From 1990 to 1998, estimations of the effective dose from external and internal irradiation due to l 3 7 Cs and >,ACs were carried out for inhabitants in rural villages in theBryansk region, Russia, highly contaminated due to the Chernobyl accident in 1986. Yearly expeditions were conducted in autumn. The external effective dose was estimated from measurements with thermoluminescent (TL)dosemet...

Background: Normoxic type MAGICA gel dosimeters are established for dose quantification in three dimensions for radiotherapy. Objective(s): The ability of MAGICA polymer gel was assessed by experimental measurements method for studying the effect of gold nanoparticles (GNPs) in dose enhancement under the external 18MV radiotherapy practices. <...

Background: High level radiation areas have been recognized on various parts of the earth. Mahallat hot spring region is one of these areas. Study of exposure in these areas can be helpful in investigating the effects of ionizing radiation. Internal and external exposure to the staff was studied. Materials and Methods: Used materials and instruments include: RSS-112 ionizing chamber fo...

wheat is a staple food in pakistan. production of wheat is increased with extensive use of phosphate based fertilizers in agricultural fields. activity mass concentration of primordial radionuclides due to use of phosphate fertilizers in soil enhances the external gamma dose and due to the consumption of wheat food grown on these soils also increases the internal dose. different types of soil, ...

Introduction: Bismuth-based nanoparticles having high atomic number and electron density, besides of being utilized as CT contrast agent, stand as a strongly proposed method for dose enhancement in radiotherapy. Embedded nanoparticle in polymer gel dosimeter poses the first step to assess the dose enhancement capability in nanoparticles. To this end, MAGICA gel dosimeter, whic...
