Abstract

The buildup factor is becoming a required parameter for exposure and energy absorption in the area of radiation physics for shielding, dosimetry, health physics and medical physics. In this research, photon buildup for dysprosium doped lithium magnesium borate glasses system has been investigated. Photon energy absorption buildup factors and photon exposure buildup factors were computed for the chosen glasses using the five-parameter geometric progression fitting method in energy range of 0.015 MeV to 15 MeV. ‎Also, effective and equivalent atomic numbers were calculated for these compositions and discussed for possible implementation in radiation dosimetry. ‎

Highlights

• Four different compositions of the dysprosium doped lithium magnesium borate glasses system are investigated.

• Various factors for selected glasses system is calculated using the five-parameter geometric progression fitting method.

• The G-P fitting method is beneficial technique for low-Z as well as high-Z element materials
