Short answer: radiation does not affect a camera, it is made of metal, plastic and glass. Some radiation can affect film. The film is kept in cassettes, which are made of metal and can shield it against most forms of radiation. These cassettes are stored in spacecraft, which provide further shielding. Shorter still, radiation is light, and cameras are designed to be light proof.

Having said that, I'm not sure how they could coat the lens in silver (or gold, or lead) and expect to take pictures


It means the metal lens barrel, not the glass lens elements. Although they could have a thin layer on the glass element - not sure it would do much good though.

I have to introduce you to the "Kodak Wratten 87 IR" filter then(Aeolus1970);

When Infrared film was being produced( all film is somewhat sensitive in the infrared range; this film was specifically aimed at that band. ) the film was also sensitive(reacted)to visible light.

So Kodak produced a filter to cover the lens blocking visible lightbut made to pass the ir frequencies(wavelengths).

Yes, it was completely "opaque" (black) to look through.You could focus the camera by "setting the distance using the"infrared focus mark" on the lens barrel point the camera, and take the photograph.

We learned if you put the flexible "Wratten" gel filter material(plastic)over a camera flash it would fill a pitchblack darkened room with IR and produce no visible flash.but take great b&w IR pictures.
