Russia Mass-Producing Nuclear Bunkers That Protect Against Shockwaves & Radiation

Russia has started mass producing mobile bomb shelters that can protect against a variety of threats including shockwaves and radiation from a nuclear blast.
The emergency ministry's research institute said the "KUB-M" shelter could offer protection for 48 hours against these and other natural and man-made hazards.
Among those it listed were: explosions and shrapnel from conventional weapons; falling debris from buildings; dangerous chemicals and fires.
The 'KUB-M' mobile bomb shelters look like reinforced shipping containers and consist of two modules - a room for 54 people and a technical block.
They can easily be transported on a truck and connected to water supplies and can also be deployed in Russia's vast northern permafrost.
The move has not been linked to any current crisis, however Ukraine just launched U.S. provided long range missiles into Russia, Putin lowered the threshold for nuclear strikes and said he would respond to the latest attack.
