Time build-up properties of a recently developed radiophotoluminscence (RPL) glass made of silver-activated P2O5-Al2O3-Na2O-Ag2O, named "SAPANS" herewith, were examined using Cs-137 source gamma-rays. It was observed that the RPL intensities of SAPANS continuously increased at room temperature and did not reach a stable state even at six months after irradiation. For obtaining stable RPL values corresponding to dose levels, preheating at 160 degrees C for 1 h was judged to be the most suitable. The good weathering resistance of SAPANS was confirmed in a 63-days outdoor weathering test in the summer season; its physical and dosimetric properties were well maintained after the long exposure to the harsh environment. According to these findings, it is expected that SAPANS will be effectively applied to long-term radiation monitoring at various types of working/living places including outdoor fields.
