Gamma Sapiens™ - Intellectual gamma radiation detector

About Gamma Sapiens™

The Gamma Sapiens intellectual gamma radiation detector is designed to measure radiation level and accumulated dose in everyday life.

Gamma Sapiens continuously transfers measurement results to the iPhone or iPad via Bluetooth channel in real time. With the help of GS Ecotest application this information is processed, displayed in a user-friendly way and stored in a special database.





Purpose of use:

  • measurement of gamma radiation dose rate (ambient dose equivalent rate)
  • measurement of gamma radiation accumulated dose (ambient dose equivalent)
  • transfer of measured values to the iPhone or iPad via Bluetooth


  • High dynamics and reliability of measurement results
  • Built-in Geiger-Muller counter of high sensitivity (it takes just 10-15 s to quickly evaluate normal radiation background level)
  • Communication with iPhone or iPad via Bluetooth
  • Transfer of dosimetric information to iPhone or iPad in real time
  • LED-based alarm of connection with iPhone or iPad
  • LED-based alarm of the battery discharge
  • Wide operating temperature range – from -18 °С to +50 °С (0°F to 122°F)
  • Ingress protection rating – ІР30
  • Power supply – two ААА batteries

Delivery kit:

  • “Gamma Sapiens” intellectual gamma radiation detector;
  • leather case;
  • operating manual;
  • ААА batteries – 2 pcs;
  • packing box.

GS Ecotest application provides:

  • information about the radiation level and accumulated dose which is transferred from Gamma Sapiens detector to the iPhone or iPad via Bluetooth in real time
  • display of measurement results in one of 4 different graphic representations
  • representation of collected data on a map with GPS coordinates
  • setting up one or more dose and dose rate threshold levels. When the threshold level is exceeded, light, audio, and vibration alarms will be actuated
  • data storage in a relational database
  • view of stored data in a database within a certain period of time
  • possibility to share measurement results via Facebook and Twitter
  • operation of the detector from the iPhone or iPad
  • making and receiving calls, sending and receiving messages, starting and using other applications, etc., without interrupting the process of measurement and loss of data
