Default HF antenna and Power line ?

Hi,

With a friend we have to install a beam near a HV Power line (we ignore its
power) located 300 m from the QTH.

Has someone among you a chart or table listing the EM field and Electric
field of various HV power lines ?
I know that a HV power line (I don't know its power) displays e.g. an EF of
10 kV/m and an EM flux density of 10 microT.
and that the field decreases like 1/r^2 and that there is a epidemiological
risk from 2 miligauss.
I also know that the administation denies any construction in the 50m around
such HV line due to the risk for the health
But these are all data I have. Not enough to appreciate to risk of this
specific installation.

My questions are :
- Is there a risk that this HV power line disturbs DX QSOs in HF bands (and
QSO in VHF, but here I doubt much)
- What is the risk for the health at such a distance according to the
voltage ?

Thanks in advance
