https://peertube.dngr.us/videos/watch/1a8e2e39-e6c6-4109-a8e0-72302f853eec Produced by the Home Office and the Scottish Home Department in 1960, "Radioactive Fallout // The Overall Situation" and "Fallout in the Affected Area" give a chilling idea of what might happen if the United Kingdom were struck by nuclear weapons. A simple mushroom shown on the ground quickly becomes a mushroom cloud, and so the story unfolds -- with fallout moving quickly across a large swath of England. Nuclear fallout, or simply fallout, is the residual radioactive material propelled into the upper atmosphere following a nuclear blast or a nuclear reaction conducted in an unshielded facility, so called because it "falls out" of the sky after the explosion and shock wave have passed. 00:00 - Bright, peaceful day hints at underlying threat. 1:02 - Sun shines, birds sing, unaware of devastation. 1:21 - Nuclear weapons cause fire, blast, fallout. 1:42 - Radiation is undetectable by senses. 1:56 - Film aims to teach survival during nuclear attack, reduce radiation sickness. 2:18 - Radiation hazards 2:26 -Danger from 10 megaton blast within 2.5 miles. 2:42 - Residual radiation a lingering threat beyond Ground Zero. 3:01 - Radioactive dust. 3:19 - Beta, gamma rays 4:00 - Beta rays stopped by clothes, gamma penetrate deeper. 5:00 - Gamma rays cause damage over time. 5:08 - Radiation measured in "runin." 6:00 - Emergency radiation dose set at 75 runin. 6:30 - Fatality rates linked to radiation doses. 6:48 - Protection via distance, screening, decay. 7:19 - Radiation reduced by distance from source. 7:50 - Walls, materials offer screening. 8:00 - Radiation weakens over time like a cooling poker. 8:19 - Decay rates of radiation. 9:01 - Two-story houses reduce radiation. 9:29 - Cellars, trenches provide extra safety. 9:45 - Single-story homes offer less protection; improve isolated two-story houses. 10:00 - Larger, solid buildings with few windows best for protection. 10:14 - Convert rooms with one outside wall to refuge. 10:20 - Block windows, fill with earth. 10:32 - Enhance safety with sandbags, earth-filled boxes, furniture. 10:45 - Slit trenches in foundations; seek advice. 11:01 - Garden trenches with cover good too. 11:07 - Avoid sites prone to debris. 11:17 - Prepare for days in refuge. 11:27 - Earth, concrete cover offers protection. 11:45 - Stay in refuge for days post-fallout. 11:59 - Short refuge exits for essentials; prep in advance. 12:27 - Keep food, water, radio, sanitation for a week. 12:55 - Apply radiation knowledge post-blast. 13:11 - High radiation upwind, crosswind from Ground Zero. 13:32 - Weather influences contamination patterns. 13:55 - Larger downwind fallout area. 14:06 - Fallout extends 500 miles downwind, 100 wide. 14:27 - Fallout could cover half of Europe 14:41 - Warnings issued by sector operations centers. 15:19 - Meteorology aids in forecasting fallout. 15:30 - Warning Gray for incoming fallout, hour+ warning. 16:00 - Time for final preparations with Gray warning. 16:27 - Warning Black when fallout imminent; immediate refuge. 17:01 - Black warning if national alerts fail. 17:40 - Reorganize plans for other weapon fallout. 18:11 - Two areas: damaged around Ground Zero, larger fallout zone. 18:56 - Big bombs explode near ground for more fallout. 19:16 - Destruction zones A, B, C, D within 20 miles. 20:00 - Challenges with warning systems, casualties. 20:19 - Lethal fallout in open in zones A, B. 20:24 - Protecting from fallout. 20:47 - Survivors need emergency supplies, stay covered for days. 21:00 - Hard to assess outside; use radios for updates. 21:17 - Life-saving teams face challenges 21:45 - Fire damage might necessitate alternative shelters. 21:53 - Take cover when dose rate nears three runin/hour. 22:01 - Local alerts based on radiac readings. 22:14 - Teams directed to lower dose areas upwind, crosswind. 23:02 - Wardens, controllers limit exposure to 75 runin. 24:20 - Teams work 8 hours at 10 runin/hour before withdrawal. 24:30 - Dose rates reported for plotting on maps. 26:02 - Relief arrangements for teams at 75 runin. 26:21 - Operations might extend dose to 100 runin if necessary. 26:33 - Emergency situations might require 75 runin in 4 hours. 27:03 - Teams move towards Ground Zero. 27:31 - Emphasis on self-help with rescue aid. 28:02 - Mapping fallout, action plans enacted. 28:08 - Survival depends on preparation, fallout protection.
