|
Objective: |
Objective is to determine threshold levels of 94 GHz
millimeter wave exposure required to produce varying degrees of
thermal injury. Results from this study will be used to further define
safe exposure limits for the Active Denial System (ADS).
|
|
Approach: |
Recent developments in electromagnetic technology have
resulted in the design and manufacture of radio frequency radiation (RFR)
sources capable of generating frequencies in the millimeter wave (MMW)
length range (30-300 GHz). The depth of penetration of RFR at 94-GHz
has been calculated to be approximately 0.3 mm. Yucatan minipigs are a
well-established model for human skin and therefore will be used in
this study. Each pig will be exposed to 3 power densities at 3
durations for a total of 9 MMW exposures. A sham exposure will also be
done for each pig. Following exposure, animals will be allowed to
recover in their home pen. Trained veterinary personnel will visually
inspect animals at least twice a day. Five days after exposure each
pig will be euthanized at which time the irradiated skin and
superficial muscle will be excised and fixed in 10% neutral buffered
formalin for later histological examination by a veterinary
pathologist. |

Rats, mice, birds, amphibians and other animals have
been excluded from coverage by the Animal Welfare Act. Therefore research
facility reports do not include these animals. As a result of this
situation, a blank report, or one with few animals listed, does not mean
that a facility has not performed experiments on non-reportable animals. A
blank form does mean that the facility in question has not used covered
animals (primates, dogs, cats, rabbits, guinea pigs, hamsters, pigs,
sheep, goats, etc.). Rats and mice alone are believed to comprise over 90%
of the animals used in experimentation. Therefore the majority of animals
used at research facilities are not even counted.
