Furthermore, snow and rain can accelerate the local fallout. For example, the Castle Bravo surface burst at Bikini Atoll on March 1, 1954, affected the Pacific Ocean and its islands, extending over 500 km downwind and 100 km varying in width. Atmospheric winds can bring fallout to far and large areas. On the other hand, meteorological conditions can also affect fallout. On March 1, 1954, scientists conducted a hydrogen bomb test at Bikini Atoll. The fallout from seawater is difficult to remove. Meanwhile, when the nuclear weapon is detonated on water (water surface burst), it will produce less local fallout, extending to a greater area. If a nuclear weapon is detonated in the air (air bust), it will produce less fallout than those detonated near the ground. The height and the surface composition determine the location of an explosion. Those that deposit first is the less volatile elements. The larger particles will pour out of the stem, and nuclear fallout will arrive near ground zero, possibly within an hour.
When a surface bursts, it can produce a huge amount of particulate matter. Some radioactive products affect vast land and bodies of water which causes a mutation in human and animal life. This material will turn into a radioactive contaminant as it condenses with fission products that turn to become neutron-activated. Local fallouts are intense, but it is short-lived. On the other hand, during a local fallout, the heat can vaporize a huge amount of water from the water surface burst and drawing up to form a radioactive cloud near the site of the explosion. This can be through eating foods that contain radioactive materials. The global fallout can bring radio-biological hazards in human beings due to the potential accumulation of lived radioisotopes, like the Caesium-137 and Strontium-90. The fallout would be dispersed worldwide through atmospheric winds and settle on the world's surface after days, weeks, months, and years as global or worldwide fallout.
Then, these particles will be stuck in the stratosphere. Fission products and nuclear residues will condense into a fine suspension of small particles during a worldwide or global fallout.
