ABSTRACT
In the tropical rain forest of the Luquillo Mountains of eastern Puerto Rico, Radioecology research was carried out, led by Howard T. Odum, starting in the early 1960s. The impact to the forest from a stationary gamma irradiation source and the recovery of the forest after the source was removed were recorded. Although the original irradiation experiment lasted for only three months, ecological research has continued to the present at the site of the original radiation experiment, making this forest one of the best-understood ecosystems on the planet.
