Is EU a radioactive?
Eu (half-life 4.7612 years) has a fission yield of 330 parts per million (ppm) for uranium-235 and thermal neutrons; most of it is transmuted to non-radioactive and nonabsorptive gadolinium-156 by the end of fuel burnup.
Is radon present in Europe?
In normal circumstances, radon is the most important contributor to the radiation exposure of the human population. Although the gas occurs naturally and is found in low levels throughout the EU, higher levels of radon put people at greater risk of developing lung cancer.
What is the highest radioactivity?
The Most Radioactive Places on Earth
- Uranium: 4.5 billion years.
- Plutonium 239: 24,300 years.
- Plutonium 238: 87.7 years.
- Cesium 137: 30.2 years.
- Strontium-90: 28-years.
What type of metal is EU?
europium
europium (Eu), chemical element, a rare-earth metal of the lanthanide series of the periodic table.

Where is the most radioactive place in the UK?
The middle of the vast moorland that is Dartmoor National Park is the worst place in the country for radon, as the ground rock is mostly granite, which contains small amounts of uranium that decays and produces the gas. Residents in Dartmoor can be exposed to as much as seven millisieverts of radiation per year.
Does Germany have radon?
The average radon concentration in Germany is 49 Bq/m 3, and per year 37,700 persons die of lung cancer. Of these, 1896 cases (PAR 5%) can be attributed to radon. Nevertheless, radon in homes is the most relevant lung cancer risk in the German population after tobacco.
Which country has the most radon?
According to the Norwegian Radiation Protection Authority, “Norway is among the countries in the world where indoor radon reaches its highest concentrations”. About 10% of all buildings in Norway have a concentration higher than the recommended 100 Bq/m3.
Are smokers lungs radioactive?
Cigarettes made from this tobacco still contain these radioactive elements. The radioactive particles settle in smokers’ lungs, where they build up as long as the person smokes. Over time, the radiation can damage the lungs and can contribute to lung cancer.
Is EU a main group metal?
The main-group metals usually form charges that are the same as their group number: that is, the Group 1A metals such as sodium and potassium form +1 charges, the Group 2A metals such as magnesium and calcium form 2+ charges, and the Group 3A metals such as aluminum form 3+ charges….Metals, Metalloids, and Nonmetals.

What was the EU Directive on radiation protection in 1990?
(OJ L-180 of 09/07/97 page 22) Council Directive of 4 December 1990 on the operational protection of outside workers exposed to the risk of ionizing radiation during their activities in controlled areas. (OJ L-349 of 13/12/90 page 21)
Where can you find radioactivity in the world?
Radioactivity is an integral part of our environment. All living beings have been exposed to a constant flux of natural radiation on the surface of our friendly planet: to no negative effect. We find the majority of naturally-occurring radioactive elements in rocks.
How many millisieverts of radioactivity per year in France?
In France, the exposure dose is 2.4 millisieverts per person per year, as opposed to 1mSv from medical examinations. This is, of course, an average, and location and lifestyle play equal roles in determining the level of exposure. Where one travels, where one lives and even whether or not one uses air conditioning are all important factors.
What is the European Atlas of natural radiation?
The European Atlas of Natural Radiation provides reference values for natural sources of radiation across the EU. The European Atlas of Natural Radiation provides harmonised data on levels of natural radiation across the EU and aims to raise awareness among Europeans of living with natural radioactivity.
