http://www.w3.org/ns/prov#value | - Because of the high frequency/short wavelength nature of microwaves, microwave radiation can penetrate optically thick smoke and water vapor, as molecules suspended in the air such as oxygen, water vapor, dust, and smoke do not attenuate the microwave radiation emanating from an object, whether the source of the radiation is a thermal incident such as a fire or an intruder or other object.
