RF radiation exposure levels below 1Mw/cm^2 are permissible levels in accordance with
OET Bulletin 65, Edition 97-01.
The above graph depicts permissible levels at required safe distances from the isotropic radiator. The
incremental gain of the radiator can be increased in accordance with the distance of the human body
removed from the radiator by the corresponding distance in centimeters. As can be observed, the distances
are marginal but notice should be observed never the less.
