(11). Americium-241 ww partly delivered at the accident, partly grown up from the decay of 241Pu in situ on the sea floor and also during storage in the laboratory. The fact that all results for americium had to be corrected to the date of collection render these results and the interpretation of data more uncertain. Shortly after the accident detailed nuclear track autography and microscopic studies of melted crust samples were conducted (12). The studies showed the plutonium to be in form of oxide particles with a very wide size distribution with a median diameter of 2ium. The particles
