    Not really something I could cobble to the G1

    One "hot" lens. Too bad it weighs a ton, it's pretty fast for its focal length.

    Some of the older Canon FD lenses have radioactivity as well - thorium specifically. The 35mm/2.0 for example is known to be radioactive (the ones that go to f/16). Also some of the FL lenses.

    Also some of the Pentax Takumar m42 mount lenses. I had the 35mm f2.0 and it was.

    I have two copies of the Kodak Aero Ektar 178/2.5 lens. One is in its original barrel mount and one has been adapted to M42 mount with a focusing helicoid. The lenses are big and badly radioactive, but I don't think they are a major health threat. I just won't store them in my bedroom . Here's the one in M42 mount on my Pentax K10d (a rather big DSLR):



    Here's a picture taken wide open at F/2.5:

    Yes, they don't pose any health risks, they are bulky. Produce dreamy looking images as well, as yours show.
