So, the problem written in title.
No one door in mod can protect your home against radiation.
I think it's happen because 'door tile' ('tech block' who replacing space in door when you close it) dont have rad-resist. And if you want to build bunker you need to use vanilla doors maked from pistons and concrete bricks.
For example high-tech blast protect door on screenshot doesnt have any radiation resistance (im looking at this 'tech block'). I think its be a good thing if you make this doors more usable. Not for all doors of cource, because some doors named as fire-resistant and etc. But the blast-protected doors, or QE containment door looks like they can protect your home from radiation.
Sorry for grammaticus errors, english is not my main language.

will look into it

I fixed that a while ago in my fork. Will roll out soon.

Closing as it has been fixed
