U.S. Army M4A1 Nuclear Yield Calculator
|This calculator is used to estimate
the yield, in kilotons, of a nuclear weapon. It permits various measured
parameters of the explosion to be used: the time in seconds from the flash
to the bang and the observed width of the cloud; the distance to ground
zero and the observed width of the cloud; the fireball illumination time,
and; the flash to band time and the elevation angle.
The M4A1 is a component of the U.S. Army M28A1 RADIAC calculator set. Detailed information can be found in the FM-3-3-1 Field Manual.
