Recent years have seen the increasing use of passive dosemeters that have high sensitivities and, in laboratory conditions, detection limits of <10 µSv. However, in real operational use the detection limits will be markedly higher, because a large fraction of the accrued dose will be due to natural background, and this must be subtracted in order to obtain the desired occupational dose. No matt...

Brachytherapy reduces the post radiation sequalae as dose required is lower than external beam therapy (EBRT) and limits area of exposure. This case report outlines two different patients managed by fabrication carrier prosthesis for duration brachytherapy.

background: 3dcrt (three-dimensional conformal radiotherapy) and imrt (intensity-modulated radiotherapy) has provided us with tools to delineate the radiation dose distribution of tumor targets. however, the precision of radiation can be compromised by respiratory motion, which usually limits the geometric and dosimetric accuracy of radiotherapy. the purpose of this study is to evaluate the imp...

BACKGROUND Immunotherapy dose recommendations for allergens specified in practice parameter updates have varied from version to version, and no convenient methods are available to incorporate dose changes or targets into maintenance vial formulations for patients. OBJECTIVES To compare the allergen immunotherapy dose recommendations published between 2003-2011, and to provide math-free dosing...

Introduction: The main purpose of this study was to compare transient ischemic dilation (TID) ratios in SPECT-low dose CT and SPECT Myocardial Perfusion Imaging (MPI) by application of different quantitative programs and quantify the possible shift in the upper normal limits of TID ratio in the SPECT-CT MPI. Methods: 149 Patients with low pre-test probability for coronary artery disease (CAD),...

background: vegetation (food stuff) is grown in soil that contains many radioactive elements such as 238u (uranium), 232th (thorium) and 40k (potassium), which may get deposited either due to radioactive fallout or/and by absorption from the soil and can pose serious health hazards. materials and methods: natural radioactivity, radiological hazards and annual effective dose assessment was carri...
