Two scientists at Bell LabsArno Penzias and Robert Wilsonwere also building a horn to search for microwaves. Microwave radiation is also used to send telephone communications dry plywood and cure rubber. Microwaves Electromagnetic Spectrum There are many uses of radiation in medicine. . Microwave radiation is used in electron paramagnetic resonance EPR or ESR spectroscopy typically in the X-band region 9 GHz in conjunction typically with magnetic fields of 03 T. In the clinical setting this radiation is used for diagnostic processes and ironically enough the treatment of certain types of cancer. Microwaves can penetrate clouds of smoke but are scattered by water droplets so they are used for mapping meteorologic disturbances and in weather forecasting. Microwaves are used for cooking weather mapping radar and satellite communications as well as cellular phones over-the-air television signals GPS navigation and long-range t...
