Calculator, Nuclear Yield M4A1

This calculator is used to estimate the kiloton yield  of a nuclear weapon based on measurements of the time in seconds from the flash to the bang, the observed width of the cloud,  the distance to ground zero,  the fireball illumination time, and the elevation angle.

The M4A1 is included in the  U.S. Army M28A1 RADIAC calculator set.
