Can someone please dumb down the basics of what would happen if North Kora(or anyone) were to launch a nuclear weapon at the mainland USA(assume they are 30 kilotonne bombs)?

If the bomb is detonated on the ground how large is the blast area? How big is the area affected by radiation from the explosion itself and how big is the area of the fallout. If I am 20 miles away downwind from the site what can I expect, what about 100 or 1000 miles away?

Then all the same questions for a bomb detonated in the air.

Assuming the best shelter we have is a brick room(with wooden roof) in the center of a cement basement. If we are 100 miles from the nearest explosion is that adequate protection? If so how long do we have to stay in there before moving the larger part of the basement?

I realize some of these questions may be stupid but do your best to help me understand.

fat man that hit Nagasaki was between 18-23kt

so you have plenty of history on what itl do and how it will affect a area.

20 miles away you will be fine might have some fallout to worry about.

and NK would become a glowing parking lot

Nukes are not detonated at ground level as it would largely ineffective, a 30 megaton nuke would likely wipe an entire city off the map if it detonated above the center of the city...you might survive the initial blast in you were in a basement but then the fallout would eventually kill ya...outside the blast radius would depend on which the wind was blowing as to where the fallout would go I'm guessing...

I will try.

If the bomb is detonated on the ground how large is the blast area?
Pretty small. A couple hundred meter radius.

How big is the area affected by radiation from the explosion itself
Deadly, immediate radiation around one kilometer radius.

and how big is the area of the fallout.
Again, small. Depends on the winds. Maximum radiation of the blast might be on the order of 30,000 R/hr, but that is very shortlived.

If I am 20 miles away downwind from the site what can I expect,
Perhaps 300 R/hr initially, which reduces at the rate of the 7/10 calculations.

what about 100
Would be around six hours or so at 15mph winds. The fallout radiation is already greatly reduced. Under 50 R/hr probably.

or 1000 miles away?
60 hours or so to arrive. Way down, less than 10 R/hr.

Then all the same questions for a bomb detonated in the air.
Deadly radiation radius would be less than a kilometer. There would be almost no fallout.
20 miles away and further, there would be very little direct and no fallout effects.


Assuming the best shelter we have is a brick room(with wooden roof) in the center of a cement basement. If we are 100 miles from the nearest explosion is that adequate protection?
If the floor above the basement is covered with some additional mass, such as dirt filled drawers, sandbags, or even just a few inches on the the floor, it would be fine.

If so how long do we have to stay in there before moving the larger part of the basement?
A maximum of two weeks, and probably only a few days, depending on the type of basement.

I realize some of these questions may be stupid but do your best to help me understand.
There are no stupid questions on this kind of subject if you have no previous information.

If you need some additional guidence, feel free to ask.

Just my opinion.

Here is a piece of history: the commies let some western sciences travel to Chernobul a week later after the event. There were hot spots 70 miles down wind with about 300R (recorded a week later), so the initial readings would be in thousands of REMs.
One has to understand that the fallout would not be uniform, but would extend narrow long "fingers" very far downwind (which itself could change), while many areas at the same distance would show much lower reading. And the picture gets muddier: right at the house the fallout at one corner can be many times greater than at another corner, due to local winds and precipitation. Worse yet, the shelter itself may have uneven protection (hot spots). this is especially likely for improvised shelters. All of this makes radiation meters essential.

Can remember the name of the site, someone may have posted here. But it's a site you can enter your location (or any location) and it'll show you the blast radius and all other pertinent info.

Try googling something like "nuke blast radius map".

There's a sticky at the top of this subforum with mapping tools. The one TRyan is thinking of is Nukemap. http://nuclearsecrecy.com/nukemap/

I'm using that for airburst data and HotSpot (and a few other non-public resources) for surface burst info.

You know there's the possibility they could use something larger now right? Because their last test was estimated to be between 120 and 150kt. So let's use 150kt just to be safe.

rough plot for protection from a frame house or building.


150kt burst (or 5 30kt's in roughly the same area)

Prompt radiation and blast effects are all limited to <2 miles for both (air burst 5psi range is about 2.3 miles). Thermal is ~3.5 miles.

150kt surface burst:

@20 miles: Your first month dose with basement protection only is ~130 rem. Survivable, though one might experience acute radiation sickness. Your added shelter in the basement might drop it below the threshold for ARS. It's hard to say because it's hard to know what the overhead component of the dose would be since you don't have shielding overhead so you take more rads from any fallout on the roof.

@100 miles: Your first month dose with basement protection is only ~8 rem. You probably wouldn't even show blood changes at that level (requires ~25 rem).

@1000 miles the fallout is almost negligible. Wouldn't even be 1 R/hr initial.

Shelter time @100 miles, try to spend the first 48 hours in the shelter. Then you can probably go out into the basement. Probably back into the house. Assuming it's not a collapse event, fallout reports and recommendations will be distributed via NOAA weather radio and other media sources.

Data below is for a 150kt burst with protection of a basement:
Code:
HotSpot Version 3.0.3 Nuclear Explosion
Oct 19, 2017 03:53 PM


Nuclear Explosion : 30.0 kT Surface Burst

Personnel exposed to a nuclear explosion may be killed or suffer injuries
of various types.  Casualties are primarily caused by blast, thermal
radiation, and ionizing radiation.  The distribution and severity of these
injuries depends on device yield, height of burst, atmospheric conditions,
body orientation, protection afforded by shelter, and the general nature
of the terrain.

The energy of a nuclear explosion is partitioned as follows,

50% Blast and ground shock
35% Thermal Radiation (Effective partition = 18% for surface burst)
15% Ionizing Radiation
   5%   Prompt  (first minute)
   10%  Delayed (minutes to years)

The 30.0 kT nuclear explosion produces a fireball of incandescent
gas and vapor. Initially, the fireball is many times more brilliant
than the sun at noon, but quickly decreases in brightness and continues to
expand. In about 1 second, the fireball will have reached its maximum diameter
of about 680 meters. After 1 minute, the fireball will have cooled
sufficiently so that it no longer glows.


BLAST

Blast casualties may occur due to the direct action of the pressure wave,
impact of missiles and fragments, and whole body translation and impact.
The destructiveness of the blast is a function of its peak overpressure
and duration of the positive pressure wave (or impulse). The 30.0 kT explosion
will produce in excess of the blast required to produce 100% Lethality
out to a distance of 0.38 km (0.23 miles)  Injuries associated with shattered
glass windows can occur out to a distance of  5.90 km (3.66 miles)

THERMAL RADIATION

Burn casualties may result from the absorption of thermal radiation energy
by the skin, heating or ignition of clothing, and fires started by the
thermal pulse or as side effects of the air blast or the ground shock.
Exposed eyes are at risk of permanent retinal burns and flash blindness out
to relatively large distances (especially at night when the diameter of the
pupil is maximum). Under daytime conditions,the 30.0 kT  explosion 
could produce temporary flash blindness from scattered light out to a
distance of  24 km (15 miles). Individuals who directly view the initial
fireball could experience retinal burns out to a distance of 27 km (16 miles). 
Unprotected individuals could receive in excess of the thermal radiation dose
required for third degree burns, out to a distance of 2.3 km (1.4 miles).


IONIZING RADIATION

Radiation casualties may be caused by prompt nuclear radiation or by
radioactive fallout. Prompt ionizing radiation consists of x rays, gamma
rays, and neutrons produced in the first minute following the nuclear
explosion. Unprotected individuals could receive in excess of the prompt
ionizing radiation dose required for 50% lethality (within weeks),
out to a distance of  1.6 km (0.99 miles)

The delayed ionizing radiation is produced by fission products and
neutron-induced radionuclides in surrounding materials (soil, air,
structures, nuclear device debris). These radioactive products will be
dispersed downwind with the fireball/debris cloud. As the cloud
travels downwind, the radioactive material that has fallen and settled
on the ground creates a footprint of deposited material (fallout).

The exposure to the fallout is the dominant source of radiation exposure
for locations beyond the prompt effects of the nuclear detonation. The dose
received depends upon the time an individual remains in the contaminated area.
Unprotected individuals remaining in the contamination zone for the first 
hour following the nuclear explosion could receive in excess of the fallout
dose required for 50% lethality (within weeks), out to a distance of
about  16 km (10 miles). The idealized maximum width of the fallout footprint
(actual width could be larger or smaller) is about 1.0 km (0.6 miles).
For individuals remaining in the contamination for the first 24 hours, the
downwind extent of the 50% lethality contour increases to approximately
46 km (28 miles). The 50% lethality contour width increases to about
to about 3.0 km (1.9 miles).


ELECTROMAGNETIC PULSE (EMP)

The EMP range for the 30.0 kT detonation is approximately 5 km (3 miles).
This range is the outer extent that any EMP effects are expected to occur.
Not all equipment within the EMP-effects circle will fail. The amount
of failure will increase the closer to ground zero the equipment is located,
the larger the equipment's effective receptor antenna, and the equipment's
sensitivity to EMP effects. Solid state devices are more sensitive than
vacuum tube devices. Least affected by EMP are electro-mechanical
devices such as electric motors, lamps, heaters, etc. Cell phones and handheld
radios have relatively small antennas and if they are not connected to 
electrical power supplies during the EMP pulse, will probably not be
affected by the EMP.

The effects of EMP occur at the instant of the nuclear detonation and ends
within a few seconds. Any equipment that will be damaged by EMP will
be damaged within those seconds. Electronic equipment entering the area
after the detonation will function normally as long as they do not rely on
previously damaged equipment, e.g., repeaters, power supplies, etc.

Jarry, thanks.

You gave an estimate of 50 r/hr and 10r/hr. Is that considered dangerous? Safe-ish? Somewhere in between?

When I try to look it up everything is in mSv.

How do I convert r/hour to mSv?

For Gamma 1 R = 1 rem = 1 rad

EDIT: You will sometimes see centigray as a unit (cGy), this is numerically the same as rad so 1 cGy = 1 rad. Like you, I'm stubborn about switching over to the SI measurements (Sv, Gy).

10 mSv = 1 rem so 10 rem is 100 mSv

If you want a handy calculator to go back and forth, go here: http://www.radprocalculator.com/Conversion.aspx
and choose dose equivalent.

Is 50 r/hr dangerous? That really depends on the situation and when you obtained that measurement. If your peak (usually T+1 hour) is 50 r/hr... it's dangerous, but survivable. You'll probably end up with a 1 month dose of ~160 rem. If measured after 2 days, outside is 50 r/hr... that's extremely dangerous because it means the original dose-rate was 5000 r/hr and it's going to be 50 r/hr for a much longer period of time.

For total dosage... in a short period of time here's a handy chart...



The faster you arrive at a dose, the more likely you are to suffer those effects. For example, you'll see that the LD50 is right around 425 rem. If you hit that dose in a matter of minutes to hours... you' have a 50/50 shot at survival. If You reach say, 125, then over the course of the next couple of weeks to a month hit 425... you have a better shot at surviving because your body has time to repair the damage.

O.K. - By the numbers

1 - The DPRK doesn't have a weaponized nuclear weapon(s)

2 - The DPRK doesn't have a ballistic missile capable of carrying a nuclear weapon.

3 - The large DPRK rockets have only managed to launch two small satellites into orbit, after many failures. These rockets cannot carry a nuclear warhead.

4 - STOP Drinking the Globalist Kool Aide. A nuclear war started by the DPRK is less likely than an insurrection lead by "My Little Pony".

The best protection from lies is to ask yourself, who benefits and why. Always questions everything you are told and think for yourself.

The people who run the DPRK are bad people, however they are not a direct threat to the USA. Didn't we learn anything starting with the Yellow Journalism of the Spanish American War, The Zimmerman Note and going through until at least the 2nd Iraq War???

THINK THINK THINK and Reason. It's that SIMPLE.

Then all the same questions for a bomb detonated in the air.

Assuming the best shelter we have is a brick room(with wooden roof) in the center of a cement basement. If we are 100 miles from the nearest explosion is that adequate protection? If so how long do we have to stay in there before moving the larger part of the basement?

I realize some of these questions may be stupid but do your best to help me understand.

This is not a discussion on the capabilities of North Korea, nor is it a debate on Globalism vs Isolationism. The OP asked a reasonable question and deserves a reasonable answer without a bunch of unnecessary flak.

If we strike North Korea China and Russia will probably declare war on us and then the US economy would collapse hence starting doomsday.

Which definition of doomsday?

Just curious.

A high ranking defector explained what he thought Kim was doing.

Basically, if he can get the US military out of SK by threats or whatever he thinks American businesses will pull out also. He thinks that if the US businesses pull out then the SK economy will crash and that will make them vulnerable. That is what the high ranking defector thinks.

Of course Americans do not think that way. Even if the US military would leave- which I doubt as they regard Kim's words as bragging, empty threats- the businesses would not leave. If necessary they would offer the people higher pay to convince them to stay but the businesses would not leave as long as there was a profit to be made.

Also, since the last soldier to escape was underweight and full of parasites, even if SK were to become unstable, the NK military is not in shape to take advantage of it.

Of course, Kim might just be lying to the high ranking people around him, just as he is lying to the NK people

Here is the info for a 150kt ground burst, the one above in my post from October is actually for 30kt. My narrative text was still correct. Shelter is assumed to be a basement (PF 10). You can pretty much figure out any other sheltering by multiplying the total doses by 10 to get the unsheltered dose then divide that by the protection factor. A frame house or building is usually a PF of 2.

Code:
HotSpot Version 3.0.3 Nuclear Explosion
Mar 05, 2018 12:24 PM


Nuclear Explosion : 150.0 kT Surface Burst

Personnel exposed to a nuclear explosion may be killed or suffer injuries
of various types.  Casualties are primarily caused by blast, thermal
radiation, and ionizing radiation.  The distribution and severity of these
injuries depends on device yield, height of burst, atmospheric conditions,
body orientation, protection afforded by shelter, and the general nature
of the terrain.

The energy of a nuclear explosion is partitioned as follows,

50% Blast and ground shock
35% Thermal Radiation (Effective partition = 18% for surface burst)
15% Ionizing Radiation
   5%   Prompt  (first minute)
   10%  Delayed (minutes to years)

The 150.0 kT nuclear explosion produces a fireball of incandescent
gas and vapor. Initially, the fireball is many times more brilliant
than the sun at noon, but quickly decreases in brightness and continues to
expand. In about 1 second, the fireball will have reached its maximum diameter
of about 1300 meters. After 1 minute, the fireball will have cooled
sufficiently so that it no longer glows.


BLAST

Blast casualties may occur due to the direct action of the pressure wave,
impact of missiles and fragments, and whole body translation and impact.
The destructiveness of the blast is a function of its peak overpressure
and duration of the positive pressure wave (or impulse). The 150.0 kT explosion
will produce in excess of the blast required to produce 100% Lethality
out to a distance of 0.64 km (0.40 miles)  Injuries associated with shattered
glass windows can occur out to a distance of  10.08 km (6.26 miles)

THERMAL RADIATION

Burn casualties may result from the absorption of thermal radiation energy
by the skin, heating or ignition of clothing, and fires started by the
thermal pulse or as side effects of the air blast or the ground shock.
Exposed eyes are at risk of permanent retinal burns and flash blindness out
to relatively large distances (especially at night when the diameter of the
pupil is maximum). Under daytime conditions,the 150.0 kT  explosion 
could produce temporary flash blindness from scattered light out to a
distance of  27 km (17 miles). Individuals who directly view the initial
fireball could experience retinal burns out to a distance of 31 km (19 miles). 
Unprotected individuals could receive in excess of the thermal radiation dose
required for third degree burns, out to a distance of 4.6 km (2.9 miles).


IONIZING RADIATION

Radiation casualties may be caused by prompt nuclear radiation or by
radioactive fallout. Prompt ionizing radiation consists of x rays, gamma
rays, and neutrons produced in the first minute following the nuclear
explosion. Unprotected individuals could receive in excess of the prompt
ionizing radiation dose required for 50% lethality (within weeks),
out to a distance of  2.0 km (1.25 miles)

The delayed ionizing radiation is produced by fission products and
neutron-induced radionuclides in surrounding materials (soil, air,
structures, nuclear device debris). These radioactive products will be
dispersed downwind with the fireball/debris cloud. As the cloud
travels downwind, the radioactive material that has fallen and settled
on the ground creates a footprint of deposited material (fallout).

The exposure to the fallout is the dominant source of radiation exposure
for locations beyond the prompt effects of the nuclear detonation. The dose
received depends upon the time an individual remains in the contaminated area.
Unprotected individuals remaining in the contamination zone for the first 
hour following the nuclear explosion could receive in excess of the fallout
dose required for 50% lethality (within weeks), out to a distance of
about  16 km (10 miles). The idealized maximum width of the fallout footprint
(actual width could be larger or smaller) is about 1.2 km (0.8 miles).
For individuals remaining in the contamination for the first 24 hours, the
downwind extent of the 50% lethality contour increases to approximately
42 km (26 miles). The 50% lethality contour width increases to about
to about 4.2 km (2.6 miles).


ELECTROMAGNETIC PULSE (EMP)

The EMP range for the 150.0 kT detonation is approximately 6 km (4 miles).
This range is the outer extent that any EMP effects are expected to occur.
Not all equipment within the EMP-effects circle will fail. The amount
of failure will increase the closer to ground zero the equipment is located,
the larger the equipment's effective receptor antenna, and the equipment's
sensitivity to EMP effects. Solid state devices are more sensitive than
vacuum tube devices. Least affected by EMP are electro-mechanical
devices such as electric motors, lamps, heaters, etc. Cell phones and handheld
radios have relatively small antennas and if they are not connected to 
electrical power supplies during the EMP pulse, will probably not be
affected by the EMP.

The effects of EMP occur at the instant of the nuclear detonation and ends
within a few seconds. Any equipment that will be damaged by EMP will
be damaged within those seconds. Electronic equipment entering the area
after the detonation will function normally as long as they do not rely on
previously damaged equipment, e.g., repeaters, power supplies, etc.
