Geiger Counter Interpretation Simplified

I made this chart.   Several other blogs have copied it nearly verbatim, and I am happy that others want to spread actionable information to protect people (would have been nice to get a proper credit though).   I had the chart translated to Japanese as I was sending a Geiger to Japan to help families address their real risk.   See bottom for the Japanese version.

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

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
Hawaii –
US Mainland


  1. 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!

    1. Yeah It was kind of an epiphany on Saturday.

  2. Do you know what the readings are in the Hawaiian Islands?

    Thanks for the important info!

  3. 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.

    1. Thanks for stopping in, and for making efforts to understand this stuff. All your comments seem on the right track.

      Food 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.)

    2. 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.

    3. None of those "radios" (or EMI sources) are truly digital in the sense that they only broadcast on one specific frequency, except perhaps some SMARTmeters.

      What 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?

      Due return when you have enough knowledge to best a McDonald's worker, eh?

    1. Great stuff, I am posting these up as their own post on my site.

  6. Thank you for your time and hard work. It is greatly appreciated!

    1. You are welcome. Spread the word, protect people, kill nuke

  7. Thank you so much for all this resource. I like your practical approach and simple language.

    1. Decipher the technical BS and put it into straight forward terms. Appreciate the appreciation!

  8. im going to spread the word ,for years I was pro-nuke .Its nastier than raw sewage.
    I thank God for the truth.

    1. Nuke makes raw sewage look like fine art.

  9. PLEASE contact me on Facebook (Marushka France) you are spreading MISinformation
    I 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.....
    -- 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!!!!!

  10. inhalation or exposure to airborne radionuclides (cloud shine)." (pg. 23).

  12. That was just the forward translation. There are bound to be inaccuracies.
    Those might be reduced via reverse translation & rephrasing, "rinsing & repeating".

    Perhaps there's an API for that.

    Intel might unwittingly even have two thirds the seed money for the first million characters of text. :) (no receipt required, apparently)

  13. Quote of ISPC: "Maybe I will build inexpensive Geiger Counters and give them away."

    Do tell. How can i be a Do It Yourself'er for educational purposes & for charity?
    Can i calibrate with a bag of dehydrated bananas? (oh the irony, eh?)

  14. Measure Radiation in Food

    "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.

  15. @Marushka France - Bonjour! I like your constructive criticism.

    Would 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).
    (web site down at the moment - )

    At the moment, it seems leadership here is content to let us eat yellowcake, so-to-speak.

    Quote: "Emergency radiation testing used at Democrat and Republican conventions after Fukushima; Also for Obama Inauguration — Seafood, meat, vegetables, milk, water checked for nuclear waste, while top officials agree to publicly downplay crisis — 80% of milk samples by Orlando, FL had ‘significant’ Cs-137"

    I will close my mouth and open my ears, so learning can begin.
    I appreciate your opinions, Marushka. Merci beaucoup.

    1. Apologies for breaking silence.

      There appear to have been attacks on enenews people from Oak Ridge, if that is correct. Stock might be a little preoccupied at the moment. Many were infected. There might have been a BIOS attack too, yet that is as of yet unconfirmed.

      See: & (etc) That last link seems to link at least part of the "malefactory crew" with the address, and there is a picture there too.

      Had appealed to EFF board member Mr. Schneier's Security site via a comment, though nobody has responded. :(

      Closing mouth, opening ears .... over to you sir.

    2. I was wondering what happened, there. I posted a comment, then decided to post a reply to another enenewser, and got a 404 error message. I could still go to and read ENEnews, but could not post responses.
      I wonder if it's one of the pro-nuke jerks (which may be on in the same) J-anAlex or Metalhead?

  16. Thanks for this!
    I just got my geiger-counter, and my bedroom is in the high-teens; kitchen in the mid-twenties (food? water? who knows?) I was thinking I'd test food while I'm waiting to see when I might need it.
    Always want to be prepared..

    1. What brand and model Geiger did you get?
