...aand 100% kill probability distance could be???? About a mile maybe?
100% kill is approx ~2400m radius from the Epicenter, caused by the Air Blast Shock Wave.
Within ~80m radius, all object will instantly disappear, due to the Nuclear Fireball.
I have not calculated Thermal Radiation (Burn, Flash) and Nuclear Radiation yet, but I expect these has minor effect, compared to the Shock Wave.
