MTP 1(D), Vol. I
b. Instructions.
(1) Identify and attenuate potentially hazardous RF fields by physical controls wherever possible,
protective equipment, administrative actions, or a combination thereof.
(2) Limit RF field exposure of personnel to levels that do not exceed the PELs given in the following
figure.
(3) Define and control areas in which RF exposure of personnel could exceed the PEL. Ensure that
personnel are aware of potential RF exposures in their workplaces and duty assignments.
(4) Investigate, document, and present recurrences of RF overexposure.
(5) Use RF Hazard Warning Signs as shown in STANAG 1379 RAD, or the national standard to
warn personnel of hazardous areas.
(6) The following figure gives the Personnel Exposure Limit expressed as equivalent power density.
