radioactive
Significado: Emitting or relating to the emission of ionising radiation or particles caused by the spontaneous disintegration of atomic nuclei. Figuratively, it describes a person, topic, or issue that is extremely controversial or politically toxic.
Radioactive is both a precise scientific term and a powerful figurative one. In science, it collocates with decay, isotope, waste, contamination, and material. In British journalism, 'radioactive' is used metaphorically to describe scandals, policies, or individuals too toxic for others to associate with — 'the policy became radioactive after the leaked report.' This figurative sense has grown markedly since the Chernobyl and Fukushima disasters intensified public awareness of nuclear hazards.
