May I know how close is the TNB building itself from your house?

What if the TNB sub station compound is seperated by a small lane, will it be better? How far away will it be acceptable for those who wants to play safe? What about the 2nd house from TNB, is that OK? I never really thought about TNB subs station as risky. All the while, I only hear about power grid lines which can cause cancer. Is the public perception of the TNB substation as bad as the power gridlines?

I think getting leukemia is from high tension power lines lah, not those substation.
