A radiation detector comprises an extension shaped to be comfortably positioned in an outer ear area for obtaining temperature indications without discomfort to the subject. The extension increases non-linearly in diameter along a portion of its distal end forming a rounded distal tip. The extension is positioned in an ear canal such that the rounded tip is disposed at the opening to the ear canal. An infrared radiation sensor is positioned in the detector for receiving radiation emitted from the ear canal. An electronics unit converts the received radiation to a temperature indication.
