Duck and cover
![1954 test shot Nectar of Operation Castle produced a yield of 1.69 megatons and was conducted off the coast of Teiter island. Note the distinctive near instantaneous double flash, with the second appearing brighter than the sun, and the blast wave slowly, by comparison, spreading out turning the calm ocean water a frothy white when it arrives. The maximum average nuclear fireball radius is approximately 1.4 to 1.6 km (0.87 to 0.99 mi).[28][29] The outdoor blast and flash burn LD50s would be around 8 and 12 km respectively.[28][30] Assuming personnel did not take any prompt countermeasures, instead standing still absorbing the entire light energy emitted over the ~20 seconds of emission.](/uploads/202501/10/-Operation_Castle_-_Nectar_-_Detonation.ogv1628.jpg)
"Duck and cover" is a method of personal protection against the effects of a nuclear explosion. Ducking and covering is useful at conferring a degree of protection to personnel situated outside the radius of the nuclear fireball but still within sufficient range of the nuclear explosion that standing upright and un-covered is likely to cause serious injury or death. In the most literal interpretation, the focus of the maneuver is primarily on protective actions one can take during the first few crucial seconds-to-minutes after the event, while the film by the same name and a full encompassing of the advice, also caters to providing protection up to weeks after the event.
