Abstract
A simple and inexpensive photoacoustic radiation detector requiring no cell machining and minimal preparation is proposed. It consists of the front air chamber of a commercial electret microphone used as the transducer medium itself. The measured noise-equivalent power (NEP) at a modulation frequency of 40 Hz was found to be of the order of 5*10-7 W Hz-1/2 for both black-body and visible illumination.Keywords
