Talk:Radiation shielding

^(M Lamontagne)

I changed the meaning of the magnetic shielding section as it excluded magnetic shielding without sufficient analysis. In particular it didn't refer to minimagnetospheres, and their existence ;on the moon. The mechanism of a minimagnetosphere may be electric rather than simply magnetic, with particles being ionised by the shield and then deflected by the electrical field potential. Cosmic :rays might be deflected by very large shields with low densities.

Some material (the Beer Lamberth law, linear attenuation coefficients, and half value layers) appears to apply only to electromagnetic radiation, so I added a subheading to specify this and allow a comparison of these considerations with particle considerations.  If I am wrong about this please correct me.
