  The first activity on proton beam application to radiography was started about 45 years ago. Success of proton radiography was based on main characteristics the thickness of transmitted object, a spatial resolution which were significantly better then for X-ray. The possibility of the experiments executed according to the scheme "proton-object-detector" are limited with proton multiple scattering in object. In the end of 90-s in the USA it was shown that negative effects of multiple scattering could be suppressed by placing a system of magnetic lenses between an object and detector. Area of application for radiographic setup with protons becomes wider in comparison with traditional X-ray system. Use of proton radiography it becomes possible to study dynamic objects as protons could be removed from the accelerator by short pulses. In Russia first experiments on radiography with accelerated charged hadrons were carried out on the TWAC-ITEP accelerator facility in 2003. In those experiments a beam of carbon ions with energy of 200MeV/u without a magneto-optical system was used for radiographic purpose. From 2005 at ITEP operated the proton radiography facility using the magneto-optical system with different parameter of magnification "-1", "-4" and "-8". The review of the experimental activity on proton radiography аt ITEP is presented.

  The D.V.Efremov Institute (NIIEFA) is the leader in Russia in designing and manufacturing of the accelerating equipment for medicine. About one hundred of linear accelerators for the beam therapy and more than forty cyclotrons for production of radiopharmaceuticals have been designed, manufactured and delivered to clinics of Russia and some foreign countries. The equipment designed and manufactured in NIIEFA in its technical characteristics is on a par with foreign analogs and sufficiently cheaper in expenditures for personnel training, hardware and software compatibility, warranty and post-warranty service, delivery of spare parts and updating. In accordance with Federal Targeted Programs on the development of medical and pharmaceutical industries up to 2020, the production facilities, material and technical resources have been prepared for the organization of serial production of cyclotrons and gamma tomographs.

  The INR linear accelerator provides a high intensity beam of intermediate-energy protons for both applied and fundamental research. The beam at 160 MeV can be extracted from the main line and delivered to an isotope production facility. Specially designed targets are irradiated at the facility to produce Curie amounts of various radionuclides for medicine and industry, namely, 82Sr, 103Pd, 117mSn, 225Ac, 223Ra, 109Cd, 22Na. Production rate of radionuclide is usually limited by the ability of target to sustain the high intensity beam. Targetry development comprises: - Choice of target material with appropriate nuclear (cross-section of a desired radionuclide) and thermal physics (thermal conductivity, heat capacity) properties, as well as material for target encapsulation; - Analysis of interaction of proton beam with target material. Parameters of beam, cooling water, and other factors are being investigated to result in tentative geometric parameters of target. Spatial-energetic degradation of beam is evaluated by a Monte Carlo code STRAGL*; - Simulation of temperature generated in the target due to heat release of protons. Computations are performed by means of the software complex ANSYS; - Fabrication and irradiation of experimental targets; control of target integrity during irradiation and after it via monitoring the electroconductivity and radioactive impurities of cooling water, visual inspection of target, etc., optimization of target design for routine production.
