decontamination of hands contaminated with liquid radioactive material Posted by: bionerd23
Video duration: 484 seconds this is a rather harmless experiment with just 5 MBq of Tc-99m. only a tiny fraction ends up on my hands, and there's virtually zero whole body dose from this... plus the physical half life is just 6 hours. DO NOT TRY THIS with your radium watch hands or other long-lived, biologically active radioactive material! |

chernobyl 2012: albedo personal dosimeter dose report (vs. brazil holiday radiation) Posted by: bionerd23
Video duration: 954 seconds albedo dosimeter? how does it work? see here: http://flic.kr/p/bJM rW6 ...and if you just want to know the facts: i received ~100 uSv during 2 days of staying in chernobyl, but ~240 uSv while spending 2 days on the tourist beaches of brazil. |

chernobyl 2012: the red radioactive forest (????? ???) Posted by: bionerd23
Video duration: 117 seconds the pine trees in this forest turned brown as they died from the intense levels of radiation after the chernobyl disaster. the whole forest was torn down; now, fresh trees are growing on the still quite radioactive grounds, seemingly without problems. |

chernobyl 2012: the jupiter plant (officially a radio factory) Posted by: bionerd23
Video duration: 201 seconds not much radiation here - hardly above ambient levels in europe. it's but an intermission, displaying the true physical hazards of the "zone" - condemned buildings and wildlife. |

chernobyl 2012: the exclusion zone, the reactor and the sarcophagus Posted by: bionerd23
Video duration: 208 seconds maps of the exclusion zone as well as views of the reactor of chernobyl from different angles... and from up close. radiation levels in front of the reactor building: harmless. much stronger radiation is to be found off-site... i'll talk about it later. |

chernobyl 2012: the kindergarten of ?????? (kopachi) Posted by: bionerd23
Video duration: 184 seconds ?????? was a small village near chornobyl. it was entirely torn down as it was heavily contaminated... only the kindergarten - which was too solid to tear down quickly - remained... nowadays, the radiation levels here are minor. the zone provides much stronger stuff... |

brazil 2012: quantitative gamma spectroscopy Posted by: bionerd23
Video duration: 66 seconds we know that there's a lot of Thorium-232++ and some Uranium-238++ in the natural monazite sand from brazil. but just how MUCH is there, in terms of an activity in becquerel (decays per second) per kilogram? well... let's find out. :) |

how to make afternoon tea (for nerds) Posted by: bionerd23
Video duration: 66 seconds would you like a cube of neodymium in your cup of superconductor, dear? recipe: - put YBa2Cu3O7 disc into cup. - add boiling liquid nitrogen. - let stand until supercooled. - add cubes of neodymium to taste. ...and no, this is not an april's fool. just google for "yttrium barium copper oxide". |

brazil 2012: albedo dosimeter reading (gamma + neutron dose) Posted by: bionerd23
Video duration: 211 seconds total dose received within 5 days: approx. 0.5 mSv. that is about half a year's worth of gamma radiation in europe. |

experiments with the liquid metal mercury V (feat. gallium) Posted by: bionerd23
Video duration: 380 seconds mercury in HD and high FPS (slow motion) video. Hg, or quicksilver, is the only metal to be liquid at room temperature (20 degrees celsius) and standard pressure. note: slow motion video parts could sadly not be recorded in HD. |

linear accelerator turns geiger counter radioactive! (photonuclear reaction and neutron activation) Posted by: bionerd23
Video duration: 794 seconds quite amazing to see how an 18 MeV photon beam in one meter distance for ~30 seconds (for a dose of 1 Gy in 1 meter from beam focus) is capable of turning my poor gamma scout RADIOACTIVE! :D |
