The calculation of the skin dose received from a small, irradiated fuel fragment requires complete knowledge of the isotopic mixture. But, since significant non-gamma emitting nuclides are present, routine gamma spectroscopy will not identify all of the isotopes in a fuel particle. This article presents a method for determining the age of the particle from its Ce-141/Ce-144 ratio and estimating the activities of the non-gamma emitters based on the known isotopic mixture for spent reactor fuel. Beta skin dose is then calculated using the Loevinger equation for a n infinite plane source, while the gamma component may be calculated using a point source method. An example skin dose calculation is presented for a fuel particle found on a worker's clothing.
