Frédéric Joliot-Curie, the son-in-law of Marie Curie, even mentioned it in his Nobel Prize speech, delivered in 1935 after he and his wife, Irène, discovered a way to cause radioactive decay to occur in otherwise non-radioactive materials, a phenomenon known as artificial radioactivity.

Or, on the other hand, radioactivity could bring about a dystopian nightmare in which, as Rutherford liked to say, "some fool in a laboratory might blow up the universe unawares" by inadvertently triggering a planetary chain reaction through some artificial radioactivity process.

We also see Marie’s pride in Irène’s own research on artificial radioactivity, which would win her and her husband Fréderic Joliot their own Nobel prize just a year after Marie’s death.

It found levels of artificial radioactivity in the mud were so low they would equate to being "not radioactive" in law.

At the Nobel Prize ceremony that December, honoring the Joliots for their discovery of artificial radioactivity, the presenter took a brief detour to mention Lawrence’s preparation of radiosodium and expressing the hope that “it can be used in the same way as radium salts in medical applications.”
