Year denotes year of membership. Names of States are not necessarily their historical designations.
The Democratic People's Republic of Korea (DPRK), which joined the IAEA in 1974, withdrew its membership of the IAEA in 1994.
For States in italics, membership has been approved by the IAEA General Conference and will take effect once the State deposits the necessary legal instruments with the IAEA.
