Biological Dosimetry Laboratory (LDB)


The Biological Dosimetry Laboratory (LDB) is located at Fontenay-aux-Roses, in the Paris region and managed by Céline Baldeyron. In 2008, the laboratory obtained accreditation from COFRAC for its cytogenetic analysis activity.


Biological dosimetry is the assessment of the impairment of an irradiated person based on the radiation-induced variations of certain biological parameters. Biological dosimetry is complementary to clinical symptomatology and physical dosimetry.

 

 

Summary

 

 

 

Context and research themes

 

The Biological Dosimetry Laboratory is in the field of main research thematique "Biological doimetry and indicators".

 

 

Research axes

 

  • Set up an operational organization and means enabling assessments to be performed by biological dosimetry in case of a radiological or nuclear accident;
  • Perform biological dosimetry assessments, within the above mentioned organization or as a service, for proven or suspected radiation overdoses in the case of a radiological or nuclear accident, or in the medical sector and professional sector (workers, patients), in agreement with the policy defined by the Institute;
  • Study the operational application of new biological dosimetry methods to reconstitute the dose received by a person exposed to ionizing radiation of any type (external, internal, heterogeneous, localized, past);
  • Participate in the research carried out within the radiology and epidemiology service on biological diagnostic and prognostic indicators making it possible to better estimate radiation induced damage, and to study their operational application.
