Depleted uranium takes even less space, and is probably cheap. I'm not
sure how it should be cut though

Plus the added bonus of your window frames glowing in the dark :-)


DEPLETED uranium is NOT radioactive.

Citation? How about http://www.grip.org/bdg/pdf/g1861.pdf ?

Depleted uranium typically has around 0.3% to 0.2% 235U by mass,
although the Nuclear Regulatory Commission in the US defines DU as
uranium in which the percentage of 235U is less than 0.711% (NRC, 2000)
