Description

In the present study thermoluminescence (TL) glow curves of commercial and gamma (0.001 Gy to 100 kGy) exposed neodymium oxide (Nd2O3) have been investigated. The commercial glow curve is simple with TL peaks at 310, 350 and 385 oC. The TL sensitivity was enhanced to ∼4.7 times the original value when the investigated material was subject to pre-heating treatment at 800 oC for 1 h. The effect of storage time at room temperature has been monitored for different γ-doses. The combination of good γ-dose response and high stability of defects offer the possibility of applying the investigated material to γ-ray dosimetry in radiotherapy and experimental radiology range
