Records of the monitoring of radiation from nuclear substances.
Content & Scope
The University is required to monitor radiation through control of inventories of nuclear substances and testing for contamination.
This records class excludes radiation dosimetry records for individual workers.
The records include open source nuclear substance inventories and usage records, open source contamination survey forms, and sealed source leak tests.
For dosimetry records, see HS35 – Radiation Dosimetry Reports.
- Sealed source leak tests: 3 years.
- Open source use and monitoring records: 3 years after disposal, except that contamination survey forms may be destroyed 3 years after completion of the survey.
Responsible Units should document the disposal/destruction of official records using the University records destruction form or equivalent documentation, to verify that we are following our records retention rules.
