Actually, the speed works like this. In your example, you take the damage and have to soak power 4 radiation immediately. Every month you have to save again, until the predescribed time limit occurs (of which there is none, which is why I said it doesn't matter, and you should theorhetically be able to get medical attention for it). It doesn't mean after 1 month of exposure you have to soak the damage. You have to soak immediately, then every month repeat until you are "cured."
Mild Radiation Poisoning's speed is Immediate.
...
An example is Influenza, with a speed of 12 hours (14). So after 12 hours of getting the pathogen, you have to make a test. Even if you reduce the power to 0, you have to make at least 14 tests before you are cured.
If we take it exactly as it's written, Radiation Poisoning's speed of Immediate (1 Month) can mean one of 2 things:
1) You save versus power immediately, and have to resave once a month until cured.
2) You save immediately and are irradiated for one month, after which you are cured.
However, the second option doesn't make sense because Sever Poisoning has a speed of Immediate (1 Day), which would mean you're irradiated longer when exposed to smaller amounts of radiation.
Alright, a closer reading of the five (!!) texts involved and your analysis above leads to the following analysis by me:
1.)
The format of the Speed formula for radiation means that the character does an immediate Radiation Resistance Test upon receiving radiation damage (ie. damage that is not dodged). If the damage is not reduced to 0, then the character must do another Test every (period) until it is reduced to 0. Since there is no third number, representing the number of Tests that must be done during which unresisted damage is added to the original damage (the 'disease' is getting worse), no such minimum exists. Therefore, radiation, unlike, say, cholera, doesn't have a time period during which it can peak if not resisted totally, and after which it abates. It's the same intensity from the start.
2.)
Radiation can be resisted totally, and if the damage is reduced to 0 on the first attempt (after some combination of Dodge and Resistance rolls), there is no further danger from the attack. In Arsenal, p. 168-169, the descriptions of the four levels of radiation damage from typical sources of radiation (not radiation elementals) describe the varying levels of ongoing damage that can come from exposure to sources of radiation, and not resisting totally on the first shot. The least severe form of exposure, 'mild', does not require decontamination along with curing/treating, whereas the middle two levels of contamination do. In other words, upon receiving 'moderate' to 'severe' radiation and not resisting it totally on the first shot, the character himself becomes radioactive and poisonous to himself. Ongoing effects accrue until decontamination and curing/treating. For all three of these levels of exposure, staying in the area of radiation will require repeated Resistance Tests. Sooner or later, one of them will not clear all the damage, and then lasting effects accrue. If one is going to experience radiation, it is good to have a high BOD and a protective suit.
Receiving damage from 'deadly' radiation, and not dodging/resisting it totally on the first shot will, as Neraph argues, kill you no matter what you do afterwards. If you stand there in the presence of the radiation, sooner or later you will fail to resist at least one DV of radiation damage, and then you are in the 'walking ghost phase'.
3.)
There is no clear direction in the text as to how to translate the radiation damage from Nuclear Spirits into the four categories of radiation damage in Arsenal. If damage from the attack of one such spirit is resisted fully, then there is no issue, as in all texts radiation damage does nothing to you if it is resisted fully on the first Test. The difficulty arises if some damage is taken. One must determine what level of the four levels of radiation poisoning the character has experienced.
Neraph argues that even a F1 spirit will poison a character with radiation right away even if it's attack is resisted, and there is no saving the character, as the radiation will continue to accrue. This is not true. The GM will have to determine how much radiation the character received from a successful attack by the spirit, based on things like how much damage was unresisted, how the attack was conducted (ranged or melee), the local environment (has the spirit irradiated the room?) and perhaps other factors. The Power ratings of the four levels of radiation poisoning are of limited help, as they don't differ as widely as one could hope, but they may provide a range of DV's to consider.
For example, if a F1 nuclear spirit hits for an unresisted 1 DV of damage, is it reasonable to treat it as even a mild radiation poisoning, as that has a Power of 4? Given the +4 DV for Energy Aura (radiation) it is possible such a spirit could do enough unresisted damage in melee to make the exposure moderate or even severe. Raising the DV up to 8 would be difficult, as the F1 spirit doesn't have all that many dice to attack with, and should most often be simply dodged.
As an aside, it should be noted that the +4 DV of Energy Aura only applies to the spirit's own attack. The damage the Energy Aura afflicts on an opponent if he hits in melee is equal to the Force of the spirit.
4.)
The exact nature of 'cured or treated' is also not clear. Does the Heal spell remove the effects of radiation? It heals damage, but doesn't remove pathogens, so probably not. The Decontamination spell seems to be the way to go if one intends to take on radiation. Note that the spell description (Digital Grimoire, p. 17) shows the spell adding dice to Radiation Resistance Tests, so it would appear from -this- text, the most recent one of all,
Neraph, that successfully reducing the Power of the radiation exposure to 0 fulfills the decontamination requirement for the lower levels of exposure.

I do not see nuclear spirits as automatic death sentences to a PC. Radiation is a special and particularly nasty form of damage, and needs to be treated with great care, but it is not the gamebreaking 'Destructor' that
Neraph fears.
Now, a F12 nuclear spirit.....
