In ISO9236-1 there is no description of the processing method for the sensitometric determination of an x-ray film by the film-screen combination method. But it states that when the film-screen combination system is being determined, either manual processing or automatic processing can be adopted. The different processing procedures will result in wide different sensitivities and average gradie...

This short note investigates the energy response characteristics of a relatively new high sensitivity radiochromic film (XR type T) and compares it to other radiochromic and radiographic films and thermoluminescent dosimeters. Results show that the energy response of the new XR type T film is relatively large over the range of therapeutic energies from 50 kVp superficial x-ray treatment to 18 M...

abstractbackgrounds: md-55-2 is one of the radiochromic film models with the sensitivity suitable for dose measurements ranging from 5 to 100 gy.  however, this lower limit makes the film impractical for its applications in many areas such as brachytherapy source dosimetry.materials and methods: in this project, the useful range of the film has been extended by using a multilayer film technique...

The Mn K edge X-ray absorption near edge structure (XANES) of Pr0.67Sr0.33MnO3 films with different thicknesses on (001) LaAlO3 substrate was measured, and the effects of strain relaxation on film properties were investigated. The films showed in-plane compressive and out-of-plane tensile strains. Strain relaxation occurred with increasing film thickness, affecting both lattice constant and MnO...
