I forgot to mention something about using normal steel for shielding:

It should have the lowest possible carbon content. (That's usually what you receive if you buy cheap steel sheet, plate or pipe, so you might not need to worry about it.)

I found this site with information on EU alloy numbering: http://www.steelnumber.com/en/number_en10027_eu.php

In the US, ASTM 1008 is an OK alloy.
