[ RadSafe ] Mars Radiation Won't Harm Astronauts, Curiosity Rover Finds

Mon Nov 19 13:17:33 CST 2012

Dear Radsafe et al.:

     There are books on the Earth's magnetic field and  the Earth's core.
An introductory geophysics book is by Frank Stacey.  Books on Earth  Core, 
Earth Orientation/
Rotation and so on are:  Munk and MacDonald, Lambeck I and Lambeck  II.

     Stacey book also has a chapter on use of  radioisotopes in geophysics 
(dating etc.)

     Take Care...  Joe Preisig

Dan, watch the movie titled "the core", here is the trailer

Although  many aspects of the technology used defy the laws that we 
currently know, but  still interesting
