Skydose - Bertin Instruments



    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 in 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 a few minutes are needed to deploy the Skydose system to an 8-person team in the field and follow them 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 the facilities, without any specific training (automatic network synchronization).

    Compliant with 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 the 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 minutes. A whole system can be safely stored in a convenient aluminum case


    • It provides 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 supervisor 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 aluminum housing, tested at 10 shocks per side onto steel and 10 cm height of drop. It also has a very high immunity against electronic interference, with a 30A/m at 50Hz magnetic fields immunity.


    • Multifunctional reader for Saphydose Gamma i operational dosimeter / teledosimeter


    • Dosimetry management software

    Easydose setting software and Saphyr Dosimeter reader

    Reasons to choose Skydose

    Easy and quick setting even by non-specialized staff

    Automatic network synchronization

    Suitable for indoor and outdoor use including reactor buildings

    Suitable for emergency situations (sturdy – high dose and dose rate range)

    Real-time hotspots detection to reduce the mission dose received by workers
