ALARP

ALARP: As Low as Reasonably Practicable. In essence, ALARP is the UK definition of ALARA, although they are not the same since ALARP suggests a balance between Risk and benefit (UK Case Law), where as ALARA takes social and economic factors into account. ALARP is key to UK Radiation Protection and introduces a test of reasonableness ensuring that workers work down from Dose Limits rather than up to them.
