https://peertube.dngr.us/videos/watch/caefe0ed-f452-4ee1-ba16-034ed590cf4c Created by Cenco in 1961, this film discusses radioactive fallout and describes the types of radiation involved, how such radiation spreads, and how it affects living matter. Explains what is being done to understand and solve the problems associated with nuclear radiation. In this era, the health effects of fallout were not well understood. This film makes an earnest attempt to discuss fallout and makes several important points about how dangerous it can be. At this time public sentiment was building against nuclear tests. Just two years after this film was released, three (UK, US, Soviet Union) of the four nuclear states and many non-nuclear states signed the 1963 Limited Test Ban Treaty, pledging to refrain from testing nuclear weapons in the atmosphere, underwater, or in outer space. Underground testing continued for decades however. The film provides an overview of nuclear radiation, emphasizing the importance of understanding atmospheric contamination from bomb tests and the dangers of nuclear radiations. It explains how radioactive particles from nuclear tests enter the atmosphere and affect food and drink, alongside background radiation from natural sources. It covers exposure to internal and external radiation, the relative safety of man-made radiations from medical X-rays, and the cumulative effects of radiation. It discusses public awareness of radiation dangers from atomic explosions and fallout, detailing the types and their characteristics. It highlights the use of electronic devices and balloons to study radiation, concerns about biological damage from fallout, and the properties and threats of long-term Fallout, especially strontium-90. It underscores the importance of radiation control and monitoring, the impact of radiation on molecules and living cells, and the genetic mutations caused by radiation. The text concludes by noting the controversial nature of fallout studies, the lack of beneficial effects, and the need for caution and future scientific answers. 00:00: Introduction to the film series on nuclear radiation. 1:18: Importance of understanding atmospheric contamination from bomb tests. 1:36: Explanation of nuclear radiations and their dangers. 1:55: Radioactive particles from nuclear tests enter the atmosphere and affect food and drink. 2:18: Background radiation from natural sources like uranium, radium, and cosmic rays. 2:35: Cosmic rays' impact on atmospheric nitrogen and the food chain. 3:12: Exposure to internal and external radiation in living things. 3:45: Man-made radiations from medical X-rays and their relative safety. 4:15: Cumulative effects of radiation and the lack of a safe minimum level. 4:47: Public awareness of radiation dangers from atomic explosions and Fallout. 5:06: Types of Fallout: local, intermediate, and delayed. 5:38: Characteristics of local Fallout and its distribution. 6:13: Intermediate Fallout and its behavior in the troposphere. 6:45: Delayed Fallout in the stratosphere and its unpredictable descent. 7:07: Use of electronic devices and balloons to study radiation and air currents. 7:46: Concerns about biological damage from radioactive Fallout. 8:01: Review of alpha, beta, and gamma radiation types. 8:22: Alpha particles' low penetration and danger if ingested. 8:44: Beta particles' moderate penetration and internal danger. 9:14: Gamma rays' high penetration and external and internal danger. 9:45: Radioactive Fallout includes all three radiation types, with varying half-lives. 10:01: Long-term Fallout concerns, especially strontium-90. 10:33: Strontium-90's properties, half-life, and potential threat. 11:01: Permissible radiation dosage and background radiation's historical presence. 11:27: Radiation damage studies in animals and their relevance to humans. 12:01: Importance of radiation control and monitoring for atomic energy workers. 12:29: Radiation's impact on molecules and living cells. 12:54: Genetic mutations caused by radiation and their undesirable effects. 13:43: Fallout's small increase in background radiation and mutations. 14:28: Controversial nature of Fallout studies and lack of beneficial effects. 14:28: Need for caution and future scientific answers. Motion picture films don't last forever; many have already been lost or destroyed. For almost two decades, we've worked to collect, scan and preserve the world as it was captured on 35mm, 16mm and 8mm movies -- including home movies, industrial films, and other non-fiction. If you have endangered films you'd like to have scanned, or wish to donate celluloid to Periscope Film so that we can share them with the world, we'd love to hear from you.
