Here is something that has bugged me for quiet a while.
Sometimes, when I have a very low rad count, around 2-5 maybe, I seek out my Settler Doc, who runs the clinic (tier 4) and ask them to remove my rads. I fork out 40 caps for the service. Yet, my rads are never fully gone.
My health bar still stays visible. I drink a bottle of water to fill up the HP meter, yet, it seems that there is always a sliver of rads left. Maybe my settlers are not fully qualified to "play doctor" and can only remove ONE rad at a time or what? Anyone know how much rads this service should actually remove? Or is this a bug? (playing on PC btw.)
I actually never go back and just end up using a Rad Away anyway. Maybe next time I see how many "sessions" it will take to fully remove 5 rads.
Need to also test this with an "actual" doc, like the traveling one or the one in DC.
