Half-value layer measurement: simple process method using radiochromic film [PDF]
Australasian Physics & Engineering Sciences in Medicine, 2009 Although the half-value layer (HVL) is one of the important parameters for QA and QC, constant monitoring has not been performed because the measurements using an ionization chamber (IC) are time-consuming and complicated. To solve these problems, the use of radiochromic film (GAFCHROMIC XR TYPE R: GAF-R) with step-shaped aluminum (Al) filters ...

Measurement of Half-value Layer in Mammography
Japanese Journal of Radiological Technology, 2003 The half-value layer (HVL) of an X-ray beam for film-screen mammography is considered an important parameter for image quality and patient dose. Thus, HVL must be measured in accordance with The Manual of Accuracy for Mammography printed by the Japanese Society of Radiological Technology.

The Precision of Half-value Layer Measurement on Mammography
Japanese Journal of Radiological Technology, 2011 The half-value layer (HVL) is an important index of the image quality or radiation risk in mammography. Radiation risk of the breast tissue is evaluated with the average glandular dose. The HVL index is indispensable for the average glandular dose computations.

Pb-free Radiation Shielding Glass Using Coal Fly Ash
Journal of Mathematical and Fundamental Sciences, 2015 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
