    Gamma Sapiens is designed to measure radiation levels and doses.

    With the help of the GS Ecotest application, the information is processed, displayed in a user-friendly form on the Android smartphone or tablet, and stored in a special database for further viewing.

    Radiation is measured in real-time, it does not affect the use of a smartphone or tablet for its intended purpose. Gamma Sapiens will report a dangerous level of radiation with an audible signal and vibration. The device is self-powered, so it doesn’t use a smartphone or tablet battery.

    Gamma Sapiens designed exactly for your needs if you:

    • want to be sure of your radiation safety,
    • take care of your family,
    • are aware of possible radiation risks,
    • have a healthy diet,
    • own real estate or have projects under construction,
    • prefer active leisure time (tourism, hunting, fishing, skiing, etc.),
    • like travelling,
    • use cash,
    • want to choose a useful and original gift for the loved ones,
    • are an innovator who uses modern technologies,
    • are an active person interested in creating a contamination map of your area.

    Purpose of Use

    • Measurement of ambient dose equivalent rate (DER) of gamma radiation

    • Measurement of ambient dose equivalent (DE) of gamma radiation

    • Transfer of measured values to the Android smartphone/tablet via Bluetooth
