In a short compass one can build working code from ground zero (scalar operations) up to exact calculation of generating functions and solutions of differential equations.
We would be starting from ground zero.
It is irrefutable that neutron doses at a distance of 40 km from ground zero at the time of detonation were zero.
They were told to bare themselves—they were virtually naked—and to roll on the ground at ground zero after various explosions.
As they were located at a mustering point at least 34 km from ground zero at the time of detonation, the dose from the flash radiation would have been zero.
There was found to be so little evidence of radiation that it was possible to play a game of cricket and to swim within one mile of ground zero.
As with conventional war, there is very little to be said that might help those who were at or close to ground zero of a nuclear explosion.
Members of the balloon unit were withdrawn to a safe distance of not less than 12·5 km from ground zero at the time of detonation.
