“…The γ -or β-irradiations of different micas reveal the presence of a low temperature peak located at 160 • C (5). The dose responses of glow peaks of natural muscovite from Nigeria have a super-linear behaviour at low doses followed by linearity, and then become sub-linear at high doses (7). Comparing our results with the previously mentioned literature, it was shown that our mica sample possess similar properties.…”

“…The sensitivity of the blue band can be enhanced by providing the possibility of using muscovite in TL dosimeters. Thermoluminescnce of γ -irradiated muscovite samples from Nigeria has also been studied (7). The dose responses of the glow peaks had a super-linear behaviour at low doses followed by linearity, and then become sub-linear at high doses.…”

A thermoluminescence phenomenon has been observed in synthetic mica. The pristine sample glow curve provides the presence of TL glow peaks at 210, 260, 275, 300, 330 and 380 • C with trap depths of 0.11, 0.46, 0.82, 1.4, 0.61 and 0.54 eV, respectively. The thermal activation energies of these defects were estimated by using the initial rise method. Gamma and electron beam irradiations have induced completely different glow curves in mica, which reveal the presence of other low temperature traps in the range 54-195 • C. The TL growth curves reveal the possibility of using the investigated material in accident dosimetry.

“…Kristianpoller et al, 1988;Krbetschek et al, 1997;Soliman, 2003;Ige et al, 2006;Lakhwant et al, 2012) and (iii) reveals luminescence properties that can vary from sample to sample (Kortekaas and Murraya, 2005;Clark and Sanderson, 1994). Hence, an IRSL response from a quartz aliquot does not necessarily imply the presence of feldspar but could also be due to some mica contamination (or both).…”

“…Kasuya et al [28] studied the annealing effects on the TL sensitivity of lepidolite mica. The natural as well as beta, gamma and electron beam induced TL characteristics of different types of synthetic and natural mica from different origins have been extensively studied by many other researchers [3,[29][30][31][32][33][34][35][36].…”
