Disposal of Waste
Requirements for the Waste Storage Room
The waste storage room must be marked with signs indicating ionising radiation.
An up-to-date inventory of the radioactive waste, including the radionuclide, must be maintained.
The waste must be capable of being shielded so that persons entering the waste storage room are not exposed to unnecessary radiation.
Preparation of Waste
Radioactive waste must be placed in yellow hazardous-waste containers. The waste must be clearly labelled with the type of isotope and activity in MBq.
Arranging Collection
Radioactive waste must be delivered to an approved waste reception facility. Waste must be delivered annually, or more frequently where necessary. Approved waste service providers are the Institute for Energy Technology (IFE) and Senja Avfall og Miljø AS.
Senja Avfall og Miljø AS is authorised to incinerate waste with an activity concentration not exceeding 10,000 Bq/g.
Disposal of Radioactive Sources
If radioactive sources are transferred to other users outside the University of Oslo (UiO), it must be ensured that the recipient holds the necessary authorisations to receive the source.
Reporting
Waste
Waste must be declared when it is handed over.
The amount of waste generated (radionuclide, weight and activity) must be reported annually, by 15 February, to the Health, Safety and Environment and Emergency Preparedness Unit. This unit is responsible for reporting the information to the Norwegian Radiation and Nuclear Safety Authority (DSA). The data must be summarised for each institute or museum.
Sealed Sources
For sealed radioactive sources registered in the DSA electronic notification system (ems.dsa.no), a new notification must be submitted confirming that the source has been disposed of.
Nuclear Material
The DSA must be notified immediately when nuclear material (U, Th or Pu) is disposed of. The quantity of material must be reported by weight in grams.
