Hi ShotgunNinja,
thanks for this essential mod. I even paused at the last game-update till you updatet to actuall version.
Now with this new anti-radiation-part you made my day.
Today I outfitted my minmus space station with this part.
Radiation went from 0,002 rad to 0,001 (with two parts).
Then I went to KSP and had the window of that space station open.
In background radiation went up to 0,002 again.
When I went back to the station it went again to 0,001.
This means: there seems to be a problem with that part if calculated in background.
Could you please look on your anti-radiation-part in background use again, thanks!
