The Centre for Disease Control (CDC) said a national panel was meeting imminently to discuss preparations that needed to be made in the case of an apocalyptic nuclear blast.
This announcement comes just days after US President Donald Trump bragged about the effectiveness of his “Nuclear Button” – in response to North Korean provocation.
The public forum, scheduled to take place on January 16th, will address “planning and preparations” for the country in the event of a nuclear strike.
Former Vice President Joe Biden said in recent days that the US has never been closer to nuclear war with North Korea.

“Despite the fear surrounding such an event, planning and preparation can lessen deaths and illness.”
The agency admits most people “don’t realize that sheltering in place for at least 24 hours is crucial to saving lives and reducing exposure to radiation”.
President Trump and the North Korean regime have been engaged in an escalating battle of threats and a war of words over nuclear confrontation.
Kim Jong-un has even claimed that a nuclear bomb in his country can now easily reach Washington DC.
In response, Mr Trump has threatened to “totally destroy” the country with a population of 25million people.
International Relations and Foreign Policy Expert Jim Scott told ABC: “Although this has been planned since Spring 2017, and not a knee-jerk response to the President’s tweets, the publicized effort of it suggests experts feel there is a heightened concern.
“This comes quick on the heels of US security personnel noting that we are closer to nuclear confrontation with North Korea than ever before.
“We were once well-informed during the Cold War but once that ended, we stopped talking about it or teaching it in schools.
“You would be hard-pressed to find someone on the street who knew what to do in the event of a nuclear blast.”
Jeffery Lewis, a nuclear policy expert, added that “there would be survivors for days trying to make their way out of the rubble and back home, dying of radiation poisoning”.
