She is not a household name in Denmark. But we do have a big mural of her, here in Copenhagen [1].

		I had to look twice, and then check Wikipedia, when I saw "1888-1993" there. * 13. Mai 1888 in Kopenhagen † 21. Februar 1993 in Kopenhagen That's 104 years, 9 months, and 8 days!

Our protection from cosmic radiation is mostly due to Earth's thick atmosphere, not its magnetic field.

Primary defense against cosmic radiation: magnetic field

Secondary defense: atmosphere

The magnetic field deflects particles from the Solar Wind, whereas the atmosphere blocks a lot of the radiation as I understand it.
