3-9. ARMY PROGRAM
a. Department of Defense Instruction 6055.11, Protection of DOD Personnel from
instruction is to limit personnel RF exposure to permissible exposure limits specified in
the Institute of Electrical and Electronic Engineers (IEEE)/American National Standards
Institute (ANSI) C95.1 "Standard for Safety Levels with Respect to Human Exposure to
Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz".
b. Memorandum, U.S. Army Health Professional Support Agency, SGPS-PSP,
30 October 1991, subject: Microwave Oven Radiation Control Program.
(1) This memorandum revokes the initial and periodic comprehensive survey
requirement for new or in-service microwave ovens. The visual inspections combined
with radio frequency leakage measurements were performed by trained 91S personnel.
Training to perform these surveys was provided to 91S personnel at the Academy of
Health Sciences. As a result of a review and evaluation of the entire Microwave Oven
Radiation Protection Program, comprehensive surveys of microwave ovens are no
longer required. Additional requirements to (1) maintain records of comprehensive
surveys, (2) maintain a comprehensive inventory of microwave ovens, and (3) post
(2) Comprehensive surveys shall be performed on microwave ovens offered
for resale to the public. Use USAEHA TG No. 153, April 1987, Guidelines for
Controlling Potential Health Hazards from Radio Frequency Radiation for guidance.
(3) Units that have qualified individuals and the necessary equipment are
encouraged to perform surveys of microwave ovens upon request. Units should not
purchase equipment to perform these surveys. Those without the capability to perform
requested surveys may request assistance from: Commander, USACHPPM, ATTN:
MCHB-TS-ORF, 5158 Blackhawk Road, Aberdeen Proving Ground, MD 21010-5403.
Section II. LASER RADIATION
Laser light differs from ordinary light in that it is much more intense, directional,
monochromatic, and coherent (that is, the same color and in phase). The light emitted
by an ordinary source--such as a candle or an incandescent lamp--consists of
uncoordinated waves of different length, that is, it is incoherent and more or less white.
The waves of laser light are coordinated in space and time and have nearly the same
length. This color purity and intensity of the laser light result from the fact that excited
atoms are stimulated to radiate excess energy cooperatively.
