I am trying to set the radiation at the launch site, more precisely at the Rocked factory. When I moved the radiation reach to 10 I found out that the radiation center is not located inside the building. It is located in front of the building at the center of the wall contained compound. So if I want to set radiation high in and on the building (in order to avoid Roof campers) the radiation in front of the building will need to be amplified killing anyone who approaches the building from the front side.
Any Idea on how to relocate the radiation center?

Thank you in advance
