclear meltdown to make the headlines.  It'll be interesting to see if the Caloundra background level increases continue.  Thanks for sharing your data.

Yes, I have had the same experience with the censorship of the monitoring systems. MVB and I have seen detection increases a number of times since Fukushima that suggested a number of serious nuclear events went down but were covered up.

Some may have been related to events at Fukushima, but the others where not.

I have re-calibrated the graph to reflect the ECRR dose coefficient of Fukushima nuclear fallout which they give as approximately 600x higher than the ICRP standard.  Its easier to see the increase in hazard after the Fukushima accident.

This is a modification of Vital1's graph in post 3.  Can you make out the difference?

The graph...I made the following assumptions

1. The ECRR is approximately correct about the dose multiplier for Fukushima fallout

2. that the baseline before fukushima consisted primarily of non fallout background radiation.  

3. the increase is due totally to fallout

of course, there are so many factors and unknowns that the graph is not something to be called accurate but rather indicative. 
The Fukushima fallout consists of a large percentage of micro particles. These may be more biologically damaging, for a given measured dose, then dispersed Cs137 and other 'free' fission products.

On the other hand, if the pre fukushima levels consisted entirely of non anthropogenic radiation, the pre Fuku danger may be even less then it might seem. on the graph. Several studies suggest that background dose may be a biological optimum

Nuke fallout everywhere.  Background isnt background radiation. Secret, illegal nuclear bomb test off South Africa by Israel in 1979 contaminated sheep (and other animals) thyroids with radioactive iodine in Australia

Taking an instrument reading is pretty straight forward, it's the interpretation of the results that often come into question.

0.02 uSvhr doesn't seem to be much of an increase but it wouldn't be there without the man-made inputs. I agree with your basic assumptions and your indicative chart.

Vital1's station in the Southern Hemisphere gives us a unique view of what a natural background is without as much of the man-made nuclear isotopes having been added. Some testing has occurred in the Southern Hemisphere but not nearly as much as has been released in the Northern Hemisphere. Vital1 has observed increases in the Southern Hemisphere background spilling in from the Northern Hemisphere as the air mass slowly mixes between the two halves. First, that should make everyone guess how much have they have added in the Northern Hemisphere. Second, that maybe we were seeing a signal of the Fukushima release. If so, what are these newer increases?
