Physical and dosimetric properties of NaCl pellets made in-house for the use in prospective optically stimulated luminescence dosimetry applications

In this paper, NaCl pellets are produced in-house from ordinary household salt using simple and accessible methods, for the purpose of suggesting a cost-effective and available tool for various optically stimulated luminescence dosimetry applications. First, the pellets are investigated in terms of optimal configuration by varying combinations of grain sizes and compression forces. Then, the pellets with the optimal configuration are further investigated in terms of dosimetric properties such as signal-dose response, dose estimation, reproducibility, radiation induced sensitisation, detection limits and signal stability over time. The radiation induced OSL signals are read at room temperature and dose estimations are performed using one calibration dose.
