How To Survive The First Hour Of A Nuclear Blast / Fallout!

The situation has played out in TV and movies for years, but what should you really do if a nuke detonated near
you?
Will the fireball automatically obliterate...

It’s highly unlikely to shoot down a missile mid-air. But there's more to it than that! Causing a nuclear bomb to detonate requires a precise orchestration of events, without which the chain reaction does not initiate and the bomb...

This video is a lecture that explains the concept of background radiation, which is a type of ionizing radiation that humans are exposed to every day but at low levels. The video discusses the four main types of ionizing radiation, which...

A nuclear blast is about to detonate! Where do you hide?!<br/>
Indiana Jones opted for a lead lined fridge and survived, but just how safe would it really be?

This video covers the history of the Trinity nuclear test in 1945, revealing how radioactive fallout from the explosion was unintentionally detected by Kodak through exposed film. It explains the impact of fallout on public health,...

In a nuclear explosion, how close you are impacts your chance of survival. But who you are also has more influence than you might think. If everyone on Earth were equidistant from the bomb, here's the last person...

If you want to be prepared for a nuclear attack, here’s a science-based guide to help you get there.

Nuclear weapons are the most destructive things we’ve ever created, but it turns out there’s a way to make them even deadlier…

If a nuke exploded in space, gamma rays and X-rays would be emitted and would expand to light up the sky. On the surface of the planet, auroras of light would be seen for thousands of miles within minutes of the blast. The explosion...

When scientists at the top secret 'Manhattan project' wanted to discover how radioactive bomb materials could affect the human body – they secretly injected terminally ill patients with uranium to find out.

France conducted 193 nuclear tests not far from Tahiti, exposing the local population and French soldiers to high levels of radiation. <br/>

Radioactivity. We've seen it in movies, it's responsible for the Ninja Turtles. It's responsible for Godzilla. But what is it? It's time to learn exactly what nuclear reactions are, and what it is that makes atomic bombs so destructive,...

At the start of the 20th century scientists had a good estimate of how old the Earth was. At least several billion years of age. This led to the tricky question as to how the Sun not only generated heat and light, but how it had done...

Although radioactive materials are associated with power stations and bombs, we live with radioactive substances all around us. What are they, and do they affect us?

When scientists first split the atom, they didn’t realize what they’d done until physicist Lise Meitner figured out they had discovered what we now call nuclear fission.

When the Americans tried to detect radiation from Soviet bombs, they in fact discovered gamma ray bursts - radiation from deep space. Physics - Universe - Learning Points. During the Cold War, the US suspected the Soviets of testing...

What happens when you set off a nuclear bomb in space? Turns out we have a pretty good idea, and it's not pretty. Learn about the science behind high-energy explosions in space.

In 1954, the US Government conducted a series of secret nuclear tests in the Marshall Islands. The idyllic coral island Bikini Atoll became the epicentre of the largest nuclear test disaster in US history. The affects of radiation...

if you took a notebook, a plastic bottle, a toaster, and a glass container and burned them in a fire hot enough, around 10^31 degrees Celsius, all the particles and forces, would become one entity. This is what...

Some of the greatest advances in science have come from humanity's more destructive impulses. This is not the fault of science - when we discover powerful truths about the universe it's up to us to decide how to use them because...
