The smallest nuclear wepaon ever fielded - W54 for "Davy Crockett"
recoiless launcher was 10 ton nominal yield (.01 kt). It would emit
lethal gamma radiation for radius of over 350 meters. No radiation
was detected at WTC site.

This one has repeatedly been shown and proven to be from the clean-up, months after September 11.

Yeah I noticed something alright, I noticed on the front of the beam, the slag is on the outward facing side which means if it was cut with a torch like you guys keep contending, then the welder must have been a frigging contortionist to crawl inside that box column and cut outward.
WTC Steel showing obvious torch marks. The torch was angled towards the lower part of the cut (not perpendicular to the column face), probably to keep the hot slag moving away from the operator. The thickness of the steel, combined with the angle of torch and the diagonal ("downhill") direction of the cut, makes for a cut that produces a lot of slag. Slag adhesion to such columns would be expected to vary with temperature, surface condition, and type of torch used. Note the apparent slag, circled in red, that's sitting on top of the loose debris. That could only get there after the collapse. What we don't see – on any WTC steel – is the deep vertical cutting and huge amounts of residue and slag that would be expected to come from the enormous amounts of thermite/thermate that some conspiracists claim was used. They would like us to believe that such an incendiary was used on this one sub-grade column. They are wrong.
Effects of a nuclear explosion
The energy released from a nuclear weapon comes in four primary categories:
Blast—40-60% of total energy
Thermal radiation—30-50% of total energy
Ionizing radiation—5% of total energy
Residual radiation (fallout)—5-10% of total energy
The amount of energy released in each form depends on the design of the weapon, and the environment in which it is detonated. The residual radiation of fallout is a delayed release of energy, while the other three forms of energy release are immediate.
A radioactive fireball tops the smoke column from a nuclear weapon test.The dominant effects of a nuclear weapon (the blast and thermal radiation) are the same physical damage mechanisms as conventional explosives. The primary difference is that nuclear weapons are capable of releasing much larger amounts of energy at once. Most of the damage caused by a nuclear weapon is not directly related to the nuclear process of energy release, but would be present for any explosion of the same magnitude.
The damage done by each of the three initial forms of energy release differs with the size of the weapon. Thermal radiation drops off the slowest with distance, so the larger the weapon the more important this effect becomes. Ionizing radiation is strongly absorbed by air, so it is only dangerous by itself for smaller weapons. Blast damage falls off more quickly than thermal radiation but more slowly than ionizing radiation.
When a nuclear weapon explodes, the bomb's material comes to an equilibrium temperature in about a microsecond. At this time about 75% of the energy is emitted as primary thermal radiation, mostly soft X-rays. Almost all of the rest of the energy is kinetic energy in rapidly-moving weapon debris. The interaction of the x-rays and debris with the surroundings determines how much energy is produced as blast and how much as light. In general, the denser the medium around the bomb, the more it will absorb, and the more powerful the shockwave will be.
When a nuclear detonation occurs in air near sea-level, most of the soft X-rays in the primary thermal radiation are absorbed within a few feet. Some energy is re-radiated in the ultraviolet, visible light and infrared, but most of the energy heats a spherical volume of air. This forms the fireball.
In a burst at high altitudes, where the air density is low, the soft X-rays travel long distances before they are absorbed. The energy is so diluted that the blast wave may be half as strong or less. The rest of the energy is dissipated as a more powerful thermal pulse.
I hope you understand there is evidence to suggest an emp here, aside from the tell tale loss of radio and cb signals at the moment before each collapse. If you have a basic understanding of an electromagnetic pulse, then you understand it primarily effects metals and electrical equipment, variances in strength and intensity, or damage, depends upon a number of factors such as range or angle to the blast, geographical or constructed shielding.
The high temperatures and energetic radiation produced by nuclear explosions also produce large amounts of ionized (electrically charged) matter which is present immediately after the explosion. Under the right conditions, intense currents and electromagnetic fields can be produced, generically called EMP (Electromagnetic Pulse), that are felt at long distances. Living organisms are impervious to these effects, but electrical and electronic equipment can be temporarily or permanently disabled by them. Ionized gases can also block short wavelength radio and radar signals (fireball blackout) for extended periods.

As for nuclear weapons - what does the time W54 was developed have to do with it?
Will still emitt lethal radiation for considerable distance
Why dont you do some real research.....?
As for car fires - cars were first set on fire by burning debris. Fires spread
from car to car - Ever see a vehicle fire in parking lot? Been there when
3-4 cars burning at once. Fire started in one and spread to others
