Although New Zealander Lord Rutherford was the first to split the atom, the country has since been known around the world for its nuclear-free stance. In this engaging and accessible book, an alternative history is revealed of "nuclear New Zealand"—when there was much enthusiasm for nuclear science and technology. From the first users of X-rays and radium in medicine to the plans for a nuclear power station on the Kaipara Harbour, this account uncovers the long and rich history of New Zealanders' engagement with the nuclear world and the roots of its nuclear-free identity.
