States try to limit nuclear tests not only because they are harmful to the environment, but also because these tests mean that new nuclear weapon capabiltites are being developed. Since the end of WW2, there have been efforts to limit and ban further nuclear tests. A significant milestone was achieved in 1963 when the Partial Nuclear Test Ban Treaty was signed. According to it, the member States have to stop testing nuclear explosions on the atmosphere, underwater and in outer space (under ground test were excluded from the Treaty). The most recent effort to ban all testing was the 1996 Comprehensive Nuclear Test Ban Treaty, which prohibits all kinds of testing, even underground. The CTBT is not yet in force due to the lack of some ley State's ratifications (namely the US, China, North Korea, Egipt, India, Pakistan, Iran and Israel)
