| 内容記述 | A new thyroid monitor using multiple high energy resolution Gd3(Al,Ga)5O12(Ce) (HR-GAGG) detectors with each crystal size of one cubic centimeter has been developed, in particular with an intention of measuring small children (including infants) for their internal thyroid exposure from radioiodine following a nuclear accident. The small-sized HR-GAGG detectors allowed to be placed around the human neck at the close distance to increase the geometrical efficiency for 131I localized in the thyroid. An arrangement of eight HR-GAGG detectors surrounding the neck was tested using age-specific phantoms in each of which a thyroid-shaped container filled with standard 131I solution was installed, demonstrating that the minimum detectable activity (MDA) of the new monitor reached 20–30 Bq with a counting time of 180 sec, which was about 10 times lower than that of a conventional NaI(Tl) survey meter (with a crystal size of 1 inch in diameter and 1 inch in thickness) commonly used for measuring air dose rates. | |||||
