If the PH is scheduled for an extended leave (i.e., one month or more) from the University (e.g., sabbatical), the RSO must be notified regarding the status of the permit during his/her absence. The PH may designate an individual to serve as acting PH during his/her absence; however, the acting PH is required to meet the same minimum requirements of any PH. Alternatively, the PH may request the permit be considered inactive until he/she returns to the University. In this case, specific information regarding the storage or disposal of any radioactive material currently on the PH's inventory should be included in the notification.
