The San Onofre Nuclear Generating Station (SONGS) has experienced significant fuel fragment contamination problems, and as a result, a large number of skin dose evaluations have been performed. This paper examines the methods that have been used to estimate the magnitude of the dose via field measurements and to calculate the final dose of record for contamination incidents involving microscopic irradiated fuel fragments (fleas). The initial estimates are performed using standard survey instruments (i.e., friskers and ion chambers) corrected for instrument response due to particle size and energy. The method used for final dose calculations is composed of two steps: (a) determining the isotopic content of the particle by dating it and (b) calculating the delivered dose using a Loevinger beta dose equation or the VARSKIN computer code. The gamma dose is determined by using a gamma point source equation.
