Atomic Gardening

In the 1950s and 1960s, people experimented with exposing plants to radioactive sources in order to create useful mutations.

The Atomic Gardening Society invited members to plant irradiated seeds in their garden, and report back on any interesting results. They also built "gamma gardens" – large, circular gardens with a retractable source of radiation in the middle, usually the isotope cobalt-60.

Two results that are persisting to this day is the resistance of a peppermint cultivar to a specific plant disease, and the Rio Star Grapefruit popular in Texas.
