This 1957 film "The Petrified River" describes the pursuit of uranium prospecting in the West. It details the process of mining in Colorado; beginning with prospectors in the air and following miners down. The film presents various uses of radioactive isotopes at Oak Ridge National Laboratory. Uranium is commonly used to generate heat in nuclear power reactors and produce nuclear fissile material for nuclear weapons. The film details the complex process of irradiating food supplies. It is presented by the Union Carbide Corporation; a chemical company founded in 1917. Union Carbide is attributed with developing an economical way to make ethylene from natural gases and liquids leading to the birth of the modern petrochemical university. It opens on the seal of the Department of the Interior, Bureau of Mines (:08). A plane sweeps over rocky terrain of Colorado, Utah and New Mexico (:17). Ancient rivers cut under the mesa’s containing uranium (:30). This film is from the Library of the Bureau of Mines of the US Department of the Interior (:51) and is presented in cooperation with Union Carbide Corporation (1:04). A brief history of the environment here is featured (1:25). Salt flats (1:45) blanket the land. The highlands of Colorado and New Mexico lay under light cloud coverage (1:57). Cascading waters cart silt and gravel to the flats (2:16). Layers of red and grey rock run across the red mesa lands (4:10) two hundred million years old. The pilots search for petrified river beds bearing Uranium (4:23). Equipment such as the scintinallator (4:30) is used to search for radiation. The cruiser uses a technique known as rim flying (4:41) around the Colorado plateau. A prospector scales the rock face seeking yellow rock containing uranium (5:03). He uses a Geiger counter (5:27). Survey markings are etched onto stakes (6:12). The process of scribing a claim (6:14) and notice are detailed. Bulldozers moves up the mesa wall (6:39) shoving rock aside. The drill sinks deep to drag up ore deposits (7:04). Drillers remove cylinders of stone (7:26). A radiation counter examines drill cores (7:53). An animation details how the earth miners operate (8:33). The drillers (9:12) dig into the rock face. Muckers scoop blasted free ore (9:35) into cars for the mine. Miner and cart slip into a tunnel (9:52). A compressed air engine pushes the miner along (10:12). A great shot follows the miner and cart down a narrow stone cave way (10:26). The cart emerges and cuts over a bridge (10:55).  Sediment is emptied into the back of a semi-truck (11:03). Trucks roll down mesa roads for buying stations (11:17). It arrives at Uravan (11:23), a plant operating from the 1940’s to the 1980’s. Ore is unloaded into receiving bins (11:40). Crushes pummel the rocks into a fine sediment (11:47). Rotating containers combine acid into the mix (12:14). The solution drips from the container (12:22). Liquids drip from sands in the rotating filters (12:45). Yellow cake remains (13:12). In the 1950’s the Atomic Energy Commission opened the plateau for drilling. A tank truck moves acid (15:18). An earth mover drags ore (15:22). The camera view pans around the mill (15:53). The hydrogen (16:22) and uranium atom are explored (16:59).  Nuclear fission is explained using animation (17:33). Men load a reactor with slugs of uranium (19:05). A radiation counter checks the ramrod for radioactivity (19:19). Materials are inserted within the reactor (19:35) and later withdrawn (19:44). A pharmacy technician stores products behind a thick wall (20:16). Various uses for radiation are discussed (21:23). A radioisotope is readied for delivery (21:47). Radioactive iodine is looked to (21:57). A patient takes a drink of the iodide mixed with water (22:48). A radiation counter moves over the patient’s body (23:01) seeking a diseased thyroid (23:13). Cobalt 60 is used (23:23) to locate a tumor. Food items are preserved by radiation (23:52). Samples are pulled from meat in order to test the application of radiation to prevent spoilage of food (24:09). Burros are used (24:45) in an experiment. Isotopes are explored to understand how cells utilize energy from the sun (25:15). Radiation is used for breeding experiments (25:18). Chromosomes are looked at under the microscope (26:04).
