Answer 1

The cloud chamber was about the first way of making radiation visible, and having done that you could use a camera to take pictures of the effect.

> Cloud chambers were invented in the early 1900s by the Scottish physicist Charles Thomson Rees Wilson. They played a prominent role in experimental particle physics from the 1920s to the 1950s, until the advent of the bubble chamber.
