introduction: nowadays new radiochromic films have an essential role in radiotherapy dosimetry. properties such as high sensitivity, good reproducibility, high spatial resolution, easy readout and portability have made them attractive for dosimetry, especially in high-dose-gradient regions. material and methods: in this study, electron-beam dose distributions in homogenous and heterogeneous pha...

the effect of evaporation rate on structural, morphological and optical properties of electron beam evaporated cds thin films have been investigated. cds thin film deposited by electron beam evaporation method in 12nm/min and 60nm/min evaporation rates on glass substrates. x-ray diffraction, scanning electron microscopy, uv-vis-nir spectroscopy and atomic force microscopy were used to character...

cross linking of high density polyethylene (hdpe) was first performed via high energy10 mev electron beam (eb) irradiation. hdpe was also cross linked withdicumyle peroxide (dcp).the gel content of samples was determined by solvent extraction.degree of cross linking was evaluated by hot set apparatus; as well .in order to clarify the effectof nature of cross linking, correlation of electrical p...

a total of 300 one-day old male broilers (cobb 500) were randomly divided into four treatment groups. the groups comprised of 15 birds each, and were defined by diet and the birds in each group were fed 0 (control), 3, 5, or 7 kgy electron-beam irradiated diets. a total of 5 replicates were performed. the chemical composition of the diet was not affected by irradiation.irradiation doses of 5 an...

The NPDGamma collaboration has completed the construction of a pulsed cold neutron beam line on flight path12 at the Los Alamos Neutron Science Center (LANSCE). We describe the new beam line and characteristics of the beam. We report results of the moderator brightness and the guide performance measurements. FP12 has the highest pulsed cold neutron intensity for nuclear physics in the world.
