Radiation dose during a flight

During a flight your are exposed to higher levels of cosmic radiation then you you would be on the ground. This leads to the fact that pilots receive more nuclear radiation then poeple working in a nuclear power plant.

If you would like to know how much radiation you received on your last flight you can calculate this here:

Berechnung der Strahlungsdosis w�hrend eines Fluges

Wer in Flugzeugen sitzt ist bekanntlich erh�hter radioaktiver Strahlung aus dem Weltraum ausgesetzt. Piloten erleiden eine h�here Strahlenbelastung als Angestellte eines Kernkraftwerkes.

Wenn Sie wissen wollen wieviel Strahlung Sie auf Ihrem letzten Flug aufgenommen haben oder aufnehmen werden k�nnen Sie dies hier berechen:

Cosmic microwave Background may contain more information about the Dark Age then expected

Scientists found out that in the Dark Age, when the universe was impermable to light, the hydrogen must still have absorbed its resonant waveleght and therefore it should be possible to find out how cosmic matter was distributed in the early universe. Read more:
