“Pero”, Wearable Pen-like Detector for Detection and Identification of Radioactive Contamination of Skin Wounds in Nuclear Medicine

In collaboration with Czech National Radiation Protection Institute (SÚRO), Crytur has developed a pen-like wearable device for detection and identification of radioactive contamination on skin wounds in nuclear medicine. This detector is based on a Crytur-grown YAP:Ce scintillator, which combines excellent energy proportionality and resolution with high detection efficiency to enable detection [1],[2],[3], localization and identification of the low energy gamma-ray emission from actinides used in nuclear medicine. Two prototypes have been built and tested by acquiring and analyzing the spectrum emitted by a pair of ²¹⁰ Pb and ²⁴¹ Am sources where the 46.5 keV and 59.6 keV lines can be clearly separated and identified. The detector construction and evaluation for the nuclear medicine purposes is discussed below.
