A simple graphic showing comparative nuclear fireball radii for a number of different tests and warheads. From largest to smallest, the diameter are:
<ul><li><a href="https://en.wikipedia.org/wiki/Tsar_Bomba" class="extiw" title="en:Tsar Bomba">Tsar Bomba</a> — 50 Mt — 4.6 km (2.9 mi)</li>
<li><a href="https://en.wikipedia.org/wiki/Castle_Bravo" class="extiw" title="en:Castle Bravo">Castle Bravo</a> — 15 Mt — 2.84 km (1.76 mi)</li>
<li><a href="https://en.wikipedia.org/wiki/W59" class="extiw" title="en:W59">W59</a> warhead (<a href="https://en.wikipedia.org/wiki/Minuteman_missile" class="extiw" title="w:Minuteman missile">Minuteman missile</a>) — 1 Mt — .96 km (0.60 mi)</li>
<li><a href="https://en.wikipedia.org/wiki/W88" class="extiw" title="en:W88">W88</a> warhead (<a href="https://en.wikipedia.org/wiki/Peacekeeper_missile" class="extiw" title="w:Peacekeeper missile">Peacekeeper missile</a>) — 350 kt — .64 km (0.4 mi)</li>
<li><a href="https://en.wikipedia.org/wiki/Fat_Man" class="extiw" title="en:Fat Man">Fat Man</a> bomb (dropped on <a href="https://en.wikipedia.org/wiki/Nagasaki,_Japan" class="extiw" title="w:Nagasaki, Japan">Nagasaki, Japan</a>) — 18 kt — .2 km (0.1 mi)</li></ul>
Note that these are only for the fireball component of the explosion — <a href="https://en.wikipedia.org/wiki/Nuclear_fallout" class="extiw" title="en:Nuclear fallout">radiation</a>, <a href="https://en.wikipedia.org/wiki/Explosion" class="extiw" title="en:Explosion">blast</a>, and <a href="https://en.wikipedia.org/wiki/Thermal_radiation" class="extiw" title="en:Thermal radiation">heat</a> would extend <i>far</i> beyond these distances (i.e. for the Tsar Bomba, anyplace with 6.56 km would receive 500 rems of radiation, there would be near total fatalities for the air blast within 9.95 km, structural damage at 26.26 km, and third-degree burns at 58 km). This is meant only to give some means of comprehending the differences in scale between different weapon designs.
