Paragraph 3: Principles of justification, optimisation and limitation

I.-The person responsible for a nuclear activity shall demonstrate that his activity complies with the principle of justification set out in 1° of Article L. 1333-2 , taking into account : 1° The protection of the interests mentioned in Article L. 1333-7 ; 2° The effectiveness or potential consequences of the nuclear activity, process, device or substance, as well as its effectiveness in relation to the information available concerning other…

In order to implement the principle of optimisation defined in 2° of Article L. 1333-2, the person responsible for the nuclear activity or the competent authority may set dose constraints for the exposure of the general public to ionising radiation expressed in terms of individual effective or equivalent dose. These constraints may not exceed the dose limits laid down in Article R. 1333-11. The person responsible for the nuclear activity…

I.-For the application of the limitation principle defined in 3° of Article L. 1333-2, the effective dose limit for exposure of the general public to ionising radiation resulting from all nuclear activities is set at 1 mSv per year, with the exception of the specific cases mentioned in Article R. 1333-12. II – The equivalent dose limit is set for : 1° The crystalline lens: 15 mSv per year ;…

The dose limits defined in Article R. 1333-11 do not apply to persons subject to the following exposures: 1° Exposure of patients as part of a diagnosis or therapeutic treatment based on ionising radiation from which they are benefiting, as provided for in I of article L. 1333-18 ; 2° Exposure of persons who, having been informed of the risk of exposure, voluntarily and privately participate in the support and…
