According to UNSCEAR 2000 report, Ramsar, in northern Iran, has some inhabited areas with the highest known natural radiation levels in the world.
What areas have high background radiation?
Areas with unusually high background (high background radiation areas, or HBRAs) are found in Yangjiang, China; Kerala, India; Guarapari, Brazil; and Ramsar, Iran. Some areas of Ramsar, a city in northern Iran, have among the highest known background radiation levels in the world.
Why does Finland have high background radiation?
In many places in Finland, actual radiation doses are far higher than that. The ice ages scraped our soil down to bedrock, and bedrock contains considerable quantities of uranium. As it decays, one of the decay products is an odorless, invisible and radioactive gas known as radon.
What is the most naturally radioactive place on earth?
On the coast of the Caspian Sea, the city of Ramsar, Iran has such high natural background radiation levels that scientists have recommended that the 32,000 residents relocate. Its neighbourhood of Talesh Mahalleh, the most naturally radioactive inhabited area in the world, is under long-term study.
What is the biggest source of background radiation in the UK?
radon gas The 2.7 mSv dose that people in the UK are exposed to comes from a number of sources. Many building materials contain low degrees of natural radioactivity and radon gas seeps from the ground into all buildings, so the largest exposure is to naturally occurring radiation in homes and workplaces.
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.
Who is the most radioactive person?
Stevens died of heart disease some 20 years later, having accumulated an effective radiation dose of 64 Sv (6400 rem) over that period, i.e. an average of 3 Sv per year or 350 μSv/h….

|---|---|
| Nationality | American |
| Occupation | House painter |

Why are Brazil nuts radioactive?
They consist of a significant amount of radium that contributes to their radioactivity. Brazil nuts (especially the ones grown in Brazil) grow on trees that have deep roots, which reach into the soil to produce high amounts of natural radium, a source of radiation.
Why is background radiation higher in some places?
Average annual doses of radiation in different countries (in millisieverts per year). Some areas with sizable populations have much higher than average background radiation levels. The highest are found primarily in Brazil, India and China and are due to high concentrations of radioactive minerals in the soil.
Is Hiroshima still recovering?
Hiroshima had been completely destroyed by the A-bomb, but gradually electricity, transportation, and other functions were restored. The people collected any unburned materials they could find and began rebuilding their homes and their lives.
