Tea bag

  • Sampled on June 8, 2012
  • Cs134= 76 Bq/kg
  • Cs137 = 120 Bq/kg
  • Total Cesium = 196 Bq/kg
  • Not exceeding Codex guideline levels
  • Voluntary surrendered by importer for disposal. Not distributed for sale in local market.

Perhaps Hong Kong maintains similar laws to what Japan had before 3/11:

Previously, Japanese regulations required nuclear waste with 100 or more bq/kg of Cesium to be monitored and disposed of in specialized containers.

Oatmeal was also found to be radioactive in recent testing by Hong Kong authorities:

  • Sampled on August 1, 2012
  • Cs134= N/D Bq/kg
  • Cs137 = 7 Bq/kg
  • Not exceeding Codex guideline levels

    [article extract] "CFS (Hong Kong – Center for Food Safety) did not order a recall of the product because the dietary exposure shows the internal dose of Cs-137 even at high consumption, figured at 90 grams per day, would not be enough to result in adverse health effects."

    Why then, was the product 'voluntarily' pulled? Is a product pulled only-when it's discovered to be contaminated?

    [article extract] "Hong Kong, one of two special administrative regions of the People's Republic of China (the other being Macau), has been conducting daily tests for radioactivity of food from Japan since March 12, 2011."

    Curious as to what's being done to test food and food-ingredients coming into other nations; from that entire region, as well as Japan, itself…

    Really! The nerve of these people stopping nuke plant operations!

    i am glad hongkong are testing, my youngest is going there next week 🙂

    As I have been saying to folks since day 1….do NOT eat ANYTHING from Japan again. It is a done deal if you care about your long term health. It is simply not worth the gamble IMO.

    Radioactive isotopes found in Brazil nuts purchased at the local supermarket. See test chart.

    The chart shows radioactive lead isotopes are present. The second green peak marker in the chart is at 241 keV and other peaks at 295, 351, are the markers for radioactive lead. Then the other largest peak is for Bismuth 214 at 609 etc. The large blue coloured peak is the secondary X-rays, a product of a test chamber not being lined with copper and the smaller blue coloured peak is Potassium K40 found in all living things. These results suggest this contamination is not from Fukushima because of the presents of Bismuth 214.

    Information on Brazil nuts.,

    1. Brazil nut trees produce fruit almost exclusively in pristine forests.

    2. The fruit takes 14 months to mature after pollination of the flowers.

    3. Around 20,000 tons of Brazil nuts are harvested each year, of which Bolivia accounts for about 50%, Brazil 40% and Peru 10% (2000 estimates).

    Now we have a lot of questions.

    Where have these lead Isotopes come from?

    Soil contamination from the forest during harvesting?

    Uranium dust contamination South America?

    Uranium dust after import into Australia?

    Washed them and ran the test again, same result, so this rules the out uranium dust and soil contamination.

    Bi-accumulation from root up take? This appears to be the most likely possibility.

      If I can detect radioactive Lead and Bismuth in Brazil nuts it also suggests there must also be levels of stable lead also present. I have taken Brazil nuts off my diet. If I had detected this in any other food I would do the same.

      In my opinion, ideally if you are consuming something as a food it should not show any peaks in this region. Brazil nuts need further testing by others with this sort of equipment, to verify this. Note, samples harvested from different locations may test differently.


      DIY Food testing lab set up free guide, first draft. The next planed update to this guide will be an isotope Kev identification table.

      If you have any suggestions or additions to improve either guide, please
      post suggestion into this enenews forum.

        One suggestion has been that Brazil nut trees are bio-accumulating the naturally occurring radioactive lead isotopes that can be found in most soils, because of their very deep root systems.

        It is well-documented that Brazil nuts are a naturally-occurring radiation source, along with a few other common foods beside the now-infamous banana. Of course, they might contain other non-natural radiation sources as well these days.

        Lots of online references if you're curious, for example:

        This one is interesting because it points out several other risks associated with Brazil nuts. Who knew?…

        I seem to remember that Tom (anti-protons) has some Brazil nut tests on his website.

          Thanks for those links,

          Quote, from your second link above.

          "It's believed Brazil nuts have 1,000 times more radium than the next most radioactive food. While extensive studies have yet to be conducted, the amount of radiation in a Brazil nut is still small when compared to radiation encountered in everyday life, and it's not believed to pose any serious health risk, regardless of the quantities ingested."


        @vital1: excellent PDF manual. Thanks for this work…

      FYI, Brazil nuts get their radiation from barium

      Like using carbon dating, everything is radioactive in some sense, includes your own body. Trees store up the sun's energy and when you burn wood the energy is released. Same with fossil fuels for the most part. Boulders have higher concentrations and being exposed to sunlight are all ways of getting higher doses of radiation.

      Naturally occurring radiation is secondary rather than primary exposure to man made radiation, that is what is of concern.

    Ugh. I know this is just an early-stage FWP, but I hate having to pass up so many foodstuffs at the Asian markets. Got about half a bag of pre-311 wakame left, some kelp from Korea, bonito flakes that are probably post-311, and I still buy natto b/c I haven't gotten around to making my own yet. Then there's the cherries (from PNW) which just make me sad to pass up.

    I am still of childbearing age, and thankfully have a definite streak of longevity in the genes (most family members last three gens have lived far beyond what their level of health would indicate). Do I protect these genes some more just in case I end up with child, or give up on bringing new people into such a fucked-up world?

      Tough call. And I would blame you on a decision either way. Your decision to make.

      There are pure mud preparations to soak your food in before cooking or eating. Mud (calcium) has a tendency to draw out radioactive minerals, also blocks the body from up taking radioactive minerals.

      Not to much information out there on it but some.

      If you don't want to take a chance on your own offspring, there are homeless kids and babies in the world that you could call your own.

    Sorry about that, "I wouldn't blame you on a decision either way."
