North Korea nuclear test: How would a radioactive cloud spread across the Pacific? - TomoNews

NORTH KOREA — A new graphic shows the effects an atmospheric burst would have if North Korea were to carry out a nuclear test over the Pacific Ocean. The simulation of the radioactive cloud spreading for two weeks across the globe was posted by Lassina Zerbo, head of the Comprehensive Nuclear Test Ban Treaty Organization, on Twitter. The graphic did not include any supporting data such as nuclear payload or height of detonation, the Telegraph reported. Experts say the explosion, fire and radiation created from a hydrogen bomb test over the Pacific Ocean could have catastrophic effects. Aquatic life in the immediate blast zone would be killed instantly, while radioactive isotopes — with the help of wind — could impact other organisms and humans thousands of miles away.
