Abstract

The paper describes both the Co{sup 60} irradiation facility and the gamma field at the Agricultural Department of the Research Establishment, Riso. The Co{sup 60} irradiation facility contains 1,800 curies of Co{sup 60.} Details of the construction are given together with the safety precautions which have been included in the design. Dosimetry has been carried out by four different methods: 1. Ionisation chambers, 2. Calorimetry, 3. Fricke dosimeter, 4. Photographic films. A general outline is given of the gamma field, including details of source position. The dose rate is approximately 100 r./hr. at a distance of 1 m. An area of radius 15 m is used for the growing of plants under irradiation. A brief indication is given of the class of products which have been irradiated in the two facilities.

Pellicules photographique s On donne un apercu general du champ gamma, ainsi que des details sur la position de la source. L'intensite de dose est de 100 R/h environ a une distance de 1 m. Une zone d'un rayon de 15 m est utilisee pour la croissance des plantes soumises a l'irradiation. Des indications sommaires sont donnees sur la categorie des produits qui ont ete soumis a l'irradiation dans les deux installations. (author) [Spanish] Los autores describen la instalacion de irradiacion con cobalto-60 y el campo de irradiacion gamma del Departamento de Agronomia del Instituto de Investigaciones de Riso. El dispositivo de irradiacion consiste en una fuente de cobalto-60 de 1 800 curies. En la memoria se facilitan detalles relativos a su construccion y a las normas de seguridad que se han observado en el proyecto. Las determinaciones dosimetricas se han efectuado con ayuda de cuatro tipos de aparatos diferentes: 1. Camaras de ionizacion 2. Calorimetros 3. Dosimetros de Fricke 4. Peliculas fotograficas. En la memoria se hace asimismo una descripcion general del campo de irradiacion gamma y se dan detalles referentes a la posicion de la fuente. La intensidad de irradiacion es de unos 100 roentgens/hora a una distancia de 1 m. Las plantas sometidas a la irradiacion se cultivan en un campo de 15 m de radio. Se indican brevemente los diferentes productos que se han sometido a irradiacion en las dos instalaciones.
