Three major things will get you in the nuke blast.
1.The Blast force that equals 50% of a nukes energy, depending how close you are and what is between you and the blast will determined your survival.
For the 15 kiloton nuke dropped on Hiroshima The area of total vaporization from the atomic bomb blast measured one half mile in diameter; total
destruction one mile in diameter; severe blast damage as much as two miles in diameter. Within a diameter of two and a half miles, everything
flammable burned. The remaining area of the blast zone was riddled with serious blazes that stretched out to the final edge at a little over three
miles in diameter.
Now we do have some around 5 megaton, but most of ours and the worlds nukes are 100k to 500k since the blast radius becomes increasingly harder to
expand and so a 5 megaton bomb blast is only a few times bigger than a 100 kiloton hence the small nukes are more efficient.
A one megaton weapon would cause 105 square miles of 3+ psi destruction and 8 low tech 20 kilotons detonated in a circle would caused even more
2. Fire Ball equals 35% of the nukes thermal energy. At Hiroshima, it has been estimated, solid materials on the ground immediately below the burst
probably attained surface temperatures of 3,000 to 4,000°C (5,400 to 7,200°F)." And as far away as 0.61 mile, they may have reached 1,800°C
(3,270°F). With a 250 Kt weapon such heat could readily extend from 1.1 to 2.6 miles; with 550 Kt it could be 2 to 3.9 miles. Thermal radiation from
a nuclear explosion ignited upholstery and caused fire to spread in this car at the Nevada test site.
3. Gamma Radiation, this is where your water comes into play to save you. You need about 10 feet of water to prevent the gamma rays from passing
through your body and killing cells. So, if you swim down and hold your breath a few mins and you’re outside the blast/fireball radius the water can
save your life. But one other thing is you will then need to get indoors quickly for the fallout partials will continue to have gamma radiation and
will continue to produce the radiation killing your cells if you do not have further protection between it and you.
