Dose Alert Radiation Beeper – (Dose Rate)

In another low cost variation of Dose Alert, the radiation level is continuously indicated by short audio beeps and 4 LEDS which light up whenever the radiation dose rate exceeds four preset levels of 2 mR/h, 5 mR/h, 50mR/h & 100mR/h. When the highest dose rate level is exceeded, the beep becomes continuous. The Dose Alert beeper is a low cost, compact, pocket / key chain device for radiation warning.
