Idose personal dosimeter is independently designed and manufactured by Shanghai xinman Sensing Technology Co., Ltd. and is mainly used for staff in nuclear medicine or related work exposed to radioactivity. When the staff wear a dosimeter to work in the radioactive area, it can effectively and quickly monitor the radiation dose received by the body, so as to find out the excessive radiation dose in time, It is an important guarantee for the life safety of workers exposed to radioactive work. Idose personal dosimeter app can display measurement data wirelessly and synchronously in real time, and support users to view the changes of their radiation dose value and dose rate at any time, so as to change the passive radiation record into active management. Idose personal dosimeter provides basic data for low-dose radiation health research and is an important part of Sim-max intelligent radiation safety management platform. Users can connect idose app through Bluetooth to establish a lifelong traceable personal radiation dose health file. At the same time, combined with the global positioning system (GPS) of mobile terminal, accurate dose measurement of time, location and dose rate can be realized.
