@Zim y u no call me any other alias? (thinking of changing my name back)
@Azery, I suggest you guys put some hints of the story (or even character backstory) of the region, to the sidequests, just to give the audience an extra incentive.
Also, regarding radiation, since I took a Radio-protection (in physics) class, I know that the immediate effects of it are diminished several months after the nuclear outburst. Even the "cloud" has to settle somewhere. Avoiding to eat vegetables, dairy products and meat from the specific regions for 3-4 months and you should be ok. The reason is that U, Rd, Ra, and PU, all have a small time of "half-life" (not correct translation). At the same time, how deep the rays will enter (range) depends on simple Compton and Reyleigh effects. Therefore, after that time, it's basically safe to consume products from the regions in the blast radius (including all that the cloud has ended up on) and live a normal life. The various aftereffects of the radiation were of course no joke, with multiple people being affected into having cancer and/or deformities. However, now, in 3m-isle due to the radius and how small the cloud was, the average radiation input in each person is more or less about the equivalent of 1 x-ray. So, it's perfectly safe (given an x-ray (low dose, low LET) may increase your chance for cancer about... let's see... 0.0005%). Now we had multiple uninformed women who decided to stop their pregnancies due to fear, even if they had received much less than 100mSv (which is the minimum to even consider stopping it) which means about 10k people died for nothing as others thought that the radiation was much worse than it really was. Now, I do not know how the "medicine" those guys receive will work, since radiation effects cannot be stopped with casual meds with the exception of those who stop the creation of "free e-" in the cell, but that's something you can do with VitC as well, thanks to its anti-oxidization properties. *
As correctly mentioned above, most insects need a LD50/60>1000Gy as a lethal dose (while humans need 5Gy). I believe your ability would become much more complicated if you included the bugs, but it would make sense. Since it causes TOX instead of PSN, and has double the opportunities to do so, shouldn't you decrease the chance to 20%? You know, just to keep it non-broken.
