초록
국내에서 생산된 농산물의 방사선 조사유무를 확인하기 위하여 TL을 측정하였다. 모든 시료의 first glow curve는 조사선량이 증가할수록 TL intensity도 증가하는 경향을 보여 주었다. 당근, 생강, 감자, 고구마의 상관계수는 0.8522, 0.9968, 0.9612, 0.9071의 높은 값을 나타내었으며, first glow curve의 최대발광온도점은
A study was carried out to establish the detection method of irradiated agricultural products cultivated in Korea by Thermoluminscece(TL). Samples were irradiated using Co-60 gamma rays at various doses(0.05, 0.1, 0.2, 0.3 and 0.5 kGy). After irradiation, separated minerals of the samples measured by TL. TL intensity increased with increasing doses and the irradiated samples were higher than the non-irradiated samples. TL first and second glow curves showed maximum TL temperature point at
