Radiation incident definition

Radiation incident means the loss of control of a radioactive source or materials or the unintended exposure of an individual to radiation that exceeds the limits in this chapter.

Radiation incident means an abnormal occurrence in which a source of ionizing radiation is temporarily out of control, but in which no significant dispersal of any radioactive substance takes place, and in which no person receives or is likely to have received a dose equivalent or an intake of any radioactive substance more than twice that which is likely to occur during any operation normally carried out with that source of ionizing radiation and for the purposes of this definition, an abnormal occurrence involving radioactive substances is not to be regarded as being a radiation incident unless:

More Definitions of Radiation incident

Radiation incident means a single event or series of events which occur during the use of a Group IV hazardous substance, and which result in the harmful or potentially harmful exposure of any person to ionising radiation as a direct result of the use of such substance.
