The present paper reports the photoluminescence (PL) and thermoluminescence (TL) studies of natural limestone collected from Semaria mines of C.G.Basin in India. The sample was irradiated with Sr-90 beta source giving a dose of 10Gy and the heating rate used for TL measurements are 6.660 C/sec was described. The sample displayed good TL peaks at 1080 C and the corresponding activation energy (E) values are calculated. Photoluminescence emission spectrum peak at 390 nm is reported.
