Finding effect far from lines

Sirs,

In your conclusion you wrote: "but it is nevertheless surprising to
find the effect extending so far from the lines."

But is it surprising? If the effect exists at all and if children
live near the lines, it will happen that they play or walk under or close
to them or visit neighbor houses closer to under the the lines. So one
might expect an partial effect related somehow to the partial time they
spend in the "effected" zone.
