How it works?
The GQ-500/GMC-500+ Geiger Counter installed Geiger tubes to detect radiation.
When the radiation pass through the Geiger tube, it triggers electrical pulses for the CPU to register
as count. The basic count rate unit is CPM(Count Per Minute). The CPM count rate indicates the
radiation level and it can be converted to a other traditional radiation units, such as uSv/h or mR/h.
After unit turned on for one minute, it will show the background radiation reading. The background
radiation reading (in CPM) indicates the nature radiation detected at that minute. This reading may
change from time to time and location to location. To get accurate reading, user may need to get an
average value over a longer time period.
The GM-500 built-in intelligent algorithm always select one of the most adequate sensors to
measure the target, so that to guarantee the accuracy of the measurement.
Caution
1. Avoid doing measurements when battery low.
2. Do not get the Geiger counter wet. Use sealed plastic bag to void wet.
2. Avoid doing measurements in direct sunlight.
3. Avoid directly contact the radioactive material. Use sealed plastic bag if needed.
4. Turn off the unit when not in use.
5. Keep it in a protective pouch after use.
6. When the unit not in use, store it in a dry place or box. This will avoid mechanical part be
oxidized, such as button or battery contacting points.

Background Safe Levels
Suggested background readings levels:
1. Safe level. Less than 50CPM or 0.325uSv/h. Means no worry at all.
2. Attention level. 51CPM – 99CPM. OR 0.326uSv/h – 0.65uSv/h . Means you need to find out
why .
3. Warning level. More than 100CPM or more than 0.65uSv/h. Means do not stay in this area for
long period.
