Skydose - Bertin Instruments

    Skydose dosimetry system for team operating in high exposure areas


    SkyDose is an operational dosimetry system designed for real-time monitoring of doses absorbed by a response team working in high-exposure areas.

    SkyDose teledosimeter system is designed to monitor in real-time the doses of a team operating on an area with high exposure. This system aims to improve intervention conditions and decrease the risks and exposure, in accordance with the ALARA principle.

    Only few minutes are needed to deploy the SkyDose system to a 8 people team on-the-field and follow-up thanks to industrial terminal type monitoring modules. The whole team can be managed from a monitoring PDA.
    Several teams can operate with Skydose at the same time. New systems can be easily and quickly deployed inside as well as outside of the facilities, without any specific training (automatic network synchronisation).

    Compliant with the use in nuclear facilities

    • Skydose complies with the IEC 61526 standard for measurement of personal dose equivalents

    Low maintenance costs

    • The Saphydose units used in Skydose system have a very long battery autonomy: more than 4 years with 2 AA batteries

    Adapted to all situations

    • Skydose can be installed in only few minutes. A whole system can be safely stored in a convenient aluminium case


    • It provides a real-time, remote and simultaneous monitoring of the dosimeters, so the team can react immediately in case of emergency

    A skydose system consists in 1 or several teams including 1 supevisor terminal monitoring 1 to 8 teledosimeters, and using a 2,4 GHz zigBee network. The mesh-structure network, flexible but sturdy, can reliably cover a whole building (such as a nuclear facility) by using dedicated routers.

    The teledosimeter unit is a radio version of the well-known Saphydose Gamma i, using the same reliable dual silicon diode for measuring X and Gamma rays, and having a measurement range of dose equivalent from 1 µSv to 9 999.9 mSv.

    It has a robust aluminium housing, tested at 10 shocks per side onto steel and 10 cm height of drop. It has also a very high immunity against electronic interference, with a 30A/m at 50Hz magentic fiels immunity.
