Encyclopedia Britannica Films presents, “Atomic Radiation”. Produced by Encyclopedia Britannica Films, in collaboration with the division of the physical sciences which includes the Institute of Nuclear Studies and the University of Chicago. Produced by Warren P. Everote. This is a 1950’s era, black and white film. The purpose of the film is to explain atomic radiation, its discovery and how it is being harnessed in the modern day and for what purposes. The film opens with two men digging at an archaeological site. Men are seen walking through a farm, :45. Atomic symbol is shown 1:00. The French chemist and physicist, Henri Becquerel 1:05. Becquerel and his assistant work together with simple, early experiments with uranium crystals, 1:25. Becquerel puts the uranium crystals in a drawer, 1:45. Henri V’s assistant develops the plates containing the crystals 1:53. The radioactive uranium gives off energy in light or darkness 2:00. Becquerel names this property of the uranium, radioactivity 2:20. Animations of Atoms and radioactive symbols are shown 2:37. Radiation animation with scientific terms is shown 3:00. Alpha Beta Gamma animation is shown 3:15. Pierre and Marie Curie, discoverers of radium are shown in their laboratory 3:50. Pierre Curie is shown conducting an experiment with radium 4:05. The experiment is discussed with alpha and beta particles and finally – the gamma rays 4:55. Gamma Ray animation 5:20. A professor stands in front of a blackboard explaining atomic energy 5:45. Animation shows Uranium – 235 in action 6:42. Animation showing fission is shown 7:00. The splitting of neutrons is shown in animation 7:40. Actual nuclear explosions 8:00. Animation of a nuclear reactor 8:15. Animation on radioisotopes 8:40. Scientist works carefully with uranium and other radioactive materials 8:48. Radiation detectors are shown 9:11. A Geiger counter is used to detect radiation 9:22. Radium E 9:48. Cobalt 60 10:03. Animation shows how different substances can stop alpha, beta and gamma rays 10:33. Radioactive animation 10:47. Health physics department is shown 11:20. Man in a hospital bed 11:37. Radiation is energy given off by matter in the form of rays or high-speed particles. All matter is composed of atoms. Atoms are made up of various parts; the nucleus contains minute particles called protons and neutrons, and the atom’s outer shell contains other particles called electrons. Electromagnetic radiation emitted by an atom as a result of its orbital electrons passing from a higher to a lower energy level.

Antoine Henri Becquerel (15 December 1852 – 25 August 1908) was a French engineer, physicist, Nobel laureate, and the first person to discover evidence of radioactivity. For work in this field he, along with Marie Skłodowska-Curie (Marie Curie) and Pierre Curie, received the 1903 Nobel Prize in Physics. The SI unit for radioactivity, the becquerel (Bq), is named after him
