How come if you're in one hallway of a building you're good, and a couple hallways down the right you're instantly exposed to a lethal dosis of radiation? Shouldn't it be a bit more gradual?

I would think it would depend on the construction materials of the building. Certain materials block radiation more than others."A society grows great when old men plant trees, the shade of which they know they will never sit in. Good people do things for other people. That's it, the end." -- Penelope Wilton in Ricky Gervais's After Life

Well we don't really know that they were ok before they found the geiger counter. Given how crazy that geiger counter was going I would think that everyone in the building and even the people outside where Telford was would all have been exposed to dangerously high amounts of radiation.
Of course that's not how it will turn out, Greer/Covel and Wray/Michaels will be the only 2 people exposed to the radiation. Just like in SG1 Meridian all the Langaran scientists die from radiation poisoning, Daniel defuses the bomb and dies a day or two later from extreme radiation poisoning yet Jonas who was about 5 feet away from Daniel goes on to live happily ever after.

various forms of radiations have highly varying degrees of penetration. plus that the air itself could have become radioactive.

Or it could be the contaminated dust, as Tajis mentioned. A radiation source inside the body is highly dangerous.sigpic

For distance, radiation does not act like radio waves, but it is more like line of sight (only some time you can get radiation to reflect off surfaces, but this is a minor effect). Therefore, as you get to be more in the line of sight with respect to materials that can shield the radiation, the radiation will spike.
Now, with all that said, I know how to read a Geiger counter and those levels WERE NOT lethal for the amount of TIME they were exposed, it was just added for dramatic effect. I also don't understand how the levels did not change all that significantly from the hallway till when you were standing right next to the device.
All in all, this episode was not very factual about radiation and as a nuclear engineer, it pisses me off to always see the public be so misinformed about radiation and dosage.

Originally posted by DigiFluid View PostYeah it really depends. Certain types of radiation are blocked by something as simple and thin as paper, others will only be slowed down by a wall of lead. It really depends on the kind of radiation that's being....radiated.
Beta - Blocked by all of your skin together (dangerous if consumed)
Gamma/Neutron - Pretty much go through anything. 2" of lead will reduce gamma by 90% (this is called tenthing factor). Gamma is reduced by dense materials like lead and tungsten, neutrons are reduced by materials high in hydrogen (such as water and certain types of plastics. Lead can also work).

He was further than that by at least double. Also: re-read the posts above about distance to decay ratios."A society grows great when old men plant trees, the shade of which they know they will never sit in.
