RODRIGUEZ - GUAL, Maritza; MAS - MILIAN, Felix; DEPPMAN, Airton  y  ROGERIO PINTO - COELHO, Paulo. Biological samples positioning device for irradiations on a radial channel at the nuclear research reactor. Ingeniería Mecánica [online]. 2010, vol.13, n.2, pp. 39-48. ISSN 1815-5944.

For the demand of an experimental device for biological samples positioning system for irradiations on a radial channel at the nuclear research reactor in operation was constructed and started up a device for the place and remove of the biological samples from the irradiation channels without interrupting the operation of the reactor. The economical valuations are effected comparing with another type of device with the same functions. This work formed part of an international project between Cuba and Brazil that undertook the study of the induced damages by various types of ionizing radiation in DNA molecules. Was experimentally tested the proposed solution, which demonstrates the practical validity of the device. As a result of the work, the experimental device for biological samples irradiations are installed and operating in the radial beam hole #3(BH#3) for more than five years at the IEA-R1 Brazilian research reactor according to the solicited requirements the device. The designed device increases considerably the type of studies can be conducted in this reactor. Its practical application in research taking place in that facility, in the field of radiobiology and dosimetry, and so on is immediate.

Palabras clave : research nuclear reactor; sample positioning device; radial channel; appropriate technology.
