This is a super condensed table on how to interpret Geiger Readings. Use it to supplement your own research and getting a "block of knowledge".
If you take this radiation stuff at all seriously, then get a Geiger. All the rest is guesswork.
Radiation Alert Inspector, $530 to $600 Amazon
Sometimes, Radiation reporting websites will express radiation readings (based on assumption of Cesium) as microREM/Hour. AS an example, if they are stating 11 microREM/H you divide by 100 to get .11mSv.
This table is based on the Radiation Alert Inspector which is a fine pancake tube type device. The Clicks that any device produces are based on its own "efficiency" in detecting various types of the alpha, beta, or gamma. These can then be converted to a mSv making a huge assumption, i.e. the isotope. Usually Cs is chosen for this guess. But you don't really know the mSv until you know the isotopes involved.
If you have a cheaper, small tube type Geiger, you are going to pick up less Clicks.
And Here are LIVE radiation reports from independent reporting stations.
I am sending my Radiation Alert Inspector to Japan to a family that needs real data---soooo You won't see an Oahu based reporting station until I get my next Geiger delivered.
Japan –only 2 to 5 reporting sites

Veterans Today is a great site, but sometimes they "juice it" up. http://www.veteranstoday.com/2015/04/03/your-radiation-this-week/
They report weekly max radiation readings, using sensitive EPA gamma monitors. A reader asks.....

Hi
Stock. Are you able to explain the discrepancy between Bob Nichol's
Your Radiation This Week and http://radiationnetwork.com/ above?
ReplyDelete
Simple: He is using the EPA reports that include very sensitive gamma radiation reading (in 8 different energy ranges incidentally), compared to radnet which is comprised of VARIOUS Geiger counters, that are catching some Alpha, but mostly beta and gamma and they are not as sensitive.
So a CPM means little unless you the type of Geiger that took it.
Seeing 50CPM on a nice Radiation Inspector Alert would not be a "take action level" but if you have an el cheapo $160 Geiger, and you are seeing 50CPM it may very well be a "figure out what the hell is going on" moment.

Saw your post at HP. That's wonderful news your sending yours to a family in Japan Steveo. Thanks to you, they'll be able to measure the radiation around them. HUGS to you!
ReplyDeleteYeah It was kind of an epiphany on Saturday.
DeleteDo you know what the readings are in the Hawaiian Islands?
ReplyDeleteThanks for the important info!
I too am trying to make sense of the data. We used to measure radiation in RADS, now it's called millisieverts, microsieverts, bequerals and terabequerels (X1000 to the 10thpower). First you measure the "background" radiation that "normally" exists (ie, from microwave ovens, cel phones, wi-fi etc.)then measure your item (the vegetable at the grocery store or the paper towel from which you swiped radioactive rain off your car)-- subtract the background reading to get your result. The "standard", which a human body can withstand, was set at 0.05 millisieverts. Now they've raised the standard so we can "safely" absorb more radiation, (by the way, the black yetch on the streets in Tokyo is measuring in bequerals) My guess is that the industry is purposely confusing us with measurements since no amount of radiation is really "safe". Yes, I too would like to make sense of all this. I'm learning that many of the geiger counters don't even measure cesium, strontium and plutonium, which is what is coming our way from Japan.
ReplyDeleteThanks for stopping in, and for making efforts to understand this stuff. All your comments seem on the right track.
DeleteFood is very hard to measure, the water stops most radiation, but if you do get a high reading on food...very bad sign.
Clicks per minute is a good standard, it eliminates all the assumptions, such as to convert CPM into mSv one must make an assumption of what type of element is causing the click (Cesium is a common assumption that many Geiger manufacturers build into their calibration/calculation to produce mSv.)
Normal radiation sources are deep space, the sun, rocks & minerals around you, etc. NOT microwave ovens, cell phones, wi-fi. These emit "radiation" but they do so much lower in the electromagnetic spectrum and do not emit alpha, beta, or gamma. Repeat: Microwave ovens, cell phones, wi-fi, etc. do NOT emit *ionizing* radiation and are not of concern at ALL in this discussion.
DeleteNone of those "radios" (or EMI sources) are truly digital in the sense that they only broadcast on one specific frequency, except perhaps some SMARTmeters.
DeleteWhat you might be measuring could be harmonics of the main "transmission".
If you don't believe me, obtain a small battery-powered AM Radio. Tune in to a strong frequency about mid-dial near the center of the room. Then move it close to any WiFi antennae, operating Microwave oven (with a cup of water inside for instance), LCD-TV, etc., etc., etc.
In short, you are wrong, but not for any of the reasons you cited.
Nice spelling though.
Also, if anyone can generate any ions, or charged particles, from such emissions, would that not technically be "ionizing" radiation?

DeletePLEASE contact me on Facebook (Marushka France) you are spreading MISinformation
ReplyDeleteI have considered this chart propaganda, so I'm glad you've identified yourself as the author>>>
First of all the first line is propaganda, because even post-Cherobyl.... a level of 1 mSv/ year was consider --internationally -- the standard and an achievable standard for the public's safety.... It doesnt get much lower is misinformation when you don't say.....
GIVEN SEVEN DECADES OF EXPOSURE
-- global and horrifically high exposure from the era of atomic bomb tests is directly responsible for the global rise in cancers and chronic diseases
-- Chernobyl increased exposure globally, cerrtain areas are hot spots of activity and research in those areas is proving -- as if it needed to be proven again -- that Nuclear is lethal and should cease entirely.
-- Fukushima fallout is 100 to 1,000 times worse than Chernobyl
-- RadNet CPM readings are at least 2 to 3 times higher than before Fukushima...
ONE mSv/year has been the International Standard,,,,, brought down from FIVE because research repeatedly showed.... FIVE is profoundly Deadlier...
Only one test - western medicine -- is repeatedly done for people with cardiovascular disease. It's so high in exposure that if included and averaged for all USA citizens,,, amounts to 3mSv/year!!!!!

Measure Radiation in Food
ReplyDelete"Geiger Counters are pretty useless if you want to deal with the real thing: Radionuclides in food. Air radiation is not representative for radionuclides in food and soil.
These are devices people should buy:

27 Chernobyl years and people still don't know this and do not measure their food."
Suggest people form communities, familial, civic, church, to get the right equipment and testing soils, food and water for alpha beta AND gamma.
Internal exposure thru food and water is the most hazardous.
To protect yourself, simply, Dr. Rosalie Bertell suggested drinking distilled water between meals and supplement with spirulina... these draw radioisotopes to it for elimination.
With Meals, supplement with calcium/magnesium.... 850 mg/350mg, respectively, (half that for a 10 year old) is the advice of Chris Busby. Add antioxidants.

@Marushka France - Bonjour! I like your constructive criticism.
ReplyDeleteWould thinly slicing & dehydrating foodstuffs ease detection?
Am looking for simple Do It Yourself projects utilizing common semiconductors such as 2N2222A (etc) powered by +5VDC (USB) to output via headphone adapter for desktops & laptops? I understand the utility would be limited, like the bandwidth, to Gamma, and some beta. In my mind it is better than nothing.
Am looking for something very simple that does not require any programmable chip, yet can use simple ic's such as comparators and discrete components. It need not be very accurate. Am thinking +/- 20% would be ok for a "kids toy" for people whom have very low income.
That would be combined with freely available pulse recording software, such as Marek Dolleiser's "PRA" (University of Sydney).

What brand and model Geiger did you get?
DeleteHi Stock. Are you able to explain the discrepancy between Bob Nichol's Your Radiation This Week and http://radiationnetwork.com/ above?
ReplyDeleteSimple: He is using the EPA reports that include very sensitive gamma radiation reading (in 8 different energy ranges incidentally), compared to radnet which is comprised of VARIOUS Geiger counters, that are catching some Alpha, but mostly beta and gamma and they are not as sensitive.
DeleteSo a CPM means little unless you the type of Geiger that took it.
Seeing 50CPM on a nice Radiation Inspector Alert would not be a "take action level" but if you have an el cheapo $160 Geiger, and you are seeing 50CPM it may very well be a "figure out what the hell is going on" moment.
Follow up Q?s, Stock: Considering that Nichols states that the readings he is citing are not the whole story, either, ie: understate the actual, is there any public access source to your knowledge that gives a more complete reading?
ReplyDeleteDo you think that Nichols is in effect 'mixing apples and oranges', as it were, by including a 'normal traditional background' as say five to twenty CPM, which sounds like what lower end geigers might indicate, with EPA extremely sensitive technology? To put it another way, what would that EPA technology posit as 'normal background'? His numbers seem at first glance extremely disturbing. How do they strike you? Thanks, Oldster.
Oldster, watch the youtube by antiproton, it will double your knowledge in 15 minutes and never have to be uncertain again.
DeleteIn regards to "Seeing 50CPM on a nice Radiation Inspector Alert would not be a "take action level" but if you have an el cheapo $160 Geiger, and you are seeing 50CPM it may very well be a "figure out what the hell is going on" moment" - I have a reading of 390CPM taken with a Smart Geiger device on my iphone. Is there any translation to the real world? Thanks!
ReplyDeleteposted question to ENENEWS, see if anyone has experience
DeleteI recently measured 344 cpm a b and g from the sap of a dieing tree. Seems way too high not to be manmade. Background was 34cpm , and the Inspector plus was used.What might be happening here?
ReplyDeleteInteresting. No experience in sap, but did you dry the sap, just curious.
DeleteTry same test but block the alpha window.
Then try using a beta blocker, like some thick heavy material....I prefer lead because I have those sheets on hand for solar work.
Then some sleuthing can occur.
I tested dried crystalline sap on a piece of bark from the same tree. Alpha at 22 cpm beta at 163 cpm gamma at 40 cpm.
DeleteVery nice chart, I would like to translate it to German and post it on my website, with reference to you, is that okay?
