| Popis: | In a nuclear weapon accident involving fire or conventional explosion, most of the radiation dose received by people in the immediate vicinity would result from inhalation of 239 Pu. This is accompanied by the nuclide 241 Am, which is much easier to determine by external counting because of the 60 keV gamma ray emission. In the event of an accident a priority would be to identify any people who have had intakes of 239 Pu which were so large that decorporation therapy should he considered. Direct measurement of lung content provides the most rapid and convenient method for assessing intakes by inhalation. A transportable system has been considered as this could be deployed close to the site of the accident and would allow rapid measurements to he made. The feasibility of a transportable 241 Am-in-nose-blow and nasal swab measurement system has also been considered. This would be used to help select people for 241 Am-in-lung measurements. |
