The Regulation prescribes the requirements for the physical protection of sources of ionising radiation. An operator within whose controlled area a source of ionising radiation is located for which a special permit (licence) or permit for operations with sources of ionising radiation is required shall ensure fulfilment of the requirements for the physical protection of the source referred to in order to prevent unauthorised operations - sabotage, theft, unauthorised removal, alteration or use of the protected source, damage or destruction thereof. Compliance with the requirements for physical protection shall be controlled by the Security Police and the Radiation Safety Centre. The Radiation Safety Centre shall consult the Security Police regarding possible radioactive contamination and exposure at the protected facilities due to unauthorised operations.
