Radioactive finds during estate clearance in Norway
Radioactive finds during estate clearance require clarification before objects are handled or passed on. The Norwegian Radiation and Nuclear Safety Authority (DSA) describes industrial measuring sources and certain products containing radioactive luminescent materials. This does not mean every old clock or luminous object is radioactive.
Stop handling and contact DSA
DSA’s poster on radioactive sources in scrap metal says to cordon off the area around a discovered source. Do not handle the source before contacting DSA, or send it elsewhere before the authority has assessed it. For a suspicious find during clearance, clarify further handling with DSA instead of taking the object to a second-hand shop.
Many sources carry a radiation warning symbol and a label identifying details such as manufacturer, serial number and radioactive substance. Explain what is already known about the location and origin. Practical advice: Use available documentation; do not move or open the object to obtain better photographs.
Clarify the waste route
DSA distinguishes radioactive waste from waste below the applicable regulatory thresholds. An object cannot be classified merely by calling it old or unwanted. Radioactive waste is a separate issue alongside other hazardous waste from an estate. Do not assume an ordinary collection site can accept the particular find.
This guidance concerns Norway and was source-checked on 2 November 2026. Use DSA’s contact information for clarification. Once handling has been clarified, you can plan an inspection and ordinary clearance work with OBA. Explain any confirmed restrictions on the assignment.
