By use of a CdTe crystal coupled to newly designed, low power electronics, we have developed a new personal radiation chirper that is superior to existing instruments. The device emits audible chirps or beeps at a rate proportional to the photon radiation exposure to the wearer. The device is small (6.2 cm high by 3.2 cm wide by 1.7 cm thick) and of low mass (50 grams) and is made to be clipped to the shirt collar of the wearer. The instrument has long continuous-use battery life and is sensitive over a large photon energy and exposure rate span.
