IEMA Instructional Set 52.2 Appendix A describes the retention of documents for permanent nuclear medicine job sites. For radiographic installations, the requirements for record retention are found in 32 Ill. Adm. Code Part 360.
One of the items not listed in Part 360, however, is the requirement for CT QA record retention. Based on a discussion with a senior IEMA CT inspector, the minimum retention period for CT QA testing records is one year, or for the period since the last inspection, whichever is longer.
IEMA further recommends that facilities keep all of the previous year’s data while the facility’s technologists collect the current year’s data. This would help prevent inadvertent disposal of records, and provide some overlap to ensure that there is no gap in the CT QA history.
