The radiation detector (50) includes a receiving antenna made up of at least two pieces of metal externally attached to the microwave antenna within the abdomen. The radiation detector (50) is adapted to receive errant microwave energy that resonates in the abdomen. A rectifier (54) is coupled between the two pieces of metal (52a, 52b), where the pieces of metal are strips, rings, patches, or other geometric combinations. The rectifier (54) is adapted to rectify at least a portion of the errant microwave energy. A filter is coupled to the rectifier and is adapted to convert the rectified microwave energy into a detection signal. An inflatable stop (30) is located on a distal end of the microwave antenna and the inflatable stop (30) is inflated when inserted within the abdomen. The inflated stop (30) prevents inadvertent removal of the microwave antenna.1/6 GENERATOR 1 114 T 50 71 2 17 18 FIG. 1
