Pb-free Radiation Shielding Glass Using Coal Fly Ash
In this work, Pb-free shielding glass samples were prepared by the melt quenching technique using subbituminous fly ash (SFA) composed of xBi2O3 : (60-x)B2O3 : 10Na2O : 30SFA (where x = 10, 15, 20, 25, 30 and 35 by wt%). The samples were investigated for

Impact of $ \mathrm{Eu_2}\mathrm{O_3} $ and $ \mathrm{Er_2}\mathrm{O_3} $ on the gamma radiation shielding performance of $ \mathrm{B_2}\mathrm{O_3} $+CaO+ZnO+BaO+$ \mathrm{Eu_2}\mathrm{O_3} $ + $ \mathrm{Er_2}\mathrm{O_3} $ glass system [PDF]
In this study, four rare earth-doped BaO-ZnO-CaO-$ \mathrm{B_2}\mathrm{O_3} $ glass samples were prepared using melt-quenching technique. The density of the glass was determined using Archimedes' method and found in range 3.28-3.72 $ gcm^{-3} $.

Mailed thermoluminescent dosimeter determination of entrance skin exposure and half-value layer in mammography [PDF]
A method of providing in vivo measurement of entrance skin exposure for mammography using mailed thermoluminescent dosimeters has been developed. The dosimeters are calibrated to 137Cs (662 keV), and a correction is applied to account for energy response.
