Your right, too many zeros. 50 MT
3rd degree burns estimated at the 100km (65 miles)mark. Shock wave 465 miles. The blast wave circled the earth 3 times.
I did estimate 80 miles as a somewhat distance to not experience damage.
But the 50-MT device was not a practical weapon. Even 10-MT weapons have been retired. More effective to use multiple lower-yield weapons, once delivery accuracy improved. "Damage" depends on overpressure tolerance, or bare skin.
