5.2 Definition of the Environment
The uppermost level limit of the environment that can be exposed to radio
magnetic radiation is of two kinds: one is "controlled environment" and the other
is "uncontrolled environment " with less radiation.
Controlled Environment
l
Controlled environment refers to a certain location where the personnel who
enter the area are aware of the potential threat of exposing themselves to the
radio frequency radiation environment. Generally, the personnel enter such
areas for the profession requirements and they get acquainted with this danger
or they just pass by the areas where possible radiation exists. The magnetic
field level of the area is higher than that of "uncontrolled environment" but no
greater than that of "controlled environment" listed in the table.
Uncontrolled Environment
l
"Uncontrolled environment" refers to a certain location where the personnel who
enter the area are not aware of the potential threat of exposing themselve s to
the radio frequency radiation environment, and they cannot control the
environment where they are situated. This location may include living
