Radioaktivt avfall - Sediment i öppet hav - Så här vilseleder Strålsäkerhetsmyndigheten

Radioaktivt avfall - Sediment i öppet hav

Många föroreningar som släpps ut i naturen hamnar till slut i sedimenten på havsbottnarna.
Detta gäller även de radionuklider som lätt binds till partiklar och sedimenterar till botten tillsammans med dessa.
Genom att kartlägga koncentrationerna i sediment från öppet hav får vi en översiktlig bild av hur belastningen varierar mellan havsområdena. Eftersom nytt material hela tiden faller ned på botten ovanpå de gamla sedimenten fungerar koncentrationerna i sedimentens olika skikt även som ett arkiv över hur halterna i miljön har varierat över tiden.

Första provtagningen år 2003

2003 genomfördes den första provtagningen i ett nationellt övervakningsprogram för sediment i öppet hav. Programmet omfattar 16 stationer runt Sverige. Avsikten är att ta prover vart femte år på dessa stationer. Strålsäkerhetsmyndigheten låter ta prover inom programmet för analys av radioaktiva ämnen och analyserar för närvarande dessa prover med avseende på innehåll av ¹³⁷Cs. Programmet i sin helhet omfattar även metaller och organiska miljögifter och utförs av Sveriges geologiska undersökning (SGU) på uppdrag av Naturvårdsverket. Data för metaller och miljögifter finns hos SGU.

Sveriges geologiska undersökning

Analyser av ¹³⁷Cs visar att de totala mängderna i sedimenten är högst i Bottenhavet och Ålands hav, 15–50 kBq/m². I egentliga Östersjön och längre söderut är mängderna 0,5–3 kBq/m². Mängden ¹³⁷Cs i sedimenten är alltså korrelerad till nedfallet efter Tjernobylolyckan på regional nivå.

¹³⁷Cs har också analyserats i samband med att SGU har karterat bottnarna nära kusten i Mälaren, Ålands hav och Bottenhavet. I denna kartering har mängder på upp till 110 kBq/m²noterats i såväl Bottenhavet som Mälaren. Som jämförelse kan nämnas att den högsta mängd rapporterad från Östersjön är 125 kBq/m² vid en finsk station i norra Bottenhavet.

Halten (Bq/kg torrvikt) i den översta delen av sedimenten, vilken motsvarar dagens belastning, skiljer sig mindre mellan olika områden än de totala mängderna i de äldre och djupare delarna av sedimentet.

Detta beror på att det sker en utjämning mellan de olika områdena vad avser koncentrationer i vatten, och sediment genom att vatten, och därmed resuspenderat material, rör sig med strömmarna.

Detta innebär också att djupprofilerna för koncentrationerna av ¹³⁷Cs kan se mycket olika ut i olika delar av Östersjön. Ostörda profiler i Ålands hav och Bottenhavet kan uppvisa en profil där sediment som bildades 1986 syns som en tydlig topp. I omkringliggande områden, där halterna inte blev så höga direkt men dit ¹³⁷Cs efterhand börjat sprida sig, till exempel Bottenviken, kan profilen i stället uppvisa stigande halter mot ytan.

Halterna i sedimenten bedöms inte utgöra något hälso- eller miljöproblem. Strålningen till de organismer som lever i eller nära sedimenten bedöms vara långt under vad som kan anses skadligt, och överföringen till människor via exempelvis fisk är låg.

Fukushima fallout on air on 2011

Almost all bottom trawled fish as pollock, salmon and 
herring are typically contamined by radioactive Cesium-137. 


Effects of Bottom Trawling

Bottom trawling can destroy coral reefs and disrupt sediment and bottom-dwelling marine life, creating plumes that can be seen from space.

Unwanted fish or marine life can  make up 40-90% of the bycatch that is cought and subsequently thrown back.

Product Features

Smart Geiger is a sub-miniature sensor of cheap price which can detect radioactivity easily and conveniently by connecting to the earphone jack of a smart phone.
It indicated radiation coming out from a radioactive substance in dose-rate figure (uSv/h) and informs even by sound, using semiconductor sensor.
The measurement error is approx. within 30% because there are many different kinds of smart-phones in the market.
Therefore, you may leave the exact measurement of radiation dose to experts, and you can carry out preliminary simple measurement by inserting Smart Geiger into the smart-phone.

Smart Geiger is manufactured by R&D specialized company, FT Lab with a sense of mission, which has obtained 3 New Technology Certifications during the last 14 years of its R&D career.

A practical measurement example,  (FSG-001):

- a grocery store in the Greater Helsinki area—specifically in Hakunila, Vantaa—an area plagued by serious immigration-related problems, street and school violence, gang _apes, robberies and vehicle arsons.  

In the poorest apartment-block suburbs of Southern Finland—built in the 1970s—people are fighting for survival; living below the EU poverty line, they have resigned themselves to food queues and hopelessness, and have become passive.

Food industry operators, wholesalers, and retailers have knowingly exposed consumers to risks affecting their health and lives.

https://graviolateam.blogspot.com/2025/04/food-aid-workers-around-country-report.html

There is practically no monitoring of radioactive radiation! Fishermen, logistics personnel, merchants, staff, and food safety inspectors do not have Geiger counters.

In this example video, filmed at a K-Market in Vantaa, radiation levels rise to 1,130 times the normal background radiation.

- This fish (herring) is emitting radiation so strongly that one should only approach it while wearing a protective suit.

In the aftermath of the Chernobyl accident (April 26, 1986), the highest dose rate measured in Finland was "only" 5 µSv/h.

- So, the level at this fish display is 23 times higher..

https://www.youtube.com/watch?v=9RLrHx1kC1M

In the measurement video, the radiation dose rate of a
Baltic Sea -trawled herring fillet rises to 113.07 μSv/h.

UPDATE 28th Mar 2017
- (FSG-001) Reference measurements

Comparative measurements performed today on Tues. 28.3.17 in Helsinki University Hospital Radiation Therapy Ward, cancer clinic. 

Since it was not commonly believed the K -Market herring radiation results, obtained during consecutive days from 24th to 26th Mar, highest result 113.07 mSv / h (above). 

Today on 28th Mar 17, we measured values ​​of Radiation Therapy Ward department at Helsinki University Hospital (HUS) cancer clinic, in the lobby and in the basement, that is, 0-floor, wherein the radiation therapy is administered to patients in separate, numbered rooms.

The maximum value of 2.20 mSv / h, in font of the the operating room No. 6. In which operator apparently just "kicked the pedal" when we passed the door.
