Interesting experiement conducted by an assistant prof of Tokyo Uni. How much gamma ray can be shielded with 2mm lead sheet casing?
- The air radiation measurement was 2.66 mcSv/h.
- Inside the box measured at 18.27 mcSv/h (the value fluctuated depending on where the probe was placed).
- The test was repeated using two personal dosimeters, one placed inside the box and the other on the outside. The measurements were 3 mcSv/h and 17 mcSv/h respectively.

The jet stream has been making its presence felt in VA, from this jet stream shot if jumps back into VA as it leaves the US. If this is not the cause, what else is causing this location to have such high detections?

Vital-1 asked for any feedback on his/SCCC's revised guides to measuring radiation. Both of them looked good and responsible to me, but I can't be very upbeat –sorry.
* Both guides emphasize the importance of testing food –and properly so.
* Both tell us that we really need a scintillator and spectrometer setup to have any confidence in the results –true. So maybe one person in 100,000 will have the resources (personal, financial), the technical aptitude, the discipline, and the inclination to do this work? So how many will then have the courage, the certification, the liability insurance –to stand up and declare an end to (say) the local fishing industry, or to name a major brand and say something is dangerous to eat?
Clearly: this work has to be done by government –and with the presumed "sovereign immunity" of a government agency. The only way that can happen is to either vote something like the Green Party into power, or to at least take so many votes away from a mainstream party that they're forced into doing the public's interest.
* As to using a Geiger counter, by simply waiting for a period of fairly steady background radiation and doing long counts, I easily read the radiation of a single banana slice, using a Medcom "Inspector" (see: http://webpages.charter.net/123goto/map.htm#1206 –for June 15th).

The problem isn't so much sensitivity, but in discerning the difference between natural and artificial radiation. If I measured significant residual alpha or gamma in a food item (besides the usual potassium beta) or lingering radiation in one of my air filters (after the radon/daughters have died down), I'd need someone with a spectrometer to check it out for me.

1 in 100,000? Probably.
You can get a nice little gamma spectrometer for $2800 bucks for Polimaster: http://www.polimaster.us/products/spectroscopic_personal_radiation_detectors/pm1703mo-1a/
It's bluetooth or USB and has auto ID. I just bought one and hope to have it to test in a few days. I'll post videos on my site about it.
Bejewelled research sell's a multichannel analyzer for about 300 bucks and you can get a detector (NaI(Tl)) for about $500-1000.
Now, for real fun under 10k, get a UCS30 from spectrum techniques =) That's my main workhorse.

Firstly thanks for the feedback. If you set up a Geiger counter and do long counts to test food for contamination, it is better than nothing. This type of Geiger Counter test still won't detect the small amounts of radioactive isotopes that can cause health problems. A Geiger counter is just not sensitive enough. At best you may find the worst contaminated food items.
If you set up a the DIY food testing lab, or purchased a commercial unit, it would be your personal choice to you make your findings public, or just keep them private. It could give your family a lot more protection. The food contamination risk in some areas may not warrant the expense of purchasing a radiation food tester. The food contamination risk level to warrant such a purchase is something people have to work out for themselves. The DIY kit or a commercial food tester may only be an option as a group purchase for a lot of people.
Both guides were designed to give people basic information on using this type of equipment. As is stated in both guides, they are only meant to provide basic information, and it is important not to rely on them, and to do further research. I notice new people coming to this forum all the time that needed some basic info. Having guides means we don't need to constantly repeat answers to the basic questions for new arrivals. It gets them up to speed quickly.

"Clearly: this work has to be done by government"
In a perfect world this may be the case. We find ourselves in a world where we can't rely on governments. By the time you wait for your government to set up and do what is right, it maybe to late. So we have to personally do what needs to be done for the safety of our family, and friends.
For those who read this and don't know what guides we are taking about, here are links to download and read them.

Sickputer,
Thanks for the great research on this thread http://enenews.com/helicopters-measure-radiation-levels-san-francisco-bay-area-next-week
Today is the day that the "Domestic Nuclear Detection Office and the National Nuclear Security Administration" helicopter came to our part of the Bay. There is no way that it was 300 ft up (as in the Homeland Security press release), it didn't even seem 100 ft up, but going close to rooftops, driving people crazy:
http://www.berkeleyside.com/2012/08/29/low-flying-helicopters-over-berkeley-are-measuring-radiation-levels/
While our background has been about 37 CPM (front, west side of house) and 32 (backyard, east side) for much of the summer since the jet stream has been so far north (10 minute tests), today it is 43.4 (west) and 39.7 (east), which is the highest we have recorded with this Radiation Alert Inspector.
It looks like the jet stream made its way to our neighborhood today, plus off and on this past week.

The timing is suspicious to say the least. I'm in the East Bay and typically measure about high 20's to low 30's. The last few days/week I've been seeing high 40's and even a bit over 50 a few times. First time I've seen a spike like that since I bought my geiger six months ago.

At present, I see most people making use of the Geiger Counter Use Guide.
Tip: A Geiger counter with a sensitive pancake probe is more likely to detect radioactive contamination in food than any ordinary Geiger Counter.
In the long term though,
1.The Fukushima nuclear disaster is continuing, and it doesn't look like stopping any time soon.
2.Bio-accumulation has just started, and more food contamination detections will be made over time.
3. As this happens more people and communities will be inclined to make the effort to set up a cost effective food testing system, to protect their families and community.
The DIY food testing lab guide, hopefully, will provide this information to do this quickly and effectively when they need it. Equally, they may decide after reading it to purchase a commercial unit. The DIY unit puts this type of equipment in reach of those with limited resources.
You need a large number of people to jump up and down and demanded their governments test food supplies properly, and truthfully. If this happened then this would also be a good solution.

london radiation reading for 1 september 2012
for the last 2 days the wind has been very still because of a pressure spot and a circulating current is bringing the spewings of La Hague in france straight to us..
eurdep monitors are shoming up to a 0.13 mcSv/h average.
but dont show the range on the graph..
the range is from 0.07 to 0.24 mcSv/h
this means small clouds of intact contamination are slowly meandering around..
earlier i went around the london orbital road (M25) , on the outskirts of london. the reading there was more like 0.08 mcSv/h but the average was more like 0.13 mcSv/h in london central..
the pollution is lingering again
the air quality is worse today but some activity can be seen in west london yesterday (31 august 2012)here
http://www.londonair.org.uk/london/asp/publicbulletin.asp
heres the low level wind chart with the wind circulating from la hague out to the atlantic then back in towards london..
point to note that at the start of august we had the worst pollution episode in 6 years after the march pollution incident etc..
can we break the last olympic pollution record?? is boris johnson spraying around the monitors again?
been busy researching but will report incidents like this.. the rads have been average 0.12 mcSv/h for weeks with little activity

August Report,
The August local background radiation level average was 9% above the 4 year recorded average of 0.10 uSv/hr. Even though this is better than the 43% above average for January 2012, it means our local background has not gone back to normal levels.
See the 2012 monthly average chart.

Here is the 4 year average chart.
http://sccc.org.au/wp-content/uploads/2012/04/Caloundra-local-average-background-radiation-levels-2007-to-2011.jpg
We have had days where the day average increased significantly, but there are no real significant peaks detected, or showing in the 24 hour chart. These increases on these days have happened when solar activity was very quiet, it was dry, no rain, and the wind was coming from the North or North East, from the tropics off the Pacific ocean. This suggests the increased radiation must be well mixed in the air.
Without long term data collection, we would not have noticed this trend.
For those of you who would like to experiment with long term charting,this page now contains templates to help get you started.

Prof. Koide says, by law, materials measuring over 10,000 Bq/kg should be kept under control as dangerous radioactive material.
Later on in the video, Prof Koide measures black stuff from Minamisoma with geiger counter and measures about 10 mcSv/h but its contamination level is beyond the range of spectrometer can handle!!
They say that the black stuff is not cleared from the area because they go by the air measurement (at 50cm above ground) and not by Bq/kg or meter.

Indeed these are the measurements of the 'black substance' found at the locations above. Minamisoma-city measures ** 50 TIMES ** more than the contamination level in Chernobyl compulsory evacuation zone and Tokyo qualifies as inhabitable place too. So, it is really bad. Prof Koide says, it's a level that needs to be cleaned immediately because the black substance is like the dust, if people walk over it, when cyclists run over it, when the wind blows it just keep on shifting as you can imagine. But I think decontamination seems meaningless while Fuku continues to release the radiation so evacuation IS the primary action they need to take.

garrrh! Minamisoma-city spent 40 billion yen to decontaminate the forest but the effort only ended up with increased level of radiation in the air. It is believed that the trimmed grass no longer acted as a shield which caused the rise in radiation level.

Can I ask something about bequerels?
On a site is says the figure as 200 Bqs/gm limit for a waste site ? (I'm assuming yearly)
Normally is per litre or kilogram etc?
I read it could mean Geomertic Mean, and that for example 900 Bq/kg = 0.9 Bq/gm?

Thought I would report my latest test results from a car windscreen sample during light rain from the south west in Melbourne, Australia. Background- 0.12-0.15 uSv hr (pretty normal). Rain sample 0.24 uSv hr. I thought this was pretty good for a rain sample considering the reading is normally back at background levels within 3-4 hours. The sample is now 2 hours old and it still has a reading of 0.24 uSv? This would be the first time I have had a steady elevated reading from such a sample. Although its not a high reading as such, it could possibly mean a radioactive particle is in the sample? Almost a 100% increase from the background and holding steady cannot be a good thing!

Great work Glow! Those MEXT flunkies lie so much that I'd trust a citizen's device over their figures anyday.
(If they couldn't buy gasoline for emergency workers before the Units blew up…what kind of equipment do we think they rolled out nationwide to assess the fallout dangers?)

Depleted uranium has an even higher concentration of the 238U isotope, and even low-enriched uranium, while having a higher proportion of the uranium-235 isotope, is still mostly 238U. Reprocessed uranium is also mainly 238

This Question was posted on another forum,
"Can we detect radioactivity in California naval oranges with our
Inspector Alert knowing that Tokyo Security detected Cesium?”
My answer.
If your Geiger Counter picks up radioactive food or drink, it is definitely
unsafe to eat or drink. Geiger Counters are not sensitive enough to detect the very small amounts of radioactive contamination in food or liquids that can cause health issues.
Two parallel Geiger counter SBM20 tubes which are more sensitive than the
average Geiger Counter can measure down to 2000 Bq/kg activity. This is a factor of 100 too insensitive for detecting radiation in food that could cause health issues.
A scintillator can detect radiation contaminated in food. Also the scintillator needs to be in a lead shielded environment with the food sample during testing. The lead shielding is to help screen out background radiation noise.
Your Inspector Alert Geiger Counter is more sensitive than the average Geiger Counter, but still would not be sensitive enough to detect Cesium in these small amounts detected by security Tokyo.
Tokyo Security:
April 9, 2012
0.47 Bq/kg Cesium 134
0.49 Bq/kg Cesium 137

Turns out it was “Dehydrated California naval oranges” that were tested.
They used a ten hour long count system using a Inspector Geiger Counter. The test result was that the dehydrated oranges tested 20% over background.
Answer:
If you are getting 20% over background with a Geiger Counter, it would suggest that what you are testing is much more contaminated than the Tokyo test results show.
Qualification:
The dehydration could cause a higher than background detection in these oranges. This is because this process has concentrated the potassium K40 content.
All oranges have a high Potassium Chloride content. Part of all Potassium is
radioactive Potassium (K40) which is in all living things.
So there is the possibility that your Inspector Geiger Counter is showing a
higher than background radiation detection, because of the dehydration process has concentrated the K40. The only way to know what is causing this higher detection for sure, is to test it with better equipment.
We have been through this process here, with foods like English Brewers Yeast,Cocoa Powder, and some other dried powdered foods, that have high K40 content. People here using sensitive Geiger counters, or Inspector EXP Geiger Counters, to test these foods where getting much higher that normal background detections.
Report Comment
On testing these suspect items with better equipment we concluded that these
food items had above average Potassium Chloride content.
Concentrated foods with high K40 content can cause false positive detections
with sensitive Geiger Counters like the Inspectors. The only way to know if this is a false positive detection, is to test the sample with much better equipment.
For those of you who can't afford this expensive equipment, you might find this page helpful. "The Food Lab" page has a list of the latest international food detections for radioactive contamination.

Fact 1. Californian Oranges have been detected contaminated with small amounts of Cesium using very sophisticated equipment.
Fact 2. This type of testing is at best a spot checking so some oranges are possibly going to be more or less contaminated, and others not.
Is safe to eat them? It is a very small detection.
Knowing this I wouldn’t eat them, but others would. If I can purchase an Orange from somewhere else that is not contaminated, why take the risk.

Hi Arclight,
No worries about the late reply, I've been a bit unwell last few days so I'm sort of catching up now! Nothing radiation related though
That good old Pb 210!! I thought it would of gone by now? It's Beta decay right?
According to ~ http://esp.cr.usgs.gov/info/lacs/lead.htm
As the para olympics are over now I'm guessing the nuclear bashing is back on? I hope they were all okay and didn't get much of the Pb 210 and whatever other nasties that might of been floating around..
Look forward to the new articles
Can you tell what readings you are getting for the Pb 210?
You serious about 30 billion loses for Edf? That'll set them back for a while!

Here is the Spectrum of radioactive Potassium (K40) Potassium Chloride. This is a test of 430 grams of almost pure Potassium Chloride. Potassium chloride is a natural salt like table salt. Most table salt is Sodium Chloride. A product like Lowsalt has both Potassium Chloride and Sodium Chloride in it. A very small percentage of Potassium in Potassium Chloride is (K40).
These salts are naturally occurring substances in living things on this planet. Different foods have different concentrations of these two salts in them. Without either of them we would die.

Flying from Denver westward last night, the cpm got up to 1047 cpm (average over 30 minutes). Didn't see the reported jet stream dipping down to our track. Typical for the trip was 815 to 894 cpm.
So I wonder what a range of readings were prior to Fukushima?

Did you wear a mask?
They only cost 2.99 at most airport kiosks.
Report Comment
Please explain how a mask protects. It seems at higher altitudes in jet travel, the particles are bombarding from all directions.
I just spoke to one woman who worked with radioactive phosphorous many years ago and had a dosimeter. She said whenever anyone would go on a jet with a dosimeter it would turn it black.
The high readings I reported above were at and after sunset, so really little to no solar radiation.

Does any mask prevent inhalation of xenon gas?
Here is a report of cpm from two different sized geiger counters at 36000 ft done in July 2012: https://ascendingstarseed.wordpress.com/2012/07/14/radiation-at-36000-feet-geiger-counter-on-an-airplane/

The jetstream is the lowest into the states in months, but not too far into Colorado:

BTW… The designation on the jetstream maps 300 mb stands for a measurement of atmospheric pressure (millibar). At sea level the measurement is a little over 1,000 mb (or 1 bar).
300 millibar height is about the height of Mt. Everest or around 9 kilometers. The winds can exceed 100 miles per hour, possibly 200 at times.
" The major jet streams on Earth are westerly winds (flowing west to east). Their paths typically have a meandering shape; jet streams may start, stop, split into two or more parts, combine into one stream, or flow in various directions including the opposite direction of most of the jet. The strongest jet streams are the polar jets, at around 7–12 km (23,000–39,000 ft) above sea level, and the higher and somewhat weaker subtropical jets at around 10–16 km (33,000–52,000 ft). The Northern Hemisphere and the Southern Hemisphere each have both a polar jet and a subtropical jet. The northern hemisphere polar jet flows over the middle to northern latitudes of North America, Europe, and Asia and their intervening oceans, while the southern hemisphere polar jet mostly circles Antarctica all year round."

Anne: Don't you just love the oxymoron statement listed for all the blank Radnet (Sadnet) cities?
"This RadNet monitor is either updating data or experiencing technical difficulties. We are aware of the error, and will post the most accurate data and up-to-date information as soon as possible."
SP: So they are aware of the error, but don't know if it is a data or technical problem?
I think it's a political problem. You can just figure that out by seeing which cities are offline forever. The great cities of the nation and no gamma results.
As I said earlier…these clearcut examples of federal agency malfeasance could be hot smoking guns in an election debate…but when they are never mentioned you can be sure both major parties are bought and paid for. No need to mention who holds the choke collar on these bureaucrats.

What I hate the most is that both Dem and Rep platforms are for more nuclear energy and fracking. Sad that they think they can get away with that stance, and even more sad that voters will vote for those platforms.

The nuclear industry is holding everyone's vote hostage, including the Dems and Reps. The nuclear political sphere of influence in defense, security, and utilities groups is wide and deep. Both Dem and Rep campaigns probably get money from the industry and their lobbies are well funded. Alas, no amount of their influence attempts to curtail the accumulative contamination of nuclear waste. Humans and animals high on the food chain will, sooner than later, experience meltdowns of all supporting biological systems, except for the tardigrades and some jellyfish-
Why there is no international demand to step in, to stop 3(+) reactors from burning off mature, spent fuel into the air for the next ten years, is mind blowing! We continue the old paradigms for money making technologies, without real concern for the growing risk of accumulative damage to future generations. Is our DNA imprinted with helplessness from previous catastrophes, or what? Janet says stay calm no matter what. Good luck to everyone with that. Are our finance systems totally defunct and useless to clean our nuclear house? There might not be a need for future Dem and Rep platforms, the way we're going-

One other thing, I wanted to thank everyone on this board profusely for your commitment to information research and monitoring radiation! Coming here is refreshing and exhilarating if not, occasionally, terrifying-
The reality of radiation accumulation from Fukushima (and other sources) can be explored and weighed upon here, while outside talking to the general public, not so much. Like more cowbell, info about the continual exposure to and accumulation of man-made radiation, needs to be spread wide and far!
