Abstract

Resumen

Por la demanda de un dispositivo experimental para el posicionamiento de las muestras biológicas

para su irradiación en un canal radial de un reactor nuclear de investigaciones en funcionamiento, se

construyó y se puso en marcha un dispositivo para la colocación y retirada de las muestras en la

posición de irradiación de dicho canal. Se efectuaron las valoraciones económicas comparando con

otro tipo de dispositivo con las mismas funciones. Este trabajo formó parte de un proyecto

internacional entre Cuba y Brasil que abarcó el estudio de los daños inducidos por diferentes tipos de

radiación ionizante en moléculas de ADN. La solución propuesta es comprobada experimentalmente,

lo que demuestra la validez práctica del dispositivo. Como resultado del trabajo, el dispositivo

experimental para la irradiación de las muestras biológicas se encuentra instalado y funcionando ya

por 5 años en el canal radial # 3(

BH#3

Abstract

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.
