Radiation protection in handling ionizing radiation sources

The basic stages of ionizing radiation interaction with live matter are summed up. The effects are described of radiation on cells and tissues, the relationship is described of the dose (threshold, threshold-free) and the response in organisms, early and delayed radiation effects. The system has been laid down of limiting radiation doses and its basic principles are described. Concrete radiation dose limits have been adopted for planning and controlling work safety in handling radiation sources. Consistent inspection is implemented of work safety, controlled areas defined and personnel and workplace monitoring provided. An emergency plan is designed for the case of a radiation accident.
