20th March 2019 - As fears linger, Fukushima rice rebounds under anonymity

Extracts:

“There is high demand for industrial use rice from Fukushima Prefecture, which is cheap for its taste,” one distributor said.

Industrial use rice often only carries a “domestic” label with no mention of the production area.

Comment:

This lack of labeling on industrial rice makes it very difficult to determine what rice sold in Japan is from the Fukushima area. This rice could end up anywhere in the food processing industry. Below is a link to a very informative, 10 min video. It discusses the serious health effects, very small amounts of Cesium-137 consumed in food products, can do to children. Even if the detected Cesium level was low, and below the Japanese safety level of 100 Bq/kg, it is still way too high for children to consume!

Most western governments around the world raised the acceptable Cesium-137 safety levels to ridiculous amounts after Fukushima. They raised the level by twenty to thirty times, to 1200 Bq/kg. This shows how bogus these government set safety levels really are. They just change the acceptable level to whatever suits them at the time, to support the nuclear industry!

Southern Hemisphere March 2019 Background Level Report

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

March 2019 Report.

We finally received around 300mm of rain in March, decent rain after an exceptionally dry period.

Towards the latter part of March, around when the rain started, a number of very short detection spikes showed up in the 24 hour charts.

Below are examples of a couple of the larger spike detections.

It is normal to occasionally get background spikes, three times background or less. These spike detections were less than three times background, so are probably not anything to be concerned about.

Vital1.  If you suspect the increases and spikes are composed of man made radiation, then the background level should be set to null and the increases multiplied by six hundred if one wishes to convey a truer picture of the biological impact from the increase in industrial- military radiation.   Something to consider.  What is the purpose of posting the chart?

you saw my earlier re-calibration.   The days after the fifth showed an increase, but quite small in counts per minute.  I took only the increase, not the entire radiation quantity and multiplied by the ECRR suggestion for biological effects from man made radiation sources.  I didnt see your comment on this dramatic re-calibration.  Your charts are a nice effort, a good steady log of CPMs but make it appear as if nothing is happening, in my humble opinion.

In a fallout event, how will you evaluate and convey the importance of it?

Code,

I agree with pretty well all you have been saying about the failure of the nuclear industry dose model. It is seriously flawed at assessing the real health risks!

The charts are the best I can do at present, with the equipment available, to establish what the local background radiation level is, at this location. It provides a reference to establish if the background level is increasing, or a major event is occurring.

Momentary, very short spikes could be a cosmic ray event, or something in the air. Without very expensive real time air filter sampling equipment, I have no way of knowing what the source is. There has always been, and will be, short duration spikes showing up in the 24 hour 60 second sampling charts.

My 24 hour charts are using a 60 second sample interval, which is a very short sample period. Most Geiger Counter monitoring charts you see on the Internet are set to sample at 10 minute intervals or longer. With a 10 minute or longer sampling setting, most of the very short duration, small sharp spikes would not show up.
Vital1  Thanks for that reply. 

" It provides a reference to establish if the background level is increasing, or a major event is occurring. "

How much, if any, has the average background CPM gone up since 2011? Have you set some reference levels that will indicate to you that just the background level is increasing, or if a major event is occurring?

we know that a small increase can be a major event.   The recalibration I posted above illustrates that.  Of course it is from your data...so Im wondering if you considered that increase a concern, or noteworthy...

Thanks...just curious
How much, if any, has the average background CPM gone up since 2011?

The local  reference monitoring station's GammaScout Geiger counter died on the 12th September 2018, RIP. The last full day average it recorded was on the 11th September 2018.  Since then I have been using a SBT-10 pancake, using Theremino Geiger counter software and logging in CPM.  

In CPM, local background here at my location in the Southern Hemisphere, has increased by around 15%  + or - 5%  since 2011. As different monitoring equipment is now being used, the long term data does not have the same statistical accuracy.

What I have learnt during this process is that the nuclear industry radiation exposure safety levels, and the equipment used to measure those levels are extremely crude. In my opinion this is by design. If the general public were truly aware  of how very dangerous nuclear radiation and contamination are, all nuclear would be shut down!

"Of course it is from your data...so Im wondering if you considered that increase a concern, or noteworthy..."

In my opinion any increase in background is to be avoided.
