objective(s): the energy resolution of a cadmium-zinc-telluride (czt) solid-state semiconductor detector is about 5%, and is superior to the resolution of the conventional anger type detector which is 10%. also, the window width of the high-energy part and of the low-energy part of a photo peak window can be changed separately. in this study, we used a semiconductor detector and examined the ef...

Background: Separate radon and thoron measurements in soil are very important in assessment of internal exposure due to inhalation of such radioactive gases. Materials and Methods: In this study, a low cost, small size, passive diffusion chamber has been developed for simple measurement of Radon-222 and Radon-220(Thoron) gases separately in soil. The diffusion chamber consists of two films and ...

A charge detector is a vital component in neutrino and dark matter detection. The integration of collector the form flat pads readout modules has been proposed as an optimization method it can reduce noise installation complexity. As substrate, fused silica glass attracted considerable attention due to its low radioactive background properties. In this research, based on application requirement...

PURPOSE Solid state detectors from two independent systems have shown similar over-responses to small electron fields used for treatment of surface lesions. We propose to evaluate the accuracy of solid state detector systems for highly blocked electron fields as a method for clinical dosimetry and determine the cause for any deviations from expected dose-delivery calculations. METHODS A QED D...
