The study of radioisotopes to measure regional lung function, using radio­ active gas, is presented.

Radioisotopes, also known as radionuclides, are atoms with unstable nuclei that emit ionizing radiation [...]

Cancer is one of the leading cause of death worldwide.1 In 2010, a total of 1,529,560 new cancer cases and 569,490 cancer deaths were estimated in the United States alone.1 Despite advances in our understanding of tumor biology, cancer biomarkers, surgical procedures, radioand chemotherapy, the overall survival rate from cancer has not improved significantly in the past two decades. Early detec...

Abstract We present the findings of an extensive examination on newly designed CdO-rich and transparent glass shields for nuclear medicine facilities in lieu traditional unfavorable materials, such as lead concrete. Gamma-ray transmission factors are determined using a variety diagnostic, therapeutic, research radioisotopes, including 67 Ga, 57 Co, 111 In, 201 Tl, 99m Tc, 51 Cr, 131 I, 58 137 C...
