Scope :as far as workers may be exposed

to a risk due to ionising radiation coming from :

•Registered or authorised nuclear activities •Nuclear installations •Radon, NORM Industries •Emergency situations •Existing exposure situations

Under the responsibility of the employer

Radiation protection enforcement



EFFECTIVE DOSE = The sum of the effective doses received

through external and internal exposure must not exceed 20 mSv

over twelve consecutive months

EQUIVALENT DOSE

SKIN, EXTREMITIES = 500 mSv

LENS = 150 mSv

over twelve consecutive months

(Methodology for dose calculation :ministerial order 01/09/2003)

Principles and implementing provisions

Limits for workers for usual conditions of work



Risk assessment at worplace, under the responsibility of the employer

NON EXPOSED workers

CATEGORY B workers

Effective dose > 1 mSv in a year or Equivalent dose >1/10 of the relevant limit in a year

CATEGORY A workers

Effective dose > 6 mSv in a year or Equivalent dose > 3/10 of the relevant limit in a year

Categorization of Workers



Medical examination : every year at minimum for category A and B workers Individual medical file : Ability form Results and dates of the examinations Dosimetric results : operationnal, passive and internal dosimetry The occupational physician issues an individual form of the medical follow-up for any exposed worker

Medical surveillance by Occupational Physician




External dosimetry •Supervised area

Individual passive dosimetry •Controlled area

Individual passive dosimetry Individual operational dosimetry (Managed by the qualified expert under

the responsibility of the employer) Internal dosimetry : Bioassays, anthroporadiametry

Dosimetry organisms approved by ASN

Dosimetric monitoring




Results of : •Individual external passive dosimetry •Individual internal dosimetry

are directly sent by the approved dosimetry organisms to the national dose register (SISERI) managed by the Institute of radiation protection and nuclear safety (IRSN)

Results of individual operational dosimetry are directly sent by the qualified expert of the employer to the national dose register (SISERI) managed by the Institute of radiation protection and nuclear safety (IRSN)

Internal exposure monitoring calculated dose in air crew Operational dosimetry

Operational dosimetry

Dose registration at each exit

Radiation protection officers (RPO)

transmit all the individual results on

a weekly basis

Passive dosimetry Aircrew doses Internal exposure monitoring

The individual dose is monthly calculated by

each company (with SIEVERT) taking into

account the individual flight plan

Each company transmits all the individual

results on a monthly basis

In vivo and/or in vitro measurements performed

by accredited labs approved by the authority

Each lab transmits all results on a monthly basis

Internal dose is calculated and transmitted by

occupational doctor

Measurements performed by 9 accredited

labs approved by the authority

Each lab transmits all the individual

results on a monthly basis

Radiation protection officer rights

Effective dose on the last 12 months

All active doses on the last 12 months

Occupational doctor rights

All results and doses ●Workers

●Labour and radiation protection inspectors ●Research organisation

Access on written request

General operating principle of SISERI



Training to radiation protection for exposed workers entering supervised or controlled areas

Periodically repeated At minimum every 3 years Notice on the risks related to an operation in a controlled area

Worker training Under the responsibility of the employer



•Each empoyer is responsible for his workers radiological protection

•Undertaking insures coordination between its own prevention actions and the ones taken by the employer of ouside workers

•Undertaking must give to the employer of the outside workers all the informations and instructions relevant to radiological protection •Formal agreements should be concluded between undertaking and employer of the outside workers concerning the supply of individual protection devices and individual exposure instruments

In nuclear facilities :

operator and employer of the outside workers shall define jointly prevention actions Operator shall make sure that these actions are implemented before, during and up to the end of the work.

Requirements concerning employers of outside workers and undertaking



•Concern companies providing maintenance services, intervention works

•List of activities set up

•Certification for carrying out works in ionising radiation

•Certification provided by approved organisms

•Graded approach to the implementation of the system, applying requirements that are commensurate with the ionising radiation risks

Ministerial order in preparation

Requirements for companies providing services



•National dose register / centralised national network

•Issuance of individual radiological documents for outside workers (Radiation passbook)

•Electronic information exchange between countries to guarantee a protection of cross-boarder outside workers (web-based)

The way forward
