protocol drawn up by
Placoplâtre
and the requests
formulated by ASN in its opinion of 20th March 2015.
The conclusions of this inspection were reported to the
members of the Fort de Vaujours CSS on 9th July 2015. On
13thNovember 2015,
Placoplâtre
presented the responses
to the observations it had received to the members of
the CSS. Lastly, a second unannounced inspection was
also carried out on 17th December 2015 to verify that
the radiological characterisation and environmental
monitoring measures had been carried out.
In collaboration with the ARS of Ile-de-France and
the nuclear safety and radiation protection mission
of the Ministry of the Environment, Energy and the
Sea, ASN helped define a strategy for monitoring and
managing the scattered radioactive contaminations of
the Coudraies and Clos Rose quarters of Gif-sur-Yvette
resulting from the past activities of the company
Société
Nouvelle du Radium.
The proposed measures consist in
updating the prescriptions and recommendations of the
local urban development plan of Gif-sur-Yvette and in
2016 conducting a campaign of radon measurement
in the interior air of the houses concerned.
Lastly, the Radium Diagnostic operation has been
launched in Ile-de- France since 21st September 2010.
The government decided to perform the diagnoses free
of charge in order to detect, and where applicable treat,
any legacy radium pollution. This operation, which is
placed under the responsibility of the Prefect of the Ile-
de-France region, the Prefect of Paris, and is coordinated
by ASN, concerns 84 sites in Ile-de-France.
Thirty-six sites had been examined by the end of 2015.
Eight of these 36 sites were able to be excluded outright
because the buildings are too recent with respect to
the period of potential manipulation of radium to be
able to have any radioactive contamination. On the
remaining 28 sites, more than 430 diagnoses were carried
out; most of the sites concern one building with many
apartments, or several individual plots. Twenty-one
diagnoses revealed traces of radium in premises that
are now undergoing rehabilitation. The measured levels
of activity are low and the exposure does not present
a health risk for the occupants.
For the occupants and owners of the contaminated
premises, personalised assistance is being provided
to apply the necessary protection measures and start
the rehabilitation work, paid for by the State. The
rehabilitation work has been completed on six sites,
is in progress on ten sites and under preparation for
five sites.
2. ADDITIONAL INFORMATION
2.1 Monitoring of organisations
approved for radiation protection
controls
In 2015, ASN carried out six head-office audits and
seven unannounced supervisory inspections as part of
the monitoring of organisations approved for radiation
protection controls in Ile-de-France. These turned out
to be satisfactory on the whole. This being said, many
approved organisations do not notify their operations
exhaustively on the specific tool put in place by ASN,
even though this notification is mandatory so that ASN
can carry out unannounced inspections.
2.2 Informing the public
ASN held a press conference in the Paris division on
9th June 2015 to present the results of its regional action.
Seminar on radiation protection of patients, workers and the environment in nuclear medicine,
September 2015.
