Re: Grainy images?
It might help, but the radiation isn't just coming through the lens, I would guess. Adding enough shielding to block all gamma rays might be impossible due to weight constraints. The X-rays blocked by CRT tubes are rather less energetic than these gamma rays, I think (10s of keV vs >100 keV, AFAIK)
Edit: I see I should speed-up my typing ;-)
