Evaluation of the equivalent dose rates due to neutrons emitted by plutonium metal, plutonium oxide, and plutonium fluoride: graphs; Evaluation des debits d'equivalent de dose dus aux neutrons issus du plutonium metal, de l'oxyde de plutonium, du fluorure de plutonium. Abaques (in French)
In irradiated fuel processing plants, the personnel concerned with radloprotection often require a rapid estimation of the equivalent dose rates due to neutrons emitted by plutonium or plutonium compound sources (sources having different physical and geometrical characteristics). GraphPS are presented which facilitate rapid determinations. Expressions enabling the specific emissions of Pu or Pu compound sources to be calculated are given, the contribution of the flssion neutrons produced being taken into consideration. This Pu can arise from fuels having different physical characteristics. As an example of the application of the techniques outlined, graphs enabling the equivalent dose rates to be evaluated in contact with xx at some distance from sources of Pu metal or Pu oxide or fluoride are presented, the Pu being obtained natural U rods having been irradiated at different burn up in uranium-graphite-gas type reactors.
