With respect to Radiation Protection, risk assessment is essentially about assessing risk of radiation exposure in order to mitigate that exposure, ensuring doses are as low as reasonably practicable (ALARP) and certainly below Dose Limits. In the UK risk assessment is a requirement of Regulation 7 of the Ionising Radiations Regulations 1999. A basic risk assessment requires that the radiation hazards are identified, an assessment of what can go wrong to realise those hazards is made, prediction of how likely something will go wrong and produce the hazard, and finally what are the consequences of the radiation exposure. Radiation risk assessments can be simple or complicated depending on the circumstances.
