Purpose and goal
The goal of the project was to develop two instruments for measuring radioactive radiation. The instruments must be based on microelectronics and fill gaps where no current equipment meets the requirements for accuracy, usability or economy. The project has fulfilled its goals through the development of a radon dosimeter and a handheld gamma instrument for the identification of radioactivity in construction materials.
Expected results and effects
A prototype for the radondosimeter has been developed and is under test. A patent application for the method is under preparation. The equipment will be commercialized by project participants. The developed prototype meets the requirements for sensitivity and power consumption. Furthermore, the principle of a simple handheld gamma instrument has been verified. The solution is based on a scintillator crystal with a photodiode and pulse electronics. The unit can, through spectrum, identify different radioactive substances.
Planned approach and implementation
The project started with in-depth studies on market situation and competitive situation, regulations within the field of radiation protection, and the need for radiation measurement in mines. These led to the development of a radon dosimeter and a simple handheld gamma instrument. Technical development has been carried out in close collaboration between Mid Sweden University, Gammadata and NOTE. LKAB has contributed with user views related to work in mines. SSM has contributed with support for regulations and application.
