The idea of a 50-mile, twenty hour march developed from Kennedy's discovery in late 1962 of an executive order from Theodore Roosevelt, which challenged U.S. Marine officers to finish 50 miles (80 km) in twenty hours, spread out over a maximum of three days. [ 2][ 3] Kennedy passed the document on to his own Marine commandant, General David M ...

The NRC defines two emergency planning zones around nuclear power plants: a plume exposure pathway zone with a radius of 10 miles (16 km), concerned primarily with exposure to, and inhalation of, airborne radioactive contamination, and an ingestion pathway zone of about 50 miles (80 km), concerned primarily with ingestion of food and liquid ...
Earth radius (denoted as R 🜨 or R E) is the distance from the center of Earth to a point on or near its surface. Approximating the figure of Earth by an Earth spheroid (an oblate ellipsoid), the radius ranges from a maximum (equatorial radius, denoted a) of nearly 6,378 km (3,963 mi) to a minimum (polar radius, denoted b) of nearly 6,357 km (3,950 mi).

10-kilometre and 30-kilometre Zones. The Exclusion Zone was established on 2 May 1986 soon after the Chernobyl disaster, when a Soviet government commission headed by Nikolai Ryzhkov [ 8]: 4 decided on a "rather arbitrary" [ 6]: 161 area of a 30-kilometre (19 mi) radius from Reactor 4 as the designated evacuation area.
A nautical mile is a unit of length used in air, marine, and space navigation, and for the definition of territorial waters. [2] [3] [4] Historically, it was defined as the meridian arc length corresponding to one minute ( 1 / 60 of a degree) of latitude at the equator, so that Earth's polar circumference is very near to 21,600 nautical miles (that is 60 minutes × 360 degrees).
