Atomic Radiation
Encyclopaedia Britannica Films
Men assembling cars on small assembly line. Atomic reactor w/ serveral men; man diagnosed by radiation; archaeological dig; man w/ geiger counter & others in field. Dissolve from pole in field to diagram.
15:41:31 Animated diagram showing atomic energy radiating out from pole. Atom w/ atomic field. Costumed depiction of Henri Becquerel in lab w/ assistant, discover photographic plate was exposed in the dark by uranium (without being triggered by sunlight). Diagram of atoms, of nucleus. Various radiations listed on chart.
15:43:37 Chart explaining alpha, beta & gamma & difference explained.
15:44:15 Pierre & Marie Curie experiment staged w/ photographic plate, a piece of radium in a metal block & strong magnetic field. Chart showing why beta goes to positive pole & alpha rays to negative pole. More of Curies.
15:46:01 Professor lecturing on uranium U-235 to science class. Explains how the neutrons are released in animated sequence.
15:48:12 Hydrogen bomb exploding. Reactor shown in still photographic & animated diagrams as to method of producing radio isotopes. Workers in protective mask, clothes & w/ tools & instruments to monitor work.
15:49:33 Polonium sample inserted to a measuring device & sheet of paper stops the slow moving particles. Radium E sample releasing beta particles which pass thru paper but not aluminum. Cobalt 60 pass thru paper, aluminum but not thick lead. Drawing showing what gets stopped.
15:50:45 Becquerel & assistant. Diagram of cosmic, natural & artificial radiatiiion shown. Use of radiation in medicine, agriculture shown.
