In Sweden the largest dose contribution is due to external radiation. The deposition has been mapped by aerial measurements and in situ high-resolution gamma measurements at ground level over the whole country.
Is there still radiation in Sweden?
The average dose rate to the Swedish population has been estimated to less than 0.1 mSv per year, but certain risk groups such as reindeer herders could have received an annual dose of 1–2 mSv per year following the accident (Moberg and Reizenstein 1993).
Was Sweden affected by Chernobyl?
It is now more than two decades since the world's worst nuclear power accident, when a reactor exploded on April 26th 1986 at Chernobyl in the then-Soviet Ukraine. While large tracts of Ukraine, Russia and Belarus were severely contaminated, many parts of Sweden also felt the effects.

How radioactive is Sweden?
The average radiation dose to which the non-smoking part of the Swedish population is exposed is estimated by the SSI to be 2.4 mSv/year (Figure S1).
Which country first detected radiation from Chernobyl?
Forsmark: how Sweden alerted the world about the danger of Chernobyl disaster | News | European Parliament.
How far did the Chernobyl radiation reach?
How large an area was affected by the radioactive fallout? Some 150,000 square kilometres in Belarus, Russia and Ukraine are contaminated and stretch northward of the plant site as far as 500 kilometres.
How the world found out about Chernobyl?
After the explosion, the first westerners to know were Swedish Nuclear plant workers whose sensor's read high levels of radiation. Sweden sent out the first alert that something was happening. It wasn't until the world pointed their satellites towards what is now northern Ukraine, that we realized what had happened.
Is Nagasaki still radioactive?
Is there still radiation in Hiroshima and Nagasaki? The radiation in Hiroshima and Nagasaki today is on a par with the extremely low levels of background radiation (natural radioactivity) present anywhere on Earth. It has no effect on human bodies.
What food has the most radiation?
Brazil nuts are the most radioactive everyday food. However, large quantities of Brazil nuts, lima beans, and bananas all can set off radiation detectors when they pass through shipping. The radiation dose from eating one banana is calculated at 10−7 Sievert or 0.1 microSieverts.
