Pennsylvania State University proposes to procure and install a quantity of 60Co sufficient to allow irradiation dose rates up to 2Mrads/hour, or >100 krad/hour at the end of an additional 20 years of use. The new cobalt pencils will be loaded into the source holder, which has already been characterized and used for past irradiations.
