Fazal-ur-Rehman M and Sana Akram
All the Actinides (An) are not naturally produced elements, rather most are artificially synthesized by radioactivity (Ra) of some parental and by bombardment of alpha, beta or gamma particles. After bombardment, parental and the decayed radiations are generated or synthesized. However, the parental An are found in natural metal ores. The other An are not just synthesized by Ra of parental An, but also present in radioactive wastes of other metals.
