Oslo June 1962 After the Soviet start with nuclear test blasts, it has become necessary to control the content of radioactivity, such as the substances caesium and strontium 90 in i.a. milk. In the State Radiological physical laboratory at Ullern, Norway is radioactively mapped. Eight subjects are involved in the research, where four get syringes with radioactive caesium, while the other four eat reindeer meat containing radioactive fallout. Then the radioactivity is measured. Here Dr. Strømme takes a blood test of subjects and manager Kristian Koren, who has radioactive blood. Photo: Aaserud / Aktuell / NTB
