Kinetic parameters for the Na₂SO₄ irradiated at different γ-ray doses.

γ-Ray dose (K Gy)	𝑇max (°C)	𝐸𝑔 (eV)	𝑠 (s^−1)
0.25	170	0.18	0.63 × 10^12
1.00	172	0.17	0.91 × 10^12
2.00	174	0.19	1.24 × 10^12
3.00	176	0.20	6.28 × 10^12
3.50	180	0.18	7.04 × 10^12
4.00	185	0.17	7.16 × 10^12

𝑇_max, 𝐸_𝑔, and 𝑠 are the maximum TL glow peak temperature, activation energy, and frequency factor of the Na₂SO₄, respectively.
