Determination of half value layers of X-ray equipment using computed radiography imaging plates [PDF]
Physica Medica, 2012 A method for determining half value layers (HVLs) of inverter-type X-ray equipment using a computed radiography (CR) systems was developed. This method is similar to the traditional method, where the air kerma (K) is measured using an ionization based dosimeter and increasing aluminum (Al) absorber thickness, but utilized an imaging plate (IP) and the ...

Rigorous construction of ground state correlations in graphene: renormalization of the velocities and Ward Identities [PDF]
, 2009 We consider the 2D Hubbard model on the honeycomb lattice, as a model for single layer graphene with screened Coulomb interactions; at half filling and weak coupling, we construct its ground state correlations by a convergent multiscale expansion ...

Effect of rare earth dopants on the radiation shielding properties of barium tellurite glasses
Nuclear Engineering and Technology, 2021 Rare earth doped barium tellurite glasses were synthesised and explored for their radiation shielding applications. All the samples showed good thermal stability with values varying between 101 °C and 135 °C based on dopants. Structural properties showed
