How long does it take to wear off (Fallout 3)?--Cc123 20:58, 21 April 2009 (UTC)


1 In-game hour. --[[User:Bar27262|Bar27262] 21:01, 21 April 2009 (EST)

Has there been any consideration to the fact that these might be Potassium Iodide pills? They were a pretty common ingredient to any fallout shelter during the cold war, and are still common among survivalists who are afraid of a nuclear war. They basically have the same effect as this med, so it could be a "commercialized" Potassium iodide pill in the Fallout world. The article seems to think they're a magical, medical marvel.

i doubt that they would be because Potassium Iodide pills only protect the user from a very specific type of radation and would be ineffective in the situations the player character finds themself in because the would likely be more than that very specific type of radationJhonteay 16:00, 16 June 2009 (UTC)

Actually, Atomic645 has a point. Chemically, yes, Rad-X could be iodine-based. That, and a terminal in L.O.B. Enterprises mentions that, among meat rations and personal geiger counters, iodine pills would be distributed to members of the sovreign L.O.B. Republic.

fair enough they could be iodine based but rad x seems fair superior to iodine pills which my chemistry/physics teacher told me that iodide pills are pretty useless unless under very specific circumstances,Iodide tablets they are more or less used to calm nevers were as rad x has an actual effect.so what im saying is they could contain iodine but thay are not iodide pillsJhonteay 16:16, 16 June 2009 (UTC)

Huh? Of course they'll be useless in a non-nuked world. Well... until the chemical makeup of Rad-X is confirmed, I guess anything goes. Nitpicker of the Wastes 16:19, 16 June 2009 (UTC)

The purpose of iodine pills is to saturate the thyroid gland with normal iodine, preventing it from absorbing any radioactive iodine. This helps prevent thyroid cancer. It has no effect on other radioisotopes (e.g. from fallout), nor does it protect against direct radiation. Since it's rare to encounter radioactive iodine alone (except, ironically, as chemotherapy for thyroid cancer), the actual usefulness of the pills is quite low. Rad-X is powered by magic.

Don't forget that radiation is nerfed in the Fallout universe, as it can't fucking give you cancer and people apparently only get tired when poisoned by radiation.So iodine pills would still be plausible.

But yeah, as far as we know it's magic, or shitty plot element. FalseBenefactor 13:38, April 6, 2010 (UTC)

Rad-X and low radiation areas?[]

So I have an ungodly amount of Rad-X on my person. I'm not sure what it is with this character that uses less chems, but I have well over 200 stimpacks and 60 Rad-X. I've been wondering if they have any usefullness in areas that only give you 1rad/sec. The number on the screen doesn't change when I pop a pill, but it seems that the rads do get slower, but it's hard to tell since the increase is so gradual. I just want to know if there's any point in popping one of my plentifull Rad-X pills in a situation where I am going to find myself in irriadiated water for an extended period of time. --98.180.4.125 20:48, October 10, 2009 (UTC)

Radiation Resistance can never make the PC completely immune to Radiation. Though, in theory, if your Radiation Resistance was at a ridiculous number (like 99.999999%) even the radiation at Vault 87 could be reduced to 1 rad/sec (though Radiation Resistance is capped at 85%, so this is impossible without mods). My point is that the minimum amount of rads the PC can receive is 1 rad/sec, so Rad-X is useless in areas already at 1 rad/sec. 68.192.9.90 22:25, November 1, 2009 (UTC)

Fallout 1 companions[]

Somebody help me out with this: Can you force-feed Rad-X to your followers in Fo1? Specifically, Dogmeat?

Locations, Locations[]

Shouldn't we list locations for Rad-X in Fallout 3 and Fallout: New Vegas, since 1 and 2 are covered?

No need, its everywhere in Fallout 3. And in New Vegas, there aren't many irradiated areas.

Vandalism?[]

"Rad-X is best used while playing in sperm." Er, what happened there? --Phoenix 06:00, November 21, 2011 (GMT)

Does Rad-X affect radiation from food?[]

It should be stated whether Rad-X will affect radiation gained from food. AbsentCollaborator (talk) 07:07, March 23, 2013 (UTC)
