ASN Report 2017
102 ASN report on the state of nuclear safety and radiation protection in France in 2017 Chapter 03 - Regulations The obligations of the owner of the facility are also specified when the action levels are found to have been exceeded. The Order of 22nd July 2004 was followed by the publication in the Official Journal of 22nd February 2005 of an opinion concerning the definition of the actions and work to be carried out in the event of the action levels of 400 and 1,000 Bq/m³ being exceeded. The accreditation conditions for the organisations approved to carry out activity concentration measurements, the measurement conditions and the data transmission procedures are clarified by four ASN resolutions: ཛྷ ཛྷ ASN resolution 2009-DC-0134 of 7th April 2009, amended by resolution 2010-DC-0181 of 15th April 2010, sets the approval criteria, provides the detailed list of information to be enclosed with the approval application and specifies the conditions of issue, verification and withdrawal of approval. ཛྷ ཛྷ ASN resolution 2009-DC-0136 of 7th April 2009 defines the objectives, duration and content of the training programmes for the individuals carrying out radon activity concentration measurements. ཛྷ ཛྷ ASN resolution 2015-DC-0506 of 9th April 2015 specifies the conditions in which radon activity is measured. ཛྷ ཛྷ ASN resolution 2015-DC-0507 of 9th April 2015 sets the technical rules for the transmission of the radon measurement results produced by approved organisations and the conditions for access to these results, pursuant to the provisions of Article R. 1333-36 of the Public Health Code. The list of approved organisations is published in the ASN Official Bulletin on www.asn.fr . The Ordinance of 10th February 2016 also introduced new legislative provisions into the Environment Code, to ensure lasting information of the population and to better estimate the exposure of the French population to radon. These new provisions aim to: ཛྷ ཛྷ consider the radon concentration as an indoor air quality parameter; ཛྷ ཛྷ set up a system of mandatory information of owners, new buyers of real estate and landlords, in areas with a high radon potential; ཛྷ ཛྷ collect the results of the radon measurements taken in homes, at the initiative of the owners or local authorities, in order to gain a clearer estimate of the exposure of the French population to radon. 2.3.2 Other sources of exposure to “enhanced” natural radiation Activities using NORM. Activities utilising raw materials containing naturally occurring radioactive materials are now included in nuclear activities. They will henceforth be subject to the ICPE System once the quantity of radioactive materials exceeds one tonne. This new regulation includes raw materials containing a naturally occurring radioactive material when the radionuclide concentrations exceed the regulation clearance levels (NORM, see point 1.2.2.). Natural radioactivity of construction materials. New provisions have been introduced into the Public Health Code to regulate natural radioactivity in construction materials (Art. R. 1333-38 to R. 1333-44): ཛྷ ཛྷ A reference level of 1 mSv/year in terms of effective dose was introduced to regulate the exposure of persons to gamma radiation emitted by construction materials. ཛྷ ཛྷ The suppliers or producers of natural materials or industrial residues liable to create such exposure must provide a radiological characterisation of these materials or residues; these obligations apply only to materials or residues appearing on a list published by decree (see box opposite). ཛྷ ཛྷ The suppliers and manufacturers of construction products must provide the users with information about the natural radioactivity of the product they market, with the packaging stating the activity concentration index “I” (see box opposite). ཛྷ ཛྷ Depending on the value of I, specific requirements concerning the use of the product could be determined by means of an order. 3. The legal system applicable to basic nuclear installations Basic Nuclear Installations (BNIs) are installations which, due to their nature or to the quantity or activity of the radioactive substances they contain, are subject to particular provisions in order to protect the general public and the environment. FUNDAMENTALS Lists of natural materials and industrial residues concerned by a radiological characterisation obligation and method for calculating the activity concentration index (I). List of natural materials and industrial residues: ཛྷ ཛྷ Natural materials: -- alum shale; -- construction materials or additives of natural igneous origin, such as granitoid rocks (granites, syenite and orthogneiss), porphyries, tuff, pozzolan, lava. ཛྷ ཛྷ Materials containing residues from industries processing naturally radioactive materials, such as fly ash, phosphogypsum, phosphoric slag and residues from the primary production of metals (slag, dross, etc.). Calculation formula for the activities concentration index (I) where C Ra226 , C Th232 and C K40 are the activity concentrations in Bq/kg of the corresponding radionuclides in the construction material.
