Dumb down the basics of what wouuld happen
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.

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

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.

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 nonpublic resources) for surface burst info. Quote:
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 neutroninduced 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 EMPeffects 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 electromechanical 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? Safeish? Somewhere in between? When I try to look it up everything is in mSv. How do I convert r/hour to mSv?

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 doserate 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. Quote:

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

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 neutroninduced 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 EMPeffects 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 electromechanical 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.
