WHAT TO DO IF THERE IS A NUCLEAR EXPLOSION?!
 
07:08
Try Dashlane here: https://www.dashlane.com/infographicsshow (Plus, here’s a promo code: infographics) Imagine this: A sudden bright light followed by the sounds of the heavens opening. An intense heat blast smashes through the city and a gigantic mushroom cloud slowly rises. Cars swerve from the roads amid the screams of fear, panic, and pain. And that’s only if you have enough time to see the spectacle, before being blasted off the face of the earth. It’s an apocalyptic image alright, but would a nuclear blast really spell the end of the world? Are there any steps that we could take in advance to avoid frying as the nuclear device is detonated in our home city? That’s what we’ll find out, in this episode of The Infographics Show, How to Survive Nuclear Fallout.

25 STRANGE Things That Have Happened In Space

The strange things that have happened in space will shock you. These weird space stories will surprise you and make you think twice about what is hiding in the sky above us. What space secrets is NASA hiding from us? What real astronaut stories have you never heard? Check out these 25 strange things that have happened in space to find out! Space is the last great mystery for explorers around the world. You would never guess, but there are countless stories of the strange and unexplained from those who watch the sky and the astronauts who have lived above the Earth. In the dark cold of space, the sights and sounds are down right alien. Watch these strange things that have happened in space (and our photo credits and sources) and be sure to leave us a comment below telling us which stories you believe and which are too out of this world: https://list25.com/25-strange-things-that-have-happened-in-space SUBSCRIBE - http://bit.ly/2uwq6BJ Follow us on: List25 Facebook - https://www.facebook.com/list25 List25 Instagram: https://instagram.com/list25/ List25 Twitter - https://twitter.com/list25 List25 Pinterest: https://www.pinterest.com/list25/ See more lists on our website: http://list25.com As brave space explorers, astronauts have to tolerate their bones weakening and their eyes changing but no one expected they would see ghostly lights or hear otherworldly music in space. Even stranger is the chilling stories of exploding objects, space eels, and strange spacecraft caught on NASA footage. These NASA secrets are just as weird as the things astronauts did on purpose, like bringing contagious bacteria into space and turning it into super bacteria or lighting a fire to see what burned. Of course, who can forget the strange UFOs caught on camera in space. See all these and more in this video of 25 strange things that have happened in space.

The Most Radioactive Places on Earth
 
11:18
Who on Earth is exposed to the most ionizing radiation? Check out Audible: http://bit.ly/AudibleVe I'm filming a documentary for TV about how Uranium and radioactivity have shaped the modern world. It will be broadcast in mid-2015, details to come. The filming took me to the most radioactive places on Earth (and some places, which surprisingly aren't as radioactive as you'd think). Chernobyl and Fukushima were incredible to see as they present post-apocalyptic landscapes. I also visited nuclear power plants, research reactors, Marie Curie's institute, Einstein's apartment, nuclear medicine areas of hospitals, uranium mines, nuclear bomb sites, and interviewed numerous experts. Notes about measuring radiation: Sieverts are a measure of 'effective dose' - that means they measure the biological impact of the energy transferred to tissues from radiation. Obviously I owe a debt to the fantastic chart made by xkcd, which inspired my visual approach to this video. https://xkcd.com/radiation/ DOSES MAY VARY The level of radiation varies widely around the world depending mainly on altitude and geology (excluding nuclear accidents). Estimates of particular doses also vary. All numbers reported in this video should be taken as order of magnitude only. The most contentious claim may be that smokers receive the highest dose of ionizing radiation. This is not a whole body dose, but a dose to the lungs as specified in the video.
