Abstract

Gamma radiation have dangerous effects and cannot be detected by the human body. Therefore, a detector that can detect the presence of a radiation source is needed, known as a radiation detector. Detector is a material that is sensitive to radiation. This study aims to make a gamma radiation dose detector using the principle of localized surface plasmon resonance (LSPR) silver nanoparticles and characterize it using a UV-Vis spectrophotometer. AgNO₃ solution was mixed with cobalt-60 radiation source Gammacell irradiator with small dose variations. PVA in this study acts as a capping for the formation of silver nanoparticles when irradiated. When the AgNO₃ solution mixed with PVA was irradiated with doses of 1Gy, 4Gy, 7Gy, 10Gy, 30Gy, 50Gy, 70Gy, 100Gy, 200Gy, 500Gy, and 1000Gy so that the color change from clear to yellowish with increasing doses, and the color change indicates that silver nanoparticles have been formed. The change in color from clear to yellowish is due to the occurrence of localized surface plasmon resonance (LSPR). The results of characterization of silver nanoparticles using a UV-Vis spectrophotometer showed that the maximum absorption of silver nanoparticles was between 410-446 nm to 0.5 M while at 1 M it was between 411-437 nm.
