This paper extensively explores the topic of detection, use, and consequences of nuclear weapons. It encompasses an overview of key aspects of nuclear weapon development, their applications, and the profound repercussions stemming from their utilization. Nuclear weaponry is the outcome of scientific and technical endeavors culminating during World War II. Throughout history, nuclear arms have played a pivotal role in international relations and geopolitical dynamics. Their deployment in Hiroshima and Nagasaki forever altered the course of history, marking the onset of the atomic age. Beyond military application, nuclear weapons carry profound societal and political implications. The aftermath of nuclear weapon use is reflected in devastating effects on human lives and the environment. Radiation emanating from nuclear detonations triggers long-lasting health consequences, including an increased incidence of cancer and genetic mutations. Environmental impacts encompass radioactive contamination that disrupts ecosystems and biodiversity. Despite international efforts to prevent nuclear proliferation, it remains imperative to take steps toward disarmament and raising awareness about the catastrophic consequences nuclear weapons can bring.
