Возможность применения микрочастиц оксида тантала в фосфатном стекле для лучевой терапии злокачественных новообразований

Objective: The creation of the medicine for a local radiomodification of tumors. Methods : The level of the secondary radiation on the surface of the phosphate glass powder with the inclusion of tantalum oxide processed by 6 MeV deceleration emission was studied. Medical linear accelerator TrueBeam (Varian, USA), and Semiconductor diode detector PDI 2.0 (Sun Nuclear Corp., USA) having the system of moving in vertical plane and the system of position video recording were used. Results : The presence of the phosphate glass (containing 20% Та2О5) on the surface gave a 63.7% increase to the secondary radiation. It’s around two thirds of the overall level. Conclusion : An opportunity to create a medicine on the basis of phosphate glass, containing tantalum oxide, for local radiomodification of malignant tumors.
