Oslo - Norwegian and US researchers used radioactivity in castration experiments on psychiatric patients in Norwegian hospitals during the Cold War, the daily Dagbladet said yesterday.
Patients considered to be mentally retarded or insane were used as human guinea-pigs to test the biological and genetic effects of X-ray radiation on the body. Dagbladet said the experiments were carried out at the Gaustad, Rikshospital and Ullevaal institutions in Oslo during the 1950s and 1960s.
