In our increasingly fast trip, we pass immediately to the 1'000 light-years distant giant star Betelgeuse (Alpha Orionis). It is a red giant with fewer than 1'000 times of solar diamteter. After we have learned that the sun has 100 times the diameter of the earth, we must imagine, if our sun would be as big as Betelgeuse, the orbit of the earth would be located in the interior of the star. How hot!
This number is easier than 10 EBq (Eta-Bequerel) represent. This radioactivity is contained in about 100 transport and storage casks with vitrified HLW or spent fuel. It can be compared with an inventory of the half-filled HAA camp in the central interim storage facility in Switzerland. Each year 3E +19 Bq Rn-222 released by withdrawal from the Earth's interior to the atmosphere. This decays to Po-218 and can be absorbed into the body by inhalation of particulate.
In 10 trillion seconds, or in 300 billion years , we have probably about 10 Big Bang's already lived through, if you can survive such a bang.
