In the paper is presented a brief description of a cyclotron providing the acceleration of negative hydrogen and deuterium ions to energies of 18 and 9 MeV respectively. The cyclotron is intended to produce short-lived and ultra short-lived radio isotopes. The beam is extracted by charge-exchange of ions by stripping foils. The specific feature of the machine is location of the resonance system inside the vacuum chamber of a shielding-type magnet as well as the vertical position of the median plate of the magnet. The cyclotron has a beamline to transport the beam to remote targets. Two such machines have been manufactured and put into operation: one cyclotron is operated in the PET center of Turku, Finland and the other is functioning in the medical center in Pesochnaya in St.Petersburg, Russia

The REKORD system is intended for the mass radioactive isotopes (MRI) diagnostics of the cardiological, oncological and neurological diseases, which determine the average value of inhabitants lifetime. The potentialities inherent in the MRI diagnostics enable a disease to be identified at the early stage, which is very important for the successful treatment and gives considerable social and economical effects. The system consists of a cyclotron with target systems to produce short-lived and ultra short-lived radionuclides, modules for radiopharmaceuticals synthesis systems built in protection boxes, tomographs for SPECT and PET, which are networked to the regional computer database. The system has no domestic analogues. The advantages over foreign analogues are the universality of the RECORD system and its autonomy, as the isotopes used for diagnostics are produced directly by this system. One sample of the equipment has been delivered to the Central Roentgen Radiological Institute in Pesochnaya and is under operation, excluding PET at the time being. The equipment has been designed and produced mainly in NIIEFA, which is granted the State License certifying the production of medical facilities and the International Quality Certificate. The delivery of the REKORD systems to the regions of the country will allow the problem of the clinical examination of the population of Russia on the modern level of medical diagnostic and information technologies to be successfully solved.

In compliance with requirements of IAEA, thorough inspection of the weld seams of the 1st category should be provided when manufacturing the equipment of nuclear reactors. The potentialities of the accelerators for defectoscopy designed and manufactured in NIIEFA are described in the paper. The accelerators allow the radiographic and radioscopic inspection to be performed in compliance with the ASTM-1-1T standard in the range 20-600 mm for steel.

A new facility for irradiation of shrinkable pipes has been put into operation in Obninsk branch of Physical and Chemical Karpov Institute in the end of 2005. The facility is made on the basis 10 MeV, 10 kW linear electron accelerator UELR-10-10T. This accelerator has high efficiency ~16% due to use solid-state modulator with energy recuperation to supply a klystron. The scanning system allows changing length of the vertical scanning field in the range of 90-170 cm with doses uniformity of +-5%. The pipes with length up to 170 cm and wall thickness of 6 mm are installing in three rows on the perimeter of a drum 3.7 m of diameter. The pipes are rotating around its axis during the irradiation process in order to ensure high uniformity of the doses and hereby good quality of shrinkable goods.
