Definitions

  • the holders in the compartments [58] Field of Search 250/84, 106 S, 106 SC, and the capsules in the holders are disposed so that by 250/106 R, 108 R a suitable arrangement of the capsules, the desired intensity and geometry of the betaradiation field is se- [56] References Cited cured.
  • the present invention relates to beta-irradiation equip-ment intended to irradiate solid, liquid and gaseous physical and chemical specimens and also biological objects for the purpose of changing their physicochemical state, structural and biological properties.
  • beta-irradiation units incoporating an irradiator which uses a substance containing a betaemitting radioisotope.
  • Still another object of the present invention is to provide a beta-irradiation apparatus providing for the charging and re-charging of the irradiator with a substance containing a beta-emitting radioisotope in a simple way.
  • plugs 4 and 5 (FIGS. 2 and), one of which, 5, can readily be removed.
  • the operator has only to deal with one capsule 3 at a time, because the capsules 3 are arranged in the holder 2 one above another and shield each other.
  • the beta-irradiation apparatus disclosed herein despite its relatively small overall dimensions, small weight and low cost (e.g., 800 X 500 X 500 mm, 600 kg, and 300 roubles without the radioisotope, respectively), produces fluxes of beta radiation of considerable intensity (the radiation rate in air is up to 50 rad/- sec) in a space measuring 250 X 250 X 150 mm, and enables the key radiation parameters to be varied between broad limits by re-grouping the holders and capsules.
  • the apparatus disclosed herein can be used in a wide range of laboratory studies into the effects of ionizing radiations in chemistry, physics, biology and technology. With an irradiator of increased activity and extent, this type of apparatus can be used commercially, for example in irradiation chemistry and for the sterilization of medical products.
