Radkeeper Personal is a compact, lightweight, portable radiation detector (also known as a geiger counter, radiation meter or radioactivity meter) that detects X-rays and gamma rays. When radiation greater than 10 µSv/h (1 mR/h) is detected, the radiation detector simultaneously beeps and flashes. As radiation increases, the interval between warnings becomes shorter.
Radiation Detector Radkeeper Personal
Radiation detected X-rays and gamma rays Energy range 60 keV to 1.2 MeV Alarm signals (red LED light flash and beep)
(Average values relative to Cs-137)(Before emitting the first radiation beep, the device emits two short beeps to notify the user that the device is receiving an external signal.)
Silence: Radiation below 10 µSv/h
1 beep/min: 10 µSv/h
2 beeps/min: 20 µSv/h
3 beeps/min: 30 µSv/h
20 beeps/min: 200 µSv/h
Continuous alarm: > 200 µSv/hOperating mode Continuous operation Power supply 2 x 1.5 V button cells (SR44W) Battery life More than 6 months (continuous operation in absence of radiation) Operating temperature -10 °C to +40 °C Other functions Battery-test button
Signal emitted when battery is low (every hour over a 48-hour period)Dimensions 55 x 47 x 14 mm (without clip)
