BIKINI BLASTS is a term used to describe the process of testing nuclear weapons in the atmosphere. ATESTS and NTESTS are two types of tests that are conducted as part of this process. ATESTS stands for Atmospheric Tests, which involve detonating a nuclear device in the atmosphere, while NTESTS stands for Nuclear Tests, which involve detonating a nuclear device underground. Both types of tests are used to measure the effects of nuclear explosions on the environment and to assess the safety of nuclear weapons.
