Photostimulated luminescence (PSL), thermoluminescence (TL), and electron spin resonance (ESR) analyses were performed to identify ${gamma}$-irradiated (0, 1,2, and 3 kGy) fresh mushrooms (oyster, king oyster, and shiitake mushrooms) during storage at $5^{circ}C$. PSL analysis gave negative results [<700 photon counts (PCs)] for the nonirradiated and intermediate (700-5,000 PCs) or positive results (>5,000 PCs) for the irradiated samples. The shape, intensity, and occurrence of TL glow curve in a typical temperature range (150-$250^{circ}C$) along with TL ratio ($TL_1/TL_2$) provided sufficient information to confirm the irradiation history of samples. Storage resulted in a negligible fading effect on PSL and TL characteristics. X-ray diffraction analysis showed the abundance of feldspar and quartz minerals in the separated dust from mushrooms. In detailed ESR analysis employing different sample pre-treatments, all samples were silent for radiation-specific ESR signals giving only a central signal (g=2.005) that showed an increase in intensity upon irradiation.
