Professor with a cow at University of Maryland experimental dairy farm in College Park, Maryland. Calves eating. A cow is injected with small dose of radioactive isotope to trace efficiency of feed conversion into milk. A professor takes milk sample from the cow. The milk is analyzed in a laboratory. Various laboratory instruments and Professors working with them.
Plant biologists working on an experimental peanut farm at the North Carolina State University, Raleigh, North Carolina. Scientists seek improved strains of peanuts resulting from irradiation of seed. Large sized peanuts are shown resulting from such experimentation. A boy is shown buying such peanuts from a street vendor. The boy opens his eyes wide at the large sized nuts.
Testing procedures that led to advent of fluoride treatment in dentistry for prevention of cavities. A boy brushing his teeth. In a laboratory, teeth that had made radioactive at the Oak Ridge National Laboratory, Tennessee, are subjected to mechanical brushing with stannous fluoride. A technician places a tooth in a Petri dish. He drops acid (akin to that produced by the human mouth which causes tooth decay) over the tooth, via a pipette. A woman technician using a Geiger counter, measures the amount of radioactive tooth dissolved by the acid. Experiment showed that the stannous fluoride reduced damage to the tooth caused by the acid.
A man with a briefcase gets off a airplane and sets his brief case down. A plastic sheet production factory and rolls of colored plastic being created with the aid of a "Atom Ray" thickness gauge used in manufacturing. An oil drilling site. Drilling core samples of rock are extracted from the bottom of the hole. They are collected and sent to laboratory in a van. The core samples are irradiated in a particle accelerator or atom smasher and the response of different elements in the samples is observed, providing information about their composition. Activity is recorded on paper and a needle moves over a graph during particle acceleration. Engineer shows an experimental well logging device that contains a radiation source for use deep in the hole to determine nature of the strata without having to remove a core. Geologists examine a graph. Engineers subject oil samples to bombardment by neutrons in a nuclear reactor. Test apparatus is lowered down in a water pool. It is anchored to a movable rack and water is filled in the pool. The test apparatus is moved into position beside the atomic reactor uranium core. The core goes critical and irradiates the test sample with neutrons. Control equipment is switched on. Red sign illuminates with message "Reactor on." The core glows. An engineer looks to observe the test apparatus. Another engineer operates control equipment in front of a General Electric Reactor Control panel. Summary of role of radioactivity in ordinary life, in medicine, food production, manufacturing, transportation, and the home. Exterior of a a nuclear reactor is shown beside power transmission equipment. A man in a hospital room receiving treatment from cobalt machine radiotherapy or radiation therapy. (External beam radiotherapy, or EBRT machine, also called a teletherapy machine). Several cows on a farm walking beside grain silos with a farm house nearby. A man applying stain or varnish to wood with a brush. A rack of automobile whitewall tires in a warehouse. A woman or housewife in a 1950s kitchen pouring coffee for a another woman. A van passes by a suburban house on a street in a 1950s American town and a mail man or post man delivers to the house. Scenes of a main street or downtown area in an American town or city.
U.S. Army soldiers move on road in vehicles and a military station wagon. They march with guns on their shoulders. They escort African American students (the "Little Rock Nine") from Little Rock Central High School, to the waiting car. The students enter the car. Driver is seen as the car leaves the school grounds.
"Little Rock Nine" African American students are escorted from Little Rock Central High School by armed United States Army 101st Airborne soldiers, and enter a Country Sedan station wagon under 'Operation Arkansas' in Little Rock. Soldiers board a jeep and follow the station wagon. Soldiers march and drill with guns in front of the school.
