The American publication Newsweek has modeled the consequences of a potential nuclear bomb attack on North Korea, Russia and China.
A B83 thermonuclear bomb strike on Moscow could kill 1.4 million people and injure approximately 747,220.
For Beijing, losses could amount to around 1.5 million people, with around 3.3 million injured.

According to Newsweek , 1,327,820 people are expected to die in Pyongyang and 1,105,660 will be injured.
The radius of the fireball will reach 4.1 square kilometers. The inner circle of destruction will destroy residential buildings and, quite likely, lead to large-scale fires.
Anyone within the radiant heat will be at risk of third-degree burns, which can result in disability.
The authors of the paper suggest that the above estimates will depend heavily on how high the detonation occurs.
The model presented assumed that the detonation altitude was 3.32 kilometers.
