Description
The paper describes both the Co60 irradiation facility and the gamma field at the Agricultural Department of the Research Establishment, Riso. The Co60 irradiation facility contains 1,800 curies of Co60. 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. (author)
Abstract (French)
Le memoire decrit l'appareil d'irradiation au cobalt-60 et le champ sous irradiation gamma du Departement de l'agriculture de l'Organisme de recherche de Riso. L'appareil d'irradiation au cobalt-60 contient une source de 1 800 curies. Des details sont donnes sur la construction ainsi que sur les dispositifs de protection compris dans le plan. Quatre methodes differentes ont ete utilisees pour la dosimetrie: 1. Chambres d'ionisation 2. Calorimetrie 3. Dosimetrie de Fricke 4. 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)Abstract (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. (author)Abstract (Russian)
V doklade opisyvayutsya ustanovka dlya obluchenij na Co60 i pole gammaluchej v Otdelenii sel'skogo khozyajstva Nauchno-issledovatel'skogo tsentra v Rizo. Ustanovka dlya obluchenij na Co60 soderzhit 1800 kyuri Co60. Dayutsya detali konstruktsii, a takzhe ukazyvayutsya mery bezopasnosti, kotorye uchteny v konstruktsii ustanovki. Dozimetriya proizvoditsya pri pomoshchi chetyrekh razlichnykh metodov: 1. Ionizatsionnykh kamer; 2. Kalorimetrii 3. Dozimetra Frikke 4. Fotograficheskikh plenok Daetsya obshchee opisanie polya gamma-izluchenij, vklyuchaya detali raspolozheniya istochnikov. Norma dozirovaniya - priblizitel'no 100r/ch na rasstoyanii v odin metr. Dlya vyrashchivaniya obluchaemykh rastenij beretsya pole s radiusom v 15 metrov. Daetsya kratkoe ukazanie kategorii produktov, podvergaemykh oblucheniyu v dvukh ustanovkakh.
