Legal Compliance

• Verify in advance that every action you take—including purchasing, importing, or transferring radioactive items—is lawful where you live and where the material will be used or stored.

• Penalties for non-compliance can include fines, criminal charges, and imprisonment.

Health and Safety

• Ionising radiation can cause serious injury or illness. Follow the ALARA principle (“As Low As Reasonably Achievable”) by minimising time of exposure, maximising distance, and using appropriate shielding and personal protective equipment (PPE).

Emergency and Reporting

• If you find a suspicious object that is not a naturally occurring radioactive material (NORM) and it emits more than 2.0 µSv/h, immediately secure the area, limit access, and notify the competent local authority.

• If the dose rate exceeds 10.0 µSv/h, an urgent report to emergency services is mandatory. Such sources may pose an acute hazard to you and the public.

• The values mentioned above are common but may differ from the standards adopted in your country. Familiarise yourself in advance with national and regional procedures for incident response and source recovery.
