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.

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.
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:

HotSpot Version 3.0.3 Nuclear Explosion

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.
