The aim of the work is development of a personal portable dosimeter of effective dose with the RFID data channel without built-in power supply source. Such personal dosimeters are in demand for long-term monitoring of the effective dose of ionizing radiation received by personnel when working with potentially hazardous radiation objects. The proposed X-ray detector has a novelty design with a Gafchromic EBT3 radiochromic film-based sensor element changing its transparency when exposed to ionizing radiation. The dosimeter circuit diagram has been developed and implemented. The dosimeter includes a microcontroller device estimating changes in the effective dose by determination of a degree of the sensor element varying transparency. The specific feature of the device is that it has no built-in power supply source. The dosimeter is supplied with radio frequency data transmission system. The active operating mode of the dosimeter is realized solely at the moments of data reading by external RF devices. The sensitivity of the developed device is expected to be at 0.034% / mGy, the lower dose limit of sensitivity is 1 mGy. The error of dose measuring by this method does not exceed 0.25 mGy.
