Complementarity of Safety and Protection
Complementarity of Safety and Protection : The presence of a source in the vicinity of a person (target) could potentially, in the absence of measures for safety and protection, give rise to exposure of the target to radiation. The figure is a schematic representation of such a situation of potential exposure: potential exposure is the risk of exposure to radiation. Safety concerns both risks under normal circumstances and risks as a consequence of incidents, as well as other possible direct consequences of a loss of control over a nuclear reactor core, nuclear chain reaction, radioactive source or any other source of radiation. Safety involves the prevention or reduction of potential exposure and other risks (for the minimization of danger). Radiation protection involves the prevention or reduction of radiation exposure (for the protection of health). Safety is thus primarily concerned with maintaining control over sources, whereas radiation protection is primarily concerned with controlling exposure to radiation, whatever the source, to mitigate its effects. Clearly protection and safety are closely related: protection is much simpler if the source in question is kept under control, so safety necessarily contributes towards protection. There are many different types of sources of radiation, and hence safety includes the safety of nuclear installations, radiation safety, the safety of radioactive waste management and safety in the transport of radioactive material
